It provides a simple, platform-independent API for +creating windows and contexts, reading input, handling events, etc. + +Version 3.1 adds improved documentation, support for custom system cursors, file +drop events, main thread wake-up, window frame size retrieval, floating windows, +character input with modifier keys, single buffered windows, build improvements +and fixes for a large number of bugs. + +If you are new to GLFW, you may find the +[introductory tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW +3 useful. If you have used GLFW 2 in the past, there is a +[transition guide](http://www.glfw.org/docs/latest/moving.html) for moving to +the GLFW 3 API. + +Note that a number of source files have been added or renamed in 3.1, which may +require you to update any custom build files you have. + + +## Compiling GLFW + +See the [Compiling GLFW](http://www.glfw.org/docs/latest/compile.html) guide in +the GLFW documentation. + + +## Using GLFW + +See the +[Building programs that use GLFW](http://www.glfw.org/docs/latest/build.html) +guide in the GLFW documentation. + + +## Reporting bugs + +Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues). +Please always include the name and version of the OS where the bug occurs and +the version of GLFW used. If you have cloned it, include the commit ID used. + +If it's a build issue, please also include the build log and the name and +version of your development environment. + +If it's a context creation issue, please also include the make and model of your +graphics card and the version of your driver. + +This will help both us and other people experiencing the same bug. + + +## Dependencies + +GLFW bundles a number of dependencies in the `deps/` directory. + + -

For information on +how to write such applications, start with the [introductory tutorial](@ref quick). +For information on how to compile the GLFW library itself, see the @ref compile +guide. + +This is not a tutorial on compilation or linking. It assumes basic +understanding of how to compile and link a C program as well as how to use the +specific compiler of your chosen development environment. The compilation +and linking process should be explained in your C programming material and in +the documentation for your development environment. + +@section build_include Including the GLFW header file + +In the source files of your application where you use OpenGL or GLFW, you should +include the GLFW header file, i.e.: + +@code +#include +@endcode + +The GLFW header declares the GLFW API and by default also includes the OpenGL +header of your development environment, which in turn defines all the constants, +types and function prototypes of the OpenGL API. + +The GLFW header also defines everything necessary for your OpenGL header to +function. For example, under Windows you are normally required to include +`windows.h` before the OpenGL header, which would pollute your code namespace +with the entire Win32 API. + +Instead, the GLFW header takes care of this for you, not by including +`windows.h`, but by duplicating only the very few necessary parts of it. It +does this only when needed, so if `windows.h` _is_ included, the GLFW header +does not try to redefine those symbols. The reverse is not true, i.e. +`windows.h` cannot cope if any of its symbols have already been defined. + +In other words: + + - Do _not_ include the OpenGL headers yourself, as GLFW does this for you + - Do _not_ include `windows.h` or other platform-specific headers unless you + plan on using those APIs directly + - If you _do_ need to include such headers, do it _before_ including + the GLFW header and it will handle this + +If you are using an OpenGL extension loading library such as +[glad](https://github.com/Dav1dde/glad), the extension loader header should +either be included _before_ the GLFW one, or the `GLFW_INCLUDE_NONE` macro +(described below) should be defined. + + +@subsection build_macros GLFW header option macros + +These macros may be defined before the inclusion of the GLFW header and affect +its behavior. + +`GLFW_DLL` is required on Windows when using the GLFW DLL, to tell the compiler +that the GLFW functions are defined in a DLL. + +The following macros control which OpenGL or OpenGL ES API header is included. + +`GLFW_INCLUDE_GLCOREARB` makes the GLFW header include the modern +`GL/glcorearb.h` header (`OpenGL/gl3.h` on OS X) instead of the regular OpenGL +header. + +`GLFW_INCLUDE_ES1` makes the GLFW header include the OpenGL ES 1.x `GLES/gl.h` +header instead of the regular OpenGL header. + +`GLFW_INCLUDE_ES2` makes the GLFW header include the OpenGL ES 2.0 `GLES2/gl2.h` +header instead of the regular OpenGL header. + +`GLFW_INCLUDE_ES3` makes the GLFW header include the OpenGL ES 3.0 `GLES3/gl3.h` +header instead of the regular OpenGL header. + +`GLFW_INCLUDE_ES31` makes the GLFW header include the OpenGL ES 3.1 `GLES3/gl31.h` +header instead of the regular OpenGL header. + +`GLFW_INCLUDE_NONE` makes the GLFW header not include any OpenGL or OpenGL ES API +header. This is useful in combination with an extension loading library. + +If none of the above inclusion macros are defined, the standard OpenGL `GL/gl.h` +header (`OpenGL/gl.h` on OS X) is included. + +`GLFW_INCLUDE_GLEXT` makes the GLFW header include the appropriate extension +header for the OpenGL or OpenGL ES header selected above after and _in addition +to_ that header. + +`GLFW_INCLUDE_GLU` makes the header include the GLU header _in addition to_ the +header selected above. This should only be used with the standard OpenGL header +and only for legacy code. GLU has been deprecated and should not be used in new +code. + +@note GLFW does not provide any of the API headers mentioned above. They must +be provided by your development environment or your OpenGL or OpenGL ES SDK. + + +@section build_link Link with the right libraries + +GLFW is essentially a wrapper of various platform-specific APIs and therefore +needs to link against many different system libraries. If you are using GLFW as +a shared library / dynamic library / DLL then it takes care of these links. +However, if you are using GLFW as a static library then your executable will +need to link against these libraries. + +On Windows and OS X, the list of system libraries is static and can be +hard-coded into your build environment. See the section for your development +environment below. On Linux and other Unix-like operating systems, the list +varies but can be retrieved in various ways as described below. + +A good general introduction to linking is +[Beginner's Guide to Linkers](http://www.lurklurk.org/linkers/linkers.html) by +David Drysdale. + + +@subsection build_link_win32 With MinGW or Visual C++ on Windows + +The static version of the GLFW library is named `glfw3`. When using this +version, it is also necessary to link with some libraries that GLFW uses. + +When linking an application under Windows that uses the static version of GLFW, +you must link with `opengl32`. On some versions of MinGW, you must also +explicitly link with `gdi32`, while other versions of MinGW include it in the +set of default libraries along with other dependencies like `user32` and +`kernel32`. If you are using GLU, you must also link with `glu32`. + +The link library for the GLFW DLL is named `glfw3dll`. When compiling an +application that uses the DLL version of GLFW, you need to define the `GLFW_DLL` +macro _before_ any inclusion of the GLFW header.

If the running window manager does not support this protocol, +the user will not be notified if the application locks up. + +GLFW uses the EWMH `_NET_WM_STATE_FULLSCREEN` window state to tell the window +manager to make the GLFW window full screen. If the running window manager does +not support this state, full screen windows may not work properly. GLFW has +a fallback code path in case this state is unavailable, but every window manager +behaves slightly differently in this regard. + +GLFW uses the EWMH `_NET_WM_BYPASS_COMPOSITOR` window property to tell a +compositing window manager to un-redirect full screen GLFW windows. If the +running window manager uses compositing but does not support this property then +additional copying may be performed for each buffer swap of full screen windows. + +GLFW uses the +[clipboard manager protocol](http://www.freedesktop.org/wiki/ClipboardManager/) +to push a clipboard string (i.e. selection) owned by a GLFW window about to be +destroyed to the clipboard manager. If there is no running clipboard manager, +the clipboard string will be unavailable once the window has been destroyed. + +GLFW uses the +[X drag-and-drop protocol](http://www.freedesktop.org/wiki/Specifications/XDND/) +to provide file drop events.

Go ahead and compile the actual GLFW library with +these files, as you would with any other project. + +Once the GLFW library is compiled, you are ready to build your applications, +linking it to the GLFW library. See the @ref build guide for more information. + + +@subsection compile_options CMake options + +The CMake files for GLFW provide a number of options, although not all are +available on all supported platforms. Some of these are de facto standards +among projects using CMake and so have no `GLFW_` prefix. + +If you are using the GUI version of CMake, these are listed and can be changed +from there. If you are using the command-line version, use the `ccmake` tool. +Some package systems like Ubuntu and other distributions based on Debian +GNU/Linux have this tool in a separate `cmake-curses-gui` package. + + +@subsubsection compile_options_shared Shared CMake options + +`BUILD_SHARED_LIBS` determines whether GLFW is built as a static +library or as a DLL / shared library / dynamic library. + +`LIB_SUFFIX` affects where the GLFW shared /dynamic library is installed. If it +is empty, it is installed to `${CMAKE_INSTALL_PREFIX}/lib`. If it is set to +`64`, it is installed to `${CMAKE_INSTALL_PREFIX}/lib64`. + +`GLFW_CLIENT_LIBRARY` determines which client API library to use. If set to +`opengl` the OpenGL library is used, if set to `glesv1` for the OpenGL ES 1.x +library is used, or if set to `glesv2` the OpenGL ES 2.0 library is used. The +selected library and its header files must be present on the system for this to +work. + +`GLFW_BUILD_EXAMPLES` determines whether the GLFW examples are built +along with the library. + +`GLFW_BUILD_TESTS` determines whether the GLFW test programs are +built along with the library. + +`GLFW_BUILD_DOCS` determines whether the GLFW documentation is built along with +the library. + + +@subsubsection compile_options_osx OS X specific CMake options + +`GLFW_USE_CHDIR` determines whether `glfwInit` changes the current +directory of bundled applications to the `Contents/Resources` directory. + +`GLFW_USE_MENUBAR` determines whether the first call to +`glfwCreateWindow` sets up a minimal menu bar. + +`GLFW_USE_RETINA` determines whether windows will use the full resolution of +Retina displays. + +`GLFW_BUILD_UNIVERSAL` determines whether to build Universal Binaries. + + +@subsubsection compile_options_win32 Windows specific CMake options + +`USE_MSVC_RUNTIME_LIBRARY_DLL` determines whether to use the DLL version or the +static library version of the Visual C++ runtime library. If set to `ON`, the +DLL version of the Visual C++ library is used. It is recommended to set this to +`ON`, as this keeps the executable smaller and benefits from security and bug +fix updates of the Visual C++ runtime. + +`GLFW_USE_DWM_SWAP_INTERVAL` determines whether the swap interval is set even +when DWM compositing is enabled. If this is `ON`, the swap interval is set even +if DWM is enabled. It is recommended to set this to `OFF`, as doing otherwise +can lead to severe jitter. + +`GLFW_USE_OPTIMUS_HPG` determines whether to export the `NvOptimusEnablement` +symbol, which forces the use of the high-performance GPU on Nvidia Optimus +systems. This symbol needs to be exported by the EXE to be detected by the +driver, so the override will not work if GLFW is built as a DLL. See _Enabling +High Performance Graphics Rendering on Optimus Systems_ for more details. + + +@subsubsection compile_options_egl EGL specific CMake options + +`GLFW_USE_EGL` determines whether to use EGL instead of the platform-specific +context creation API. Note that EGL is not yet provided on all supported +platforms. + + +@section compile_manual Compiling GLFW manually + +If you wish to compile GLFW without its CMake build environment then you will +have to do at least some of the platform detection yourself. GLFW needs +a number of configuration macros to be defined in order to know what it's being +compiled for and has many optional, platform-specific ones for various features. + +When building with CMake, the `glfw_config.h` configuration header is generated +based on the current platform and CMake options. The GLFW CMake environment +defines `_GLFW_USE_CONFIG_H`, which causes this header to be included by +`internal.h`. Without this macro, GLFW will expect the necessary configuration +macros to be defined on the command-line. + +Three macros _must_ be defined when compiling GLFW: one selecting the window +creation API, one selecting the context creation API and one client library. +Exactly one of each kind must be defined for GLFW to compile and link. + +The window creation API is used to create windows, handle input, monitors, gamma +ramps and clipboard. The options are: + + - `_GLFW_COCOA` to use the Cocoa frameworks + - `_GLFW_WIN32` to use the Win32 API + - `_GLFW_X11` to use the X Window System + - `_GLFW_WAYLAND` to use the Wayland API (experimental and incomplete) + - `_GLFW_MIR` to use the Mir API (experimental and incomplete) + +The context creation API is used to enumerate pixel formats / framebuffer +configurations and to create contexts. The options are: + + - `_GLFW_NSGL` to use the Cocoa OpenGL framework + - `_GLFW_WGL` to use the Win32 WGL API + - `_GLFW_GLX` to use the X11 GLX API + - `_GLFW_EGL` to use the EGL API + +Wayland and Mir both require the EGL backend. + +The client library is the one providing the OpenGL or OpenGL ES API, which is +used by GLFW to probe the created context. This is not the same thing as the +client API, as many desktop OpenGL client libraries now expose the OpenGL ES API +through extensions. The options are: + + - `_GLFW_USE_OPENGL` for the desktop OpenGL (opengl32.dll, libGL.so or + OpenGL.framework) + - `_GLFW_USE_GLESV1` for OpenGL ES 1.x (experimental) + - `_GLFW_USE_GLESV2` for OpenGL ES 2.x (experimental) + +Note that `_GLFW_USE_GLESV1` and `_GLFW_USE_GLESV2` may only be used with EGL, +as the other context creation APIs do not interface with OpenGL ES client +libraries. + +If you are building GLFW as a shared library / dynamic library / DLL then you +must also define `_GLFW_BUILD_DLL`. Otherwise, you may not define it. + +If you are using the X11 window creation API then you _must_ also select an entry +point retrieval mechanism. + + - `_GLFW_HAS_GLXGETPROCADDRESS` to use `glXGetProcAddress` (recommended) + - `_GLFW_HAS_GLXGETPROCADDRESSARB` to use `glXGetProcAddressARB` (legacy) + - `_GLFW_HAS_GLXGETPROCADDRESSEXT` to use `glXGetProcAddressEXT` (legacy) + - `_GLFW_HAS_DLOPEN` to do manual retrieval with `dlopen` (fallback) + +If you are using the Cocoa window creation API, the following options are +available: + + - `_GLFW_USE_CHDIR` to `chdir` to the `Resources` subdirectory of the + application bundle during @ref glfwInit (recommended) + - `_GLFW_USE_MENUBAR` to create and populate the menu bar when the first window + is created (recommended) + - `_GLFW_USE_RETINA` to have windows use the full resolution of Retina displays + (recommended) + +*/ diff --git a/testbed/glfw/docs/context.dox b/testbed/glfw/docs/context.dox new file mode 100644 index 00000000..eaa754b8 --- /dev/null +++ b/testbed/glfw/docs/context.dox @@ -0,0 +1,329 @@ +/*! + +@page context Context guide + +@tableofcontents + +This guide introduces the OpenGL and OpenGL ES context related functions of +GLFW.

See +[context related hints](@ref window_hints_ctx) in the window guide. + + +@subsection context_sharing Context object sharing + +When creating a window and its OpenGL or OpenGL ES context with @ref +glfwCreateWindow, you can specify another window whose context the new one +should share its objects (textures, vertex and element buffers, etc.) with. + +@code +GLFWwindow* second_window = glfwCreateWindow(640, 480, "Second Window", NULL, first_window); +@endcode + +Object sharing is implemented by the operating system and graphics driver. On +platforms where it is possible to choose which types of objects are shared, GLFW +requests that all types are shared. + +See the relevant chapter of the [OpenGL](https://www.opengl.org/registry/) or +[OpenGL ES](http://www.khronos.org/opengles/) reference documents for more +information. The name and number of this chapter unfortunately varies between +versions and APIs, but has at times been named _Shared Objects and Multiple +Contexts_. + +GLFW comes with a simple object sharing test program called `sharing`. + + +@subsection context_offscreen Offscreen contexts + +GLFW doesn't support creating contexts without an associated window. However, +contexts with hidden windows can be created with the +[GLFW_VISIBLE](@ref window_hints_wnd) window hint. + +@code +glfwWindowHint(GLFW_VISIBLE, GL_FALSE); + +GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL); +@endcode + +The window never needs to be shown and its context can be used as a plain +offscreen context. Depending on the window manager, the size of a hidden +window's framebuffer may not be usable or modifiable, so framebuffer +objects are recommended for rendering with such contexts. + +__OS X:__ The first time a window is created the menu bar is populated with +common commands like Hide, Quit and About. This is not desirable for example +when writing a command-line only application. The menu bar setup can be +disabled with a [compile-time option](@ref compile_options_osx). + + +@section context_current Current context + +Before you can make OpenGL or OpenGL ES calls, you need to have a current +context of the correct type. A context can only be current for a single thread +at a time, and a thread can only have a single context current at a time. + +The context of a window is made current with @ref glfwMakeContextCurrent. + +@code +glfwMakeContextCurrent(window); +@endcode + +The window of the current context is returned by @ref glfwGetCurrentContext. + +@code +GLFWwindow* window = glfwGetCurrentContext(); +@endcode + +The following GLFW functions require a context to be current. Calling any these +functions without a current context will generate a @ref GLFW_NO_CURRENT_CONTEXT +error. + + - @ref glfwSwapInterval + - @ref glfwExtensionSupported + - @ref glfwGetProcAddress + + +@section context_swap Buffer swapping + +Buffer swapping is part of the window and framebuffer, not the context. See +@ref buffer_swap. + + +@section context_glext OpenGL and OpenGL ES extensions + +One of the benefits of OpenGL and OpenGL ES are their extensibility. +Hardware vendors may include extensions in their implementations that extend the +API before that functionality is included in a new version of the OpenGL or +OpenGL ES specification, and some extensions are never included and remain +as extensions until they become obsolete. + +An extension is defined by: + +- An extension name (e.g. `GL_ARB_debug_output`) +- New OpenGL tokens (e.g. `GL_DEBUG_SEVERITY_HIGH_ARB`) +- New OpenGL functions (e.g. `glGetDebugMessageLogARB`) + +Note the `ARB` affix, which stands for Architecture Review Board and is used +for official extensions. The extension above was created by the ARB, but there +are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD. Any +group may also use the generic `EXT` affix. Lists of extensions, together with +their specifications, can be found at the +[OpenGL Registry](http://www.opengl.org/registry/) and +[OpenGL ES Registry](https://www.khronos.org/registry/gles/). + + +@subsection context_glext_auto Loading extension with a loader library + +An extension loader library is the easiest and best way to access both OpenGL and +OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. +They will take care of all the details of declaring and loading everything you +need. One such library is [glad](https://github.com/Dav1dde/glad) and there are +several others. + +The following example will use glad but all extension loader libraries work +similarly. + +First you need to generate the source files using the glad Python script. This +example generates a loader for any version of OpenGL, which is the default for +both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific +API versions and extension sets can be generated. The generated files are +written to the `output` directory. + +@code{.sh} +python main.py --generator c --no-loader --out-path output +@endcode + +The `--no-loader` option is added because GLFW already provides a function for +loading OpenGL and OpenGL ES function pointers and glad can call this instead of +having to implement its own. There are several other command-line options as +well. See the glad documentation for details. + +Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and +`output/include/KHR/khrplatform.h` files to your build. Then you need to +include the glad header file, which will replace the OpenGL header of your +development environment. By including the glad header before the GLFW header, +it suppresses the development environment's OpenGL or OpenGL ES header. + +@code +#include +#include +@endcode + +Finally you need to initialize glad once you have a suitable current context. + +@code +window = glfwCreateWindow(640, 480, "My Window", NULL, NULL); +if (!window) +{ + ... +} + +glfwMakeContextCurrent(window); + +gladLoadGLLoader((GLADloadproc) glfwGetProcAddress); +@endcode + +Once glad has been loaded, you have access to all OpenGL core and extension +functions supported by both the context you created and the glad loader you +generated and you are ready to start rendering. + +You can specify a minimum required OpenGL or OpenGL ES version with +[context hints](@ref window_hints_ctx). If your needs are more complex, you can +check the actual OpenGL or OpenGL ES version with +[context attributes](@ref window_attribs_ctx), or you can check whether +a specific version is supported by the current context with the +`GLAD_GL_VERSION_x_x` booleans. + +@code +if (GLAD_GL_VERSION_3_2) +{ + // Call OpenGL 3.2+ specific code +} +@endcode + +To check whether a specific extension is supported, use the `GLAD_GL_xxx` +booleans. + +@code +if (GLAD_GL_ARB_debug_output) +{ + // Use GL_ARB_debug_output +} +@endcode + + +@subsection context_glext_manual Loading extensions manually + +__Do not use this technique__ unless it is absolutely necessary. An +[extension loader library](@ref context_glext_auto) will save you a ton of +tedious, repetitive, error prone work. + +To use a certain extension, you must first check whether the context supports +that extension and then, if it introduces new functions, retrieve the pointers +to those functions. GLFW provides @ref glfwExtensionSupported and @ref +glfwGetProcAddress for manual loading of extensions and new API functions. + +This section will demonstrate manual loading of OpenGL extensions. The loading +of OpenGL ES extensions is identical except for the name of the extension header. + + +@subsubsection context_glext_header The glext.h header + +The `glext.h` extension header is a continually updated file that defines the +interfaces for all OpenGL extensions. The latest version of this can always be +found at the [OpenGL Registry](http://www.opengl.org/registry/). There are also +extension headers for the various versions of OpenGL ES at the +[OpenGL ES Registry](https://www.khronos.org/registry/gles/). It it strongly +recommended that you use your own copy of the extension header, as the one +included in your development environment may be several years out of date and +may not include the extensions you wish to use. + +The header defines function pointer types for all functions of all extensions it +supports. These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for +`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer +to function) and `PROC` (procedure) are added to the ends. + +To include the extension header, define [GLFW_INCLUDE_GLEXT](@ref build_macros) +before including the GLFW header. + +@code +#define GLFW_INCLUDE_GLEXT +#include +@endcode + + +@subsubsection context_glext_string Checking for extensions + +A given machine may not actually support the extension (it may have older +drivers or a graphics card that lacks the necessary hardware features), so it +is necessary to check at run-time whether the context supports the extension. +This is done with @ref glfwExtensionSupported. + +@code +if (glfwExtensionSupported("GL_ARB_debug_output")) +{ + // The extension is supported by the current context +} +@endcode + +The argument is a null terminated ASCII string with the extension name. If the +extension is supported, @ref glfwExtensionSupported returns `GL_TRUE`, otherwise +it returns `GL_FALSE`. + + +@subsubsection context_glext_proc Fetching function pointers + +Many extensions, though not all, require the use of new OpenGL functions. +These functions often do not have entry points in the client API libraries of +your operating system, making it necessary to fetch them at run time. You can +retrieve pointers to these functions with @ref glfwGetProcAddress. + +@code +PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB"); +@endcode + +In general, you should avoid giving the function pointer variables the (exact) +same name as the function, as this may confuse your linker. Instead, you can +use a different prefix, like above, or some other naming scheme. + +Now that all the pieces have been introduced, here is what they might look like +when used together. + +@code +#define GLFW_INCLUDE_GLEXT +#include + +#define glGetDebugMessageLogARB pfnGetDebugMessageLog +PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog; + +// Flag indicating whether the extension is supported +int has_ARB_debug_output = 0; + +void load_extensions(void) +{ + if (glfwExtensionSupported("GL_ARB_debug_output")) + { + pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC) glfwGetProcAddress("glGetDebugMessageLogARB"); + if (pfnGetDebugMessageLog) + { + // Both the extension name and the function pointer are present + has_ARB_debug_output = 1; + } + } +} + +void some_function(void) +{ + if (has_ARB_debug_output) + { + // Now the extension function can be called as usual + glGetDebugMessageLogARB(...); + } +} +@endcode + +*/ diff --git

There are also +guides for the other areas of GLFW. + + - @ref intro + - @ref window + - @ref context + - @ref monitor + +GLFW provides many kinds of input. While some can only be polled, like time, or +only received via callbacks, like scrolling, there are those that provide both +callbacks and polling. Where a callback is provided, that is the recommended +way to receive that kind of input. The more you can use callbacks the less time +your users' machines will need to spend polling. + +All input callbacks receive a window handle. By using the +[window user pointer](@ref window_userptr), you can access non-global structures +or objects from your callbacks. + +To get a better feel for how the various events callbacks behave, run the +`events` test program. It register every callback supported by GLFW and prints +out all arguments provided for every event, along with time and sequence +information. + + +@section events Event processing + +GLFW needs to communicate regularly with the window system both in order to +receive events and to show that the application hasn't locked up. Event +processing must be done regularly while you have visible windows and is normally +done each frame after [buffer swapping](@ref buffer_swap). + +There are two functions for processing pending events. @ref glfwPollEvents, +processes only those events that have already been received and then returns +immediately. + +@code +glfwPollEvents(); +@endcode + +This is the best choice when rendering continually, like most games do. + +If you only need to update the contents of the window when you receive new +input, @ref glfwWaitEvents is a better choice. + +@code +glfwWaitEvents(); +@endcode + +It puts the thread to sleep until at least one event has been received and then +processes all received events. This saves a great deal of CPU cycles and is +useful for, for example, editing tools. There must be at least one GLFW window +for this function to sleep. + +If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from +another thread by posting an empty event to the event queue with @ref +glfwPostEmptyEvent. + +@code +glfwPostEmptyEvent(); +@endcode + +Do not assume that callbacks will _only_ be called through either of the above +functions. While it is necessary to process events in the event queue, some +window systems will send some events directly to the application, which in turn +causes callbacks to be called outside of regular event processing. + + +@section input_keyboard Keyboard input + +GLFW divides keyboard input into two categories; key events and character +events. Key events relate to actual physical keyboard keys, whereas character +events relate to the Unicode code points generated by pressing some of them. + +Keys and characters do not map 1:1. A single key press may produce several +characters, and a single character may require several keys to produce. This +may not be the case on your machine, but your users are likely not all using the +same keyboard layout, input method or even operating system as you. + + +@subsection input_key Key input + +If you wish to be notified when a physical key is pressed or released or when it +repeats, set a key callback. + +@code +glfwSetKeyCallback(window, key_callback); +@endcode + +The callback function receives the [keyboard key](@ref keys), platform-specific +scancode, key action and [modifier bits](@ref mods). + +@code +void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) +{ + if (key == GLFW_KEY_E && action == GLFW_PRESS) + activate_airship(); +} +@endcode + +The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key +will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it. These keys still +have unique, if platform-specific scancodes. + +The scancode is unique for every key but is platform-specific, so a scancode +will map to different keys on different platforms. + +The key will be `GLFW_KEY_UNKNOWN` for special keys like _E-mail_ or _Play_ that +don't have a key token. Those keys will still have unique, if platform-specific +scancodes. + +Key states for [named keys](@ref keys) are also saved in per-window state arrays +that can be polled with @ref glfwGetKey. + +@code +int state = glfwGetKey(window, GLFW_KEY_E); +if (state == GLFW_PRESS) + activate_airship(); +@endcode + +The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +This function only returns cached key event state. It does not poll the +system for the current state of the key. + +Whenever you poll state, you risk missing the state change you are looking for. +If a pressed key is released again before you poll its state, you will have +missed the key press. The recommended solution for this is to use a +key callback, but there is also the `GLFW_STICKY_KEYS` input mode. + +@code +glfwSetInputMode(window, GLFW_STICKY_KEYS, 1); +@endcode + +When sticky keys mode is enabled, the pollable state of a key will remain +`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey. Once +it has been polled, if a key release event had been processed in the meantime, +the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`. + +The `GLFW_KEY_LAST` constant holds the highest value of any +[named key](@ref keys). + + +@subsection input_char Text input + +GLFW supports text input in the form of a stream of +[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the +operating system text input system. Unlike key input, text input obeys keyboard +layouts and modifier keys and supports composing characters using +[dead keys](https://en.wikipedia.org/wiki/Dead_key). Once received, you can +encode the code points into +[UTF-8](https://en.wikipedia.org/wiki/UTF-8) or any other encoding you prefer. + +Because an `unsigned int` is 32 bits long on all platforms supported by GLFW, +you can treat the code point argument as native endian +[UTF-32](https://en.wikipedia.org/wiki/UTF-32). + +There are two callbacks for receiving Unicode code points. If you wish to +offer regular text input, set a character callback. + +@code +glfwSetCharCallback(window, character_callback); +@endcode + +The callback function receives Unicode code points for key events that would +have led to regular text input and generally behaves as a standard text field on +that platform. + +@code +void character_callback(GLFWwindow* window, unsigned int codepoint) +{ +} +@endcode + +If you wish to receive even those Unicode code points generated with modifier +key combinations that a plain text field would ignore, or just want to know +exactly what modifier keys were used, set a character with modifiers callback. + +@code +glfwSetCharModsCallback(window, charmods_callback); +@endcode + +The callback function receives Unicode code points and +[modifier bits](@ref mods). + +@code +void charmods_callback(GLFWwindow* window, unsigned int codepoint, int mods) +{ +} +@endcode + + +@section input_mouse Mouse input + +Mouse input comes in many forms, including cursor motion, button presses and +scrolling offsets. The cursor appearance can also be changed, either to +a custom image or a standard cursor shape from the system theme. + + +@subsection cursor_pos Cursor position + +If you wish to be notified when the cursor moves over the window, set a cursor +position callback. + +@code +glfwSetCursorPosCallback(window, cursor_pos_callback); +@endcode + +The callback functions receives the cursor position. On platforms that provide +it, the full sub-pixel cursor position is passed on. + +@code +static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos) +{ +} +@endcode + +The cursor position is also saved per-window and can be polled with @ref +glfwGetCursorPos. + +@code +double xpos, ypos; +glfwGetCursorPos(window, &xpos, &ypos); +@endcode + + +@subsection cursor_mode Cursor modes + +The `GLFW_CURSOR` input mode provides several cursor modes for special forms of +mouse motion input. By default, the cursor mode is `GLFW_CURSOR_NORMAL`, +meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor) +is used and cursor motion is not limited. + +If you wish to implement mouse motion based camera controls or other input +schemes that require unlimited mouse movement, set the cursor mode to +`GLFW_CURSOR_DISABLED`. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); +@endcode + +This will hide the cursor and lock it to the specified window. GLFW will then +take care of all the details of cursor re-centering and offset calculation and +providing the application with a virtual cursor position. This virtual position +is provided normally via both the cursor position callback and through polling. + +@note You should not implement your own version of this functionality using +other features of GLFW. It is not supported and will not work as robustly as +`GLFW_CURSOR_DISABLED`. + +If you just wish the cursor to become hidden when it is over a window, set +the cursor mode to `GLFW_CURSOR_HIDDEN`. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN); +@endcode + +This mode puts no limit on the motion of the cursor. + +To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL` +cursor mode. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL); +@endcode + + +@subsection cursor_object Cursor objects + +GLFW supports creating both custom and system theme cursor images, encapsulated +as @ref GLFWcursor objects. They are created with @ref glfwCreateCursor or @ref +glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref +glfwTerminate, if any remain. + + +@subsubsection cursor_custom Custom cursor creation + +A custom cursor is created with @ref glfwCreateCursor, which returns a handle to +the created cursor object. For example, this creates a 16x16 white square +cursor with the hot-spot in the upper-left corner: + +@code +unsigned char pixels[16 * 16 * 4]; +memset(pixels, 0xff, sizeof(pixels)); + +GLFWimage image; +image.width = 16; +image.height = 16; +image.pixels = pixels; + +GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0); +@endcode + +If cursor creation fails, `NULL` will be returned, so it is necessary to check +the return value. + +The image data is 32-bit RGBA, i.e. eight bits per channel. The pixels are +arranged canonically as sequential rows, starting from the top-left corner. + + +@subsubsection cursor_standard Standard cursor creation + +A cursor with a [standard shape](@ref shapes) from the current system cursor +theme can be can be created with @ref glfwCreateStandardCursor. + +@code +GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR); +@endcode + +These cursor objects behave in the exact same way as those created with @ref +glfwCreateCursor except that the system cursor theme provides the actual image. + + +@subsubsection cursor_destruction Cursor destruction + +When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor. + +@code +glfwDestroyCursor(cursor); +@endcode + +Cursor destruction always succeeds. All cursors remaining when @ref +glfwTerminate is called are destroyed as well. + + +@subsubsection cursor_set Cursor setting + +A cursor can be set as current for a window with @ref glfwSetCursor. + +@code +glfwSetCursor(window, cursor); +@endcode + +Once set, the cursor image will be used as long as the system cursor is over the +client area of the window and the [cursor mode](@ref cursor_mode) is set +to `GLFW_CURSOR_NORMAL`. + +A single cursor may be set for any number of windows. + +To remove a cursor from a window, set the cursor of that window to `NULL`. + +@code +glfwSetCursor(window, NULL); +@endcode + +When a cursor is destroyed, it is removed from any window where it is set. This +does not affect the cursor modes of those windows. + + +@subsection cursor_enter Cursor enter/leave events + +If you wish to be notified when the cursor enters or leaves the client area of +a window, set a cursor enter/leave callback. + +@code +glfwSetCursorEnterCallback(window, cursor_enter_callback); +@endcode + +The callback function receives the new classification of the cursor. + +@code +void cursor_enter_callback(GLFWwindow* window, int entered) +{ + if (entered) + { + // The cursor entered the client area of the window + } + else + { + // The cursor left the client area of the window + } +} +@endcode + + +@subsection input_mouse_button Mouse button input + +If you wish to be notified when a mouse button is pressed or released, set +a mouse button callback. + +@code +glfwSetMouseButtonCallback(window, mouse_button_callback); +@endcode + +The callback function receives the [mouse button](@ref buttons), button action +and [modifier bits](@ref mods). + +@code +void mouse_button_callback(GLFWwindow* window, int button, int action, int mods) +{ + if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS) + popup_menu(); +} +@endcode + +The action is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +Mouse button states for [named buttons](@ref buttons) are also saved in +per-window state arrays that can be polled with @ref glfwGetMouseButton. + +@code +int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT); +if (state == GLFW_PRESS) + upgrade_cow(); +@endcode + +The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +This function only returns cached mouse button event state. It does not poll +the system for the current state of the mouse button. + +Whenever you poll state, you risk missing the state change you are looking for. +If a pressed mouse button is released again before you poll its state, you will have +missed the button press. The recommended solution for this is to use a +mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS` +input mode. + +@code +glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, 1); +@endcode + +When sticky mouse buttons mode is enabled, the pollable state of a mouse button +will remain `GLFW_PRESS` until the state of that button is polled with @ref +glfwGetMouseButton. Once it has been polled, if a mouse button release event +had been processed in the meantime, the state will reset to `GLFW_RELEASE`, +otherwise it will remain `GLFW_PRESS`. + +The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any +[named button](@ref buttons). + + +@subsection scrolling Scroll input + +If you wish to be notified when the user scrolls, whether with a mouse wheel or +touchpad gesture, set a scroll callback. + +@code +glfwSetScrollCallback(window, scroll_callback); +@endcode + +The callback function receives two-dimensional scroll offsets. + +@code +void scroll_callback(GLFWwindow* window, double xoffset, double yoffset) +{ +} +@endcode + +A simple mouse wheel, being vertical, provides offsets along the Y-axis. + + +@section joystick Joystick input + +The joystick functions expose connected joysticks and controllers, with both +referred to as joysticks. It supports up to sixteen joysticks, ranging from +`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to `GLFW_JOYSTICK_LAST`. You can test +whether a [joystick](@ref joysticks) is present with @ref glfwJoystickPresent. + +@code +int present = glfwJoystickPresent(GLFW_JOYSTICK_1); +@endcode + +When GLFW is initialized, detected joysticks are added to to the beginning of +the array, starting with `GLFW_JOYSTICK_1`. Once a joystick is detected, it +keeps its assigned index until it is disconnected, so as joysticks are connected +and disconnected, they will become spread out. + +Joystick state is updated as needed when a joystick function is called and does +not require a window to be created or @ref glfwPollEvents or @ref glfwWaitEvents +to be called. + + +@subsection joystick_axis Joystick axis states + +The positions of all axes of a joystick are returned by @ref +glfwGetJoystickAxes. See the reference documentation for the lifetime of the +returned array. + +@code +int count; +const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_1, &count); +@endcode + +Each element in the returned array is a value between -1.0 and 1.0. + + +@subsection joystick_button Joystick button states + +The states of all buttons of a joystick are returned by @ref +glfwGetJoystickButtons. See the reference documentation for the lifetime of the +returned array. + +@code +int count; +const unsigned char* axes = glfwGetJoystickButtons(GLFW_JOYSTICK_1, &count); +@endcode + +Each element in the returned array is either `GLFW_PRESS` or `GLFW_RELEASE`. + + +@subsection joystick_name Joystick name + +The human-readable, UTF-8 encoded name of a joystick is returned by @ref +glfwGetJoystickName. See the reference documentation for the lifetime of the +returned string. + +@code +const char* name = glfwGetJoystickName(GLFW_JOYSTICK_1); +@endcode + +Joystick names are not guaranteed to be unique. Two joysticks of the same model +and make may have the same name. Only the [joystick token](@ref joysticks) is +guaranteed to be unique, and only until that joystick is disconnected. + + +@section time Time input + +GLFW provides high-resolution time input, in seconds, with @ref glfwGetTime. + +@code +double seconds = glfwGetTime(); +@endcode + +It returns the number of seconds since the timer was started when the library +was initialized with @ref glfwInit. The platform-specific time sources used +usually have micro- or nanosecond resolution. + +You can modify the reference time with @ref glfwSetTime. + +@code +glfwSetTime(4.0); +@endcode + +This sets the timer to the specified time, in seconds. + + +@section clipboard Clipboard input and output + +If the system clipboard contains a UTF-8 encoded string or if it can be +converted to one, you can retrieve it with @ref glfwGetClipboardString. See the +reference documentation for the lifetime of the returned string. + +@code +const char* clipboard = glfwGetClipboardString(window); +@endcode + +The contents of the system clipboard can be set to a UTF-8 encoded string with +@ref glfwSetClipboardString. + +@code +glfwSetClipboardString(window, "A string with words in it"); +@endcode + +The clipboard functions take a window handle argument because some window +systems require a window to communicate with the system clipboard. Any valid +window may be used. + + +@section path_drop Path drop input + +If you wish to receive the paths of files and/or directories dropped on +a window, set a file drop callback. + +@code +glfwSetDropCallback(window, drop_callback); +@endcode + +The callback function receives an array of paths encoded as UTF-8. + +@code +void drop_callback(GLFWwindow* window, int count, const char** paths) +{ + int i; + for (i = 0; i < count; i++) + handle_dropped_file(paths[i]); +} +@endcode + +The path array and its strings are only valid until the file drop callback +returns, as they may have been generated specifically for that event.

This is done with @ref glfwTerminate. + +@code +glfwTerminate(); +@endcode + +This will destroy any remaining window, monitor and cursor objects, restore any +modified gamma ramps, re-enable the screensaver if it had been disabled and free +any resources allocated by GLFW. + +Once the library is terminated, it is as if it had never been initialized and +you will need to initialize it again before being able to use GLFW. If the +library was not initialized or had already been terminated, it return +immediately. + + +@section error_handling Error handling + +Some GLFW functions have return values that indicate an error, but this is often +not very helpful when trying to figure out _why_ the error occurred. Some +functions also return otherwise valid values on error. Finally, far from all +GLFW functions have return values. + +This is where the error callback comes in. This callback is called whenever an +error occurs. It is set with @ref glfwSetErrorCallback, a function that may be +called regardless of whether GLFW is initialized. + +@code +glfwSetErrorCallback(error_callback); +@endcode + +The error callback receives a human-readable description of the error and (when +possible) its cause. The description encoded as UTF-8. The callback is also +provided with an [error code](@ref errors). + +@code +void error_callback(int error, const char* description) +{ + puts(description); +} +@endcode + +The error code indicates the general category of the error. Some error codes, +such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like +@ref GLFW_PLATFORM_ERROR are used for many different errors. + +The description string is only valid until the error callback returns, as it may +have been generated specifically for that error. This lets GLFW provide much +more specific error descriptions but means you must make a copy if you want to +keep the description string. + + +@section coordinate_systems Coordinate systems + +GLFW has two primary coordinate systems: the _virtual screen_ and the window +_client area_ or _content area_. Both use the same unit: _virtual screen +coordinates_, or just _screen coordinates_, which don't necessarily correspond +to pixels. + + + +Both the virtual screen and the client area coordinate systems have the X-axis +pointing to the right and the Y-axis pointing down. + +Window and monitor positions are specified as the position of the upper-left +corners of their content areas relative to the virtual screen, while cursor +positions are specified relative to a window's client area. + +Because the origin of the window's client area coordinate system is also the +point from which the window position is specified, you can translate client area +coordinates to the virtual screen by adding the window position. The window +frame, when present, extends out from the client area but does not affect the +window position. + +Almost all positions and sizes in GLFW are measured in screen coordinates +relative to one of the two origins above. This includes cursor positions, +window positions and sizes, window frame sizes, monitor positions and video mode +resolutions. + +Two exceptions are the [monitor physical size](@ref monitor_size), which is +measured in millimetres, and [framebuffer size](@ref window_fbsize), which is +measured in pixels. + +Pixels and screen coordinates may map 1:1 on your machine, but they won't on +every other machine, for example on a Mac with a Retina display. The ratio +between screen coordinates and pixels may also change at run-time depending on +which monitor the window is currently considered to be on. + + +@section guarantees_limitations Guarantees and limitations + +This section describes the conditions under which GLFW can be expected to +function, barring bugs in the operating system or drivers. Use of GLFW outside +of these limits may work on some platforms, or on some machines, or some of the +time, or on some versions of GLFW, but it may break at any time and this will +not be considered a bug. + + +@subsection lifetime Pointer lifetimes + +GLFW will never free any pointer you provide to it and you must never free any +pointer it provides to you. + +Many GLFW functions return pointers to dynamically allocated structures, strings +or arrays, and some callbacks are provided with strings or arrays. These are +always managed by GLFW and should never be freed by the application. The +lifetime of these pointers is documented for each GLFW function and callback. +If you need to keep this data, you must copy it before its lifetime expires. + +Many GLFW functions accept pointers to structures or strings allocated by the +application. These are never freed by GLFW and are always the responsibility of +the application. If GLFW needs to keep the data in these structures or strings, +it is copied before the function returns. + +Pointer lifetimes are guaranteed not to be shortened in future minor or patch +releases. + + +@subsection reentrancy Reentrancy + +GLFW event processing and object creation and destruction are not reentrant. +This means that the following functions may not be called from any callback +function: + + - @ref glfwCreateWindow + - @ref glfwDestroyWindow + - @ref glfwCreateCursor + - @ref glfwCreateStandardCursor + - @ref glfwDestroyCursor + - @ref glfwPollEvents + - @ref glfwWaitEvents + - @ref glfwTerminate + +These functions may be made reentrant in future minor or patch releases, but +functions not on this list will not be made non-reentrant. + + +@subsection thread_safety Thread safety + +Most GLFW functions may only be called from the main thread, but some may be +called from any thread. However, no GLFW function may be called from any other +thread until GLFW has been successfully initialized on the main thread, +including functions that may called before initialization. + +The reference documentation for every GLFW function states whether it is limited +to the main thread. + +The following categories of functions are and will remain limited to the main +thread due to the limitations of one or several platforms: + + - Initialization and termination + - Event processing + - Creation and destruction of window, context and cursor objects + +Because event processing must be performed on the main thread, all callbacks +except for the error callback will only be called on that thread. The error +callback may be called on any thread, as any GLFW function may generate errors. + +The posting of empty events may be done from any thread. The window user +pointer and close flag may also be accessed and modified from any thread, but +this is not synchronized by GLFW. The following window related functions may +be called from any thread: + + - @ref glfwPostEmptyEvent + - @ref glfwGetWindowUserPointer + - @ref glfwSetWindowUserPointer + - @ref glfwWindowShouldClose + - @ref glfwSetWindowShouldClose + +Rendering may be done on any thread. The following context related functions +may be called from any thread: + + - @ref glfwMakeContextCurrent + - @ref glfwGetCurrentContext + - @ref glfwSwapBuffers + - @ref glfwSwapInterval + - @ref glfwExtensionSupported + - @ref glfwGetProcAddress + +The timer may be accessed from any thread, but this is not synchronized by GLFW. +The following timer related functions may be called from any thread: + + - @ref glfwGetTime + +Library version information may be queried from any thread. The following +version related functions may be called from any thread: + + - @ref glfwGetVersion + - @ref glfwGetVersionString + +GLFW uses no synchronization objects internally except for thread-local storage +to keep track of the current context for each thread. Synchronization is left +to the application. + +Functions that may currently be called from any thread will always remain so, +but functions that are currently limited to the main may be updated to allow +calls from any thread in future releases. + + +@subsection compatibility Version compatibility + +GLFW guarantees binary backward compatibility with earlier minor versions of the +API. This means that you can drop in a newer version of the GLFW DLL / shared +library / dynamic library and existing applications will continue to run. + +Once a function or constant has been added, the signature of that function or +value of that constant will remain unchanged until the next major version of +GLFW. No compatibility of any kind is guaranteed between major versions. + +Undocumented behavior, i.e. behavior that is not described in the documentation, +may change at any time until it is documented. + +If the reference documentation and the implementation differ, the reference +documentation is correct and the implementation will be fixed in the next +release. + + +@subsection event_order Event order + +The order of arrival of related events is not guaranteed to be consistent +across platforms. The exception is synthetic key and mouse button release +events, which are always delivered after the window defocus event. + + +@section intro_version Version management + +GLFW provides mechanisms for identifying what version of GLFW your application +was compiled against as well as what version it is currently running against. +If you are loading GLFW dynamically (not just linking dynamically), you can use +this to verify that the library binary is compatible with your application. + + +@subsection intro_version_compile Compile-time version + +The compile-time version of GLFW is provided by the GLFW header with the +`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros. + +@code +printf("Compiled against GLFW %i.%i.%i\n", + GLFW_VERSION_MAJOR, + GLFW_VERSION_MINOR, + GLFW_VERSION_REVISION); +@endcode + + +@subsection intro_version_runtime Run-time version + +The run-time version can be retrieved with @ref glfwGetVersion, a function that +may be called regardless of whether GLFW is initialized. + +@code +int major, minor, revision; +glfwGetVersion(&major, &minor, &revision); + +printf("Running against GLFW %i.%i.%i\n", major, minor, revision); +@endcode + + +@subsection intro_version_string Version string + +GLFW 3 also provides a compile-time generated version string that describes the +version, platform, compiler and any platform-specific compile-time options. +This is primarily intended for submitting bug reports, to allow developers to +see which code paths are enabled in a binary. + +The version string is returned by @ref glfwGetVersionString, a function that may +be called regardless of whether GLFW is initialized. + +__Do not use the version string__ to parse the GLFW library version. The @ref +glfwGetVersion function already provides the version of the running library +binary. + +The format of the string is as follows: + - The version of GLFW + - The name of the window system API + - The name of the context creation API + - Any additional options or APIs + +For example, when compiling GLFW 3.0 with MinGW using the Win32 and WGL +back ends, the version string may look something like this: + +@code +3.0.0 Win32 WGL MinGW +@endcode + +*/ diff --git a/testbed/glfw/docs/main.dox b/testbed/glfw/docs/main.dox new file mode 100644 index 00000000..e5caae0d --- /dev/null +++ b/testbed/glfw/docs/main.dox @@ -0,0 +1,47 @@ +/*! + +@mainpage notitle + +@section main_intro Introduction + +__GLFW__ is a free, Open Source, multi-platform library for creating windows +with OpenGL or OpenGL ES contexts and receiving many kinds of input.

They only supported +the Targa image format, making them mostly useful for beginner level examples. +To become of sufficiently high quality to warrant keeping them in GLFW 3, they +would need not only to support other formats, but also modern extensions to +OpenGL texturing.

Each window now has a close flag that is set to +`GL_TRUE` when the user attempts to close that window. By default, nothing else +happens and the window stays visible. It is then up to you to either destroy +the window, take some other action or simply ignore the request. + +You can query the close flag at any time with @ref glfwWindowShouldClose and set +it at any time with @ref glfwSetWindowShouldClose. + +@par Old basic main loop +@code +while (glfwGetWindowParam(GLFW_OPENED)) +{ + ... +} +@endcode + +@par New basic main loop +@code +while (!glfwWindowShouldClose(window)) +{ + ... +} +@endcode + +The close callback no longer returns a value.

The @ref glfwGetVideoModes function +now returns all available modes for a specific monitor instead of requiring you +to guess how large an array you need.

This was an artefact of the origin of GLFW, i.e. being developed in +English by a Swede. However, many keyboard layouts require more than one key to +produce characters with diacritical marks. Even the Swedish keyboard layout +requires this for uncommon cases like ü. + +@par Old syntax +@code +void GLFWCALL character_callback(int character, int action); +@endcode + +@par New syntax +@code +void character_callback(GLFWwindow* window, int character); +@endcode + + +@subsection moving_cursorpos Cursor position changes + +The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos, +`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref +glfwSetCursorPosCallback. + +The cursor position is now `double` instead of `int`, both for the direct +functions and for the callback. Some platforms can provide sub-pixel cursor +movement and this data is now passed on to the application where available. On +platforms where this is not provided, the decimal part is zero. + +GLFW 3 only allows you to position the cursor within a window using @ref +glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active. +Unless the window is active, the function fails silently. + + +@subsection moving_wheel Wheel position replaced by scroll offsets + +The `glfwGetMouseWheel` function has been removed. Scrolling is the input of +offsets and has no absolute position. The mouse wheel callback has been +replaced by a [scroll callback](@ref GLFWscrollfun) that receives +two-dimensional floating point scroll offsets. This allows you to receive +precise scroll data from for example modern touchpads. + +@par Old syntax +@code +void GLFWCALL mouse_wheel_callback(int position); +@endcode + +@par New syntax +@code +void scroll_callback(GLFWwindow* window, double xoffset, double yoffset); +@endcode + +@par Removed functions +`glfwGetMouseWheel` + + +@subsection moving_repeat Key repeat action + +The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled +for both keys and characters. A new key action, `GLFW_REPEAT`, has been added +to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press +from a repeat. Note that @ref glfwGetKey still returns only `GLFW_PRESS` or +`GLFW_RELEASE`. + + +@subsection moving_keys Physical key input + +GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to +the values generated by the current keyboard layout. The tokens are named +according to the values they would have using the standard US layout, but this +is only a convenience, as most programmers are assumed to know that layout. +This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and +is the same key in the same place regardless of what keyboard layouts the users +of your program has. + +The key input facility was never meant for text input, although using it that +way worked slightly better in GLFW 2. If you were using it to input text, you +should be using the character callback instead, on both GLFW 2 and 3. This will +give you the characters being input, as opposed to the keys being pressed. + +GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of +having to remember whether to check for `'a'` or `'A'`, you now check for +`GLFW_KEY_A`. + + +@subsection moving_joystick Joystick function changes + +The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes. + +The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and +`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent +function as well as axis and button counts returned by the @ref +glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions. + + +@subsection moving_mbcs Win32 MBCS support + +The Win32 port of GLFW 3 will not compile in +[MBCS mode](http://msdn.microsoft.com/en-us/library/5z097dxa.aspx). +However, because the use of the Unicode version of the Win32 API doesn't affect +the process as a whole, but only those windows created using it, it's perfectly +possible to call MBCS functions from other parts of the same application. +Therefore, even if an application using GLFW has MBCS mode code, there's no need +for GLFW itself to support it. + + +@subsection moving_windows Support for versions of Windows older than XP + +All explicit support for version of Windows older than XP has been removed. +There is no code that actively prevents GLFW 3 from running on these earlier +versions, but it uses Win32 functions that those versions lack. + +Windows XP was released in 2001, and by now (January 2015) it has not only +replaced almost all earlier versions of Windows, but is itself rapidly being +replaced by Windows 7 and 8. The MSDN library doesn't even provide +documentation for version older than Windows 2000, making it difficult to +maintain compatibility with these versions even if it was deemed worth the +effort. + +The Win32 API has also not stood still, and GLFW 3 uses many functions only +present on Windows XP or later. Even supporting an OS as new as XP (new +from the perspective of GLFW 2, which still supports Windows 95) requires +runtime checking for a number of functions that are present only on modern +version of Windows. + + +@subsection moving_syskeys Capture of system-wide hotkeys + +The ability to disable and capture system-wide hotkeys like Alt+Tab has been +removed.

The +application will create a window and OpenGL context, render a rotating triangle +and exit when the user closes the window or presses Escape. This guide will +introduce a few of the most commonly used functions, but there are many more. + +This guide assumes no experience with earlier versions of GLFW. If you +have used GLFW 2 in the past, read the @ref moving guide, as some functions +behave differently in GLFW 3. + + +@section quick_steps Step by step + +@subsection quick_include Including the GLFW header + +In the source files of your application where you use OpenGL or GLFW, you need +to include the GLFW 3 header file. + +@code +#include +@endcode + +This defines all the constants, types and function prototypes of the GLFW API. +It also includes the OpenGL header, and defines all the constants and types +necessary for it to work on your platform. + +For example, under Windows you are normally required to include `windows.h` +before including `GL/gl.h`. This would make your source file tied to Windows +and pollute your code's namespace with the whole Win32 API. + +Instead, the GLFW header takes care of this for you, not by including +`windows.h`, but rather by itself duplicating only the necessary parts of it. +It does this only where needed, so if `windows.h` _is_ included, the GLFW header +does not try to redefine those symbols. + +In other words: + +- Do _not_ include the OpenGL headers yourself, as GLFW does this for you +- Do _not_ include `windows.h` or other platform-specific headers unless + you plan on using those APIs directly +- If you _do_ need to include such headers, do it _before_ including the + GLFW one and it will detect this + +Starting with version 3.0, the GLU header `glu.h` is no longer included by +default. If you wish to include it, define `GLFW_INCLUDE_GLU` before the +inclusion of the GLFW header. + +@code +#define GLFW_INCLUDE_GLU +#include +@endcode + + +@subsection quick_init_term Initializing and terminating GLFW + +Before you can use most GLFW functions, the library must be initialized. On +successful initialization, `GL_TRUE` is returned. If an error occurred, +`GL_FALSE` is returned. + +@code +if (!glfwInit()) + exit(EXIT_FAILURE); +@endcode + +When you are done using GLFW, typically just before the application exits, you +need to terminate GLFW. + +@code +glfwTerminate(); +@endcode + +This destroys any remaining windows and releases any other resources allocated by +GLFW. After this call, you must initialize GLFW again before using any GLFW +functions that require it. + + +@subsection quick_capture_error Setting an error callback + +Most events are reported through callbacks, whether it's a key being pressed, +a GLFW window being moved, or an error occurring. Callbacks are simply +C functions (or C++ static methods) that are called by GLFW with arguments +describing the event. + +In case a GLFW function fails, an error is reported to the GLFW error callback. +You can receive these reports with an error callback. This function must have +the signature below. This simple error callback just prints the error +description to `stderr`. + +@code +void error_callback(int error, const char* description) +{ + fputs(description, stderr); +} +@endcode + +Callback functions must be set, so GLFW knows to call them. The function to set +the error callback is one of the few GLFW functions that may be called before +initialization, which lets you be notified of errors both during and after +initialization. + +@code +glfwSetErrorCallback(error_callback); +@endcode + + +@subsection quick_create_window Creating a window and context + +The window and its OpenGL context are created with a single call, which returns +a handle to the created combined window and context object. For example, this +creates a 640 by 480 windowed mode window with an OpenGL context: + +@code +GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL); +@endcode + +If window or context creation fails, `NULL` will be returned, so it is necessary +to check the return value. + +@code +if (!window) +{ + glfwTerminate(); + exit(EXIT_FAILURE); +} +@endcode + +The window handle is passed to all window related functions and is provided to +along to all window related callbacks, so they can tell which window received +the event. + +When a window is no longer needed, destroy it. + +@code +glfwDestroyWindow(window); +@endcode + +Once this function is called, no more events will be delivered for that window +and its handle becomes invalid. + + +@subsection quick_context_current Making the OpenGL context current + +Before you can use the OpenGL API, you must have a current OpenGL context. + +@code +glfwMakeContextCurrent(window); +@endcode + +The context will remain current until you make another context current or until +the window owning the current context is destroyed. + + +@subsection quick_window_close Checking the window close flag + +Each window has a flag indicating whether the window should be closed. + +When the user attempts to close the window, either by pressing the close widget +in the title bar or using a key combination like Alt+F4, this flag is set to 1. +Note that __the window isn't actually closed__, so you are expected to monitor +this flag and either destroy the window or give some kind of feedback to the +user. + +@code +while (!glfwWindowShouldClose(window)) +{ + // Keep running +} +@endcode + +You can be notified when the user is attempting to close the window by setting +a close callback with @ref glfwSetWindowCloseCallback. The callback will be +called immediately after the close flag has been set. + +You can also set it yourself with @ref glfwSetWindowShouldClose. This can be +useful if you want to interpret other kinds of input as closing the window, like +for example pressing the escape key. + + +@subsection quick_key_input Receiving input events + +Each window has a large number of callbacks that can be set to receive all the +various kinds of events. To receive key press and release events, create a key +callback function. + +@code +static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) +{ + if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS) + glfwSetWindowShouldClose(window, GL_TRUE); +} +@endcode + +The key callback, like other window related callbacks, are set per-window. + +@code +glfwSetKeyCallback(window, key_callback); +@endcode + +In order for event callbacks to be called when events occur, you need to process +events as described below. + + +@subsection quick_render Rendering with OpenGL + +Once you have a current OpenGL context, you can use OpenGL normally. In this +tutorial, a multi-colored rotating triangle will be rendered. The framebuffer +size needs to be retrieved for `glViewport`. + +@code +int width, height; +glfwGetFramebufferSize(window, &width, &height); +glViewport(0, 0, width, height); +@endcode + +You can also set a framebuffer size callback using @ref +glfwSetFramebufferSizeCallback and call `glViewport` from there. + + +@subsection quick_timer Reading the timer + +To create smooth animation, a time source is needed. GLFW provides a timer that +returns the number of seconds since initialization. The time source used is the +most accurate on each platform and generally has micro- or nanosecond +resolution. + +@code +double time = glfwGetTime(); +@endcode + + +@subsection quick_swap_buffers Swapping buffers + +GLFW windows by default use double buffering. That means that each window has +two rendering buffers; a front buffer and a back buffer. The front buffer is +the one being displayed and the back buffer the one you render to. + +When the entire frame has been rendered, the buffers need to be swapped with one +another, so the back buffer becomes the front buffer and vice versa. + +@code +glfwSwapBuffers(window); +@endcode + +The swap interval indicates how many frames to wait until swapping the buffers, +commonly known as _vsync_. By default, the swap interval is zero, meaning +buffer swapping will occur immediately. On fast machines, many of those frames +will never be seen, as the screen is still only updated typically 60-75 times +per second, so this wastes a lot of CPU and GPU cycles. + +Also, because the buffers will be swapped in the middle the screen update, +leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing). + +For these reasons, applications will typically want to set the swap interval to +one. It can be set to higher values, but this is usually not recommended, +because of the input latency it leads to. + +@code +glfwSwapInterval(1); +@endcode + +This function acts on the current context and will fail unless a context is +current. + + +@subsection quick_process_events Processing events + +GLFW needs to communicate regularly with the window system both in order to +receive events and to show that the application hasn't locked up. Event +processing must be done regularly while you have visible windows and is normally +done each frame after buffer swapping. + +There are two methods for processing pending events; polling and waiting. This +example will use event polling, which processes only those events that have +already been received and then returns immediately. + +@code +glfwPollEvents(); +@endcode + +This is the best choice when rendering continually, like most games do. If +instead you only need to update your rendering once you have received new input, +@ref glfwWaitEvents is a better choice. It waits until at least one event has +been received, putting the thread to sleep in the meantime, and then processes +all received events. This saves a great deal of CPU cycles and is useful for, +for example, many kinds of editing tools. + + +@section quick_example Putting it together + +Now that you know how to initialize GLFW, create a window and poll for +keyboard input, it's possible to create a simple program. + +@snippet simple.c code + +This program creates a 640 by 480 windowed mode window and starts a loop that +clears the screen, renders a triangle and processes events until the user either +presses Escape or closes the window. + +This program uses only a few of the many functions GLFW provides.

That is, if you have compiled GLFW then you have already built this +as `simple.exe` on Windows, `simple` on Linux or `simple.app` on OS X. + +This tutorial ends here.

This can be useful if you need to set up +your window further before showing it, for example moving it to a specific +location. + +You can also get the current visibility state with @ref glfwGetWindowAttrib. + +@code +int visible = glfwGetWindowAttrib(window, GLFW_VISIBLE); +@endcode + + +@subsection window_focus Window input focus + +If you wish to be notified when a window gains or loses input focus, whether by +the user, system or your own code, set a focus callback. + +@code +glfwSetWindowFocusCallback(window, window_focus_callback); +@endcode + +The callback function receives changes in the input focus state of the window. + +@code +void window_focus_callback(GLFWwindow* window, int focused) +{ + if (focused) + { + // The window gained input focus + } + else + { + // The window lost input focus + } +} +@endcode + +You can also get the current input focus state with @ref glfwGetWindowAttrib. + +@code +int focused = glfwGetWindowAttrib(window, GLFW_FOCUSED); +@endcode + + +@subsection window_refresh Window damage and refresh + +If you wish to be notified when the contents of a window is damaged and needs +to be refreshed, set a window refresh callback. + +@code +glfwSetWindowRefreshCallback(m_handle, window_refresh_callback); +@endcode + +The callback function is called when the contents of the window needs to be +refreshed. + +@code +void window_refresh_callback(GLFWwindow* window) +{ + draw_editor_ui(window); + glfwSwapBuffers(window); +} +@endcode + +@note On compositing window systems such as Aero, Compiz or Aqua, where the +window contents are saved off-screen, this callback might only be called when +the window or framebuffer is resized. + + +@subsection window_attribs Window attributes + +Windows have a number of attributes that can be returned using @ref +glfwGetWindowAttrib. Some reflect state that may change during the lifetime of +the window, while others reflect the corresponding hints and are fixed at the +time of creation. Some are related to the actual window and others to its +context. + +@code +if (glfwGetWindowAttrib(window, GLFW_FOCUSED)) +{ + // window has input focus +} +@endcode + + +@subsubsection window_attribs_wnd Window related attributes + +`GLFW_FOCUSED` indicates whether the specified window has input focus. Initial +input focus is controlled by the [window hint](@ref window_hints_wnd) with the +same name. + +`GLFW_ICONIFIED` indicates whether the specified window is iconified, whether by +the user or with @ref glfwIconifyWindow. + +`GLFW_VISIBLE` indicates whether the specified window is visible. Window +visibility can be controlled with @ref glfwShowWindow and @ref glfwHideWindow +and initial visibility is controlled by the [window hint](@ref window_hints_wnd) +with the same name. + +`GLFW_RESIZABLE` indicates whether the specified window is resizable _by the +user_. This is set on creation with the [window hint](@ref window_hints_wnd) + with the same name. + +`GLFW_DECORATED` indicates whether the specified window has decorations such as +a border, a close widget, etc. This is set on creation with the +[window hint](@ref window_hints_wnd) with the same name. + +`GLFW_FLOATING` indicates whether the specified window is floating, also called +topmost or always-on-top. This is controlled by the +[window hint](@ref window_hints_wnd) with the same name. + + +@subsubsection window_attribs_ctx Context related attributes + +`GLFW_CLIENT_API` indicates the client API provided by the window's context; +either `GLFW_OPENGL_API` or `GLFW_OPENGL_ES_API`. + +`GLFW_CONTEXT_VERSION_MAJOR`, `GLFW_CONTEXT_VERSION_MINOR` and +`GLFW_CONTEXT_REVISION` indicate the client API version of the window's context. + +`GLFW_OPENGL_FORWARD_COMPAT` is `GL_TRUE` if the window's context is an OpenGL +forward-compatible one, or `GL_FALSE` otherwise. + +`GLFW_OPENGL_DEBUG_CONTEXT` is `GL_TRUE` if the window's context is an OpenGL +debug context, or `GL_FALSE` otherwise. + +`GLFW_OPENGL_PROFILE` indicates the OpenGL profile used by the context. This is +`GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context uses +a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is unknown +or the context is an OpenGL ES context. Note that the returned profile may not +match the profile bits of the context flags, as GLFW will try other means of +detecting the profile when no bits are set. + +`GLFW_CONTEXT_ROBUSTNESS` indicates the robustness strategy used by the context. +This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION` if the +window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise. + + +@section buffer_swap Buffer swapping + +GLFW windows are by default double buffered. That means that you have two +rendering buffers; a front buffer and a back buffer. The front buffer is +the one being displayed and the back buffer the one you render to. + +When the entire frame has been rendered, it is time to swap the back and the +front buffers in order to display what has been rendered and begin rendering +a new frame. This is done with @ref glfwSwapBuffers. + +@code +glfwSwapBuffers(window); +@endcode + +Sometimes it can be useful to select when the buffer swap will occur. With the +function @ref glfwSwapInterval it is possible to select the minimum number of +monitor refreshes the driver wait should from the time @ref glfwSwapBuffers was +called before swapping the buffers: + +@code +glfwSwapInterval(1); +@endcode + +If the interval is zero, the swap will take place immediately when @ref +glfwSwapBuffers is called without waiting for a refresh. Otherwise at least +interval retraces will pass between each buffer swap. Using a swap interval of +zero can be useful for benchmarking purposes, when it is not desirable to +measure the time it takes to wait for the vertical retrace. However, a swap +interval of one lets you avoid tearing. + +Note that this may not work on all machines, as some drivers have +user-controlled settings that override any swap interval the application +requests. It is also by default disabled on Windows Vista and later when using +DWM (Aero), as using it there sometimes leads to severe jitter. You can +forcibly enable it for machines using DWM using @ref compile_options_win32. + +*/ diff --git a/testbed/glfw/examples/CMakeLists.txt b/testbed/glfw/examples/CMakeLists.txt new file mode 100644 index 00000000..229c4a72 --- /dev/null +++ b/testbed/glfw/examples/CMakeLists.txt @@ -0,0 +1,80 @@ + +link_libraries(glfw "${OPENGL_glu_LIBRARY}") + +if (BUILD_SHARED_LIBS) + add_definitions(-DGLFW_DLL) + link_libraries("${OPENGL_gl_LIBRARY}" "${MATH_LIBRARY}") +else() + link_libraries(${glfw_LIBRARIES}) +endif() + +include_directories("${GLFW_SOURCE_DIR}/include" + "${GLFW_SOURCE_DIR}/deps") + +if ("${OPENGL_INCLUDE_DIR}") + include_directories("${OPENGL_INCLUDE_DIR}") +endif() + +set(GLAD "${GLFW_SOURCE_DIR}/deps/glad/glad.h" + "${GLFW_SOURCE_DIR}/deps/glad.c") +set(GETOPT "${GLFW_SOURCE_DIR}/deps/getopt.h" + "${GLFW_SOURCE_DIR}/deps/getopt.c") +set(TINYCTHREAD "${GLFW_SOURCE_DIR}/deps/tinycthread.h" + "${GLFW_SOURCE_DIR}/deps/tinycthread.c") + +if (APPLE) + # Set fancy names for bundles + add_executable(Boing MACOSX_BUNDLE boing.c) + add_executable(Gears MACOSX_BUNDLE gears.c) + add_executable(Heightmap MACOSX_BUNDLE heightmap.c ${GLAD}) + add_executable(Particles MACOSX_BUNDLE particles.c ${TINYCTHREAD}) + add_executable(Simple MACOSX_BUNDLE simple.c) + add_executable(SplitView MACOSX_BUNDLE splitview.c) + add_executable(Wave MACOSX_BUNDLE wave.c) + + set_target_properties(Boing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Boing") + set_target_properties(Gears PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Gears") + set_target_properties(Heightmap PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Heightmap") + set_target_properties(Particles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Particles") + set_target_properties(Simple PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Simple") + set_target_properties(SplitView PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Split View") + set_target_properties(Wave PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Wave") + + set_target_properties(Boing Gears Heightmap Particles Simple SplitView Wave PROPERTIES + FOLDER "GLFW3/Examples") +else() + # Set boring names for executables + add_executable(boing WIN32 boing.c) + add_executable(gears WIN32 gears.c) + add_executable(heightmap WIN32 heightmap.c ${GLAD}) + add_executable(particles WIN32 particles.c ${TINYCTHREAD} ${GETOPT}) + add_executable(simple WIN32 simple.c) + add_executable(splitview WIN32 splitview.c) + add_executable(wave WIN32 wave.c) + + set_target_properties(boing gears heightmap particles simple splitview wave PROPERTIES + FOLDER "GLFW3/Examples") +endif() + +if (APPLE) + target_link_libraries(Particles "${CMAKE_THREAD_LIBS_INIT}") +elseif (UNIX) + target_link_libraries(particles "${CMAKE_THREAD_LIBS_INIT}" "${RT_LIBRARY}") +endif() + +if (MSVC) + set(WINDOWS_BINARIES boing gears heightmap particles simple splitview wave) + + # Tell MSVC to use main instead of WinMain for Windows subsystem executables + set_target_properties(${WINDOWS_BINARIES} PROPERTIES + LINK_FLAGS "/ENTRY:mainCRTStartup") +endif() + +if (APPLE) + set(BUNDLE_BINARIES Boing Gears Heightmap Particles Simple SplitView Wave) + + set_target_properties(${BUNDLE_BINARIES} PROPERTIES + MACOSX_BUNDLE_SHORT_VERSION_STRING ${GLFW_VERSION} + MACOSX_BUNDLE_LONG_VERSION_STRING ${GLFW_VERSION_FULL}) +endif() + diff --git a/testbed/glfw/examples/boing.c b/testbed/glfw/examples/boing.c new file mode 100644 index 00000000..ec313596 --- /dev/null +++ b/testbed/glfw/examples/boing.c @@ -0,0 +1,669 @@ +/***************************************************************************** + * Title: GLBoing + * Desc: Tribute to Amiga Boing. + * Author: Jim Brooks + * Original Amiga authors were R.J.

See -@ref buffer_swap. - - -@section context_glext OpenGL and OpenGL ES extensions - -One of the benefits of OpenGL and OpenGL ES are their extensibility. -Hardware vendors may include extensions in their implementations that extend the -API before that functionality is included in a new version of the OpenGL or -OpenGL ES specification, and some extensions are never included and remain -as extensions until they become obsolete. - -An extension is defined by: - -- An extension name (e.g. `GL_ARB_debug_output`) -- New OpenGL tokens (e.g. `GL_DEBUG_SEVERITY_HIGH_ARB`) -- New OpenGL functions (e.g. `glGetDebugMessageLogARB`) - -Note the `ARB` affix, which stands for Architecture Review Board and is used -for official extensions. The extension above was created by the ARB, but there -are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD. Any -group may also use the generic `EXT` affix. Lists of extensions, together with -their specifications, can be found at the -[OpenGL Registry](http://www.opengl.org/registry/) and -[OpenGL ES Registry](https://www.khronos.org/registry/gles/). - - -@subsection context_glext_auto Loading extension with a loader library - -An extension loader library is the easiest and best way to access both OpenGL and -OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. -They will take care of all the details of declaring and loading everything you -need. One such library is [glad](https://github.com/Dav1dde/glad) and there are -several others. - -The following example will use glad but all extension loader libraries work -similarly. - -First you need to generate the source files using the glad Python script. This -example generates a loader for any version of OpenGL, which is the default for -both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific -API versions and extension sets can be generated. The generated files are -written to the `output` directory. - -@code{.sh} -python main.py --generator c --no-loader --out-path output -@endcode - -The `--no-loader` option is added because GLFW already provides a function for -loading OpenGL and OpenGL ES function pointers and glad can call this instead of -having to implement its own. There are several other command-line options as -well. See the glad documentation for details. - -Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and -`output/include/KHR/khrplatform.h` files to your build. Then you need to -include the glad header file, which will replace the OpenGL header of your -development environment. By including the glad header before the GLFW header, -it suppresses the development environment's OpenGL or OpenGL ES header. - -@code -#include -#include -@endcode - -Finally you need to initialize glad once you have a suitable current context. - -@code -window = glfwCreateWindow(640, 480, "My Window", NULL, NULL); -if (!window) -{ - ... -} - -glfwMakeContextCurrent(window); - -gladLoadGLLoader((GLADloadproc) glfwGetProcAddress); -@endcode - -Once glad has been loaded, you have access to all OpenGL core and extension -functions supported by both the context you created and the glad loader you -generated and you are ready to start rendering. - -You can specify a minimum required OpenGL or OpenGL ES version with -[context hints](@ref window_hints_ctx). If your needs are more complex, you can -check the actual OpenGL or OpenGL ES version with -[context attributes](@ref window_attribs_ctx), or you can check whether -a specific version is supported by the current context with the -`GLAD_GL_VERSION_x_x` booleans. - -@code -if (GLAD_GL_VERSION_3_2) -{ - // Call OpenGL 3.2+ specific code -} -@endcode - -To check whether a specific extension is supported, use the `GLAD_GL_xxx` -booleans. - -@code -if (GLAD_GL_ARB_debug_output) -{ - // Use GL_ARB_debug_output -} -@endcode - - -@subsection context_glext_manual Loading extensions manually - -__Do not use this technique__ unless it is absolutely necessary. An -[extension loader library](@ref context_glext_auto) will save you a ton of -tedious, repetitive, error prone work. - -To use a certain extension, you must first check whether the context supports -that extension and then, if it introduces new functions, retrieve the pointers -to those functions. GLFW provides @ref glfwExtensionSupported and @ref -glfwGetProcAddress for manual loading of extensions and new API functions. - -This section will demonstrate manual loading of OpenGL extensions. The loading -of OpenGL ES extensions is identical except for the name of the extension header. - - -@subsubsection context_glext_header The glext.h header - -The `glext.h` extension header is a continually updated file that defines the -interfaces for all OpenGL extensions. The latest version of this can always be -found at the [OpenGL Registry](http://www.opengl.org/registry/). There are also -extension headers for the various versions of OpenGL ES at the -[OpenGL ES Registry](https://www.khronos.org/registry/gles/). It it strongly -recommended that you use your own copy of the extension header, as the one -included in your development environment may be several years out of date and -may not include the extensions you wish to use. - -The header defines function pointer types for all functions of all extensions it -supports. These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for -`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer -to function) and `PROC` (procedure) are added to the ends. - -To include the extension header, define [GLFW_INCLUDE_GLEXT](@ref build_macros) -before including the GLFW header. - -@code -#define GLFW_INCLUDE_GLEXT -#include -@endcode - - -@subsubsection context_glext_string Checking for extensions - -A given machine may not actually support the extension (it may have older -drivers or a graphics card that lacks the necessary hardware features), so it -is necessary to check at run-time whether the context supports the extension. -This is done with @ref glfwExtensionSupported. - -@code -if (glfwExtensionSupported("GL_ARB_debug_output")) -{ - // The extension is supported by the current context -} -@endcode - -The argument is a null terminated ASCII string with the extension name. If the -extension is supported, @ref glfwExtensionSupported returns `GL_TRUE`, otherwise -it returns `GL_FALSE`. - - -@subsubsection context_glext_proc Fetching function pointers - -Many extensions, though not all, require the use of new OpenGL functions. -These functions often do not have entry points in the client API libraries of -your operating system, making it necessary to fetch them at run time. You can -retrieve pointers to these functions with @ref glfwGetProcAddress. - -@code -PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB"); -@endcode - -In general, you should avoid giving the function pointer variables the (exact) -same name as the function, as this may confuse your linker. Instead, you can -use a different prefix, like above, or some other naming scheme. - -Now that all the pieces have been introduced, here is what they might look like -when used together. - -@code -#define GLFW_INCLUDE_GLEXT -#include - -#define glGetDebugMessageLogARB pfnGetDebugMessageLog -PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog; - -// Flag indicating whether the extension is supported -int has_ARB_debug_output = 0; - -void load_extensions(void) -{ - if (glfwExtensionSupported("GL_ARB_debug_output")) - { - pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC) glfwGetProcAddress("glGetDebugMessageLogARB"); - if (pfnGetDebugMessageLog) - { - // Both the extension name and the function pointer are present - has_ARB_debug_output = 1; - } - } -} - -void some_function(void) -{ - if (has_ARB_debug_output) - { - // Now the extension function can be called as usual - glGetDebugMessageLogARB(...); - } -} -@endcode - -*/ diff --git

There are also -guides for the other areas of GLFW. - - - @ref intro - - @ref window - - @ref context - - @ref monitor - -GLFW provides many kinds of input. While some can only be polled, like time, or -only received via callbacks, like scrolling, there are those that provide both -callbacks and polling. Where a callback is provided, that is the recommended -way to receive that kind of input. The more you can use callbacks the less time -your users' machines will need to spend polling. - -All input callbacks receive a window handle. By using the -[window user pointer](@ref window_userptr), you can access non-global structures -or objects from your callbacks. - -To get a better feel for how the various events callbacks behave, run the -`events` test program. It register every callback supported by GLFW and prints -out all arguments provided for every event, along with time and sequence -information. - - -@section events Event processing - -GLFW needs to communicate regularly with the window system both in order to -receive events and to show that the application hasn't locked up. Event -processing must be done regularly while you have visible windows and is normally -done each frame after [buffer swapping](@ref buffer_swap). - -There are two functions for processing pending events. @ref glfwPollEvents, -processes only those events that have already been received and then returns -immediately. - -@code -glfwPollEvents(); -@endcode - -This is the best choice when rendering continually, like most games do. - -If you only need to update the contents of the window when you receive new -input, @ref glfwWaitEvents is a better choice. - -@code -glfwWaitEvents(); -@endcode - -It puts the thread to sleep until at least one event has been received and then -processes all received events. This saves a great deal of CPU cycles and is -useful for, for example, editing tools. There must be at least one GLFW window -for this function to sleep. - -If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from -another thread by posting an empty event to the event queue with @ref -glfwPostEmptyEvent. - -@code -glfwPostEmptyEvent(); -@endcode - -Do not assume that callbacks will _only_ be called through either of the above -functions. While it is necessary to process events in the event queue, some -window systems will send some events directly to the application, which in turn -causes callbacks to be called outside of regular event processing. - - -@section input_keyboard Keyboard input - -GLFW divides keyboard input into two categories; key events and character -events. Key events relate to actual physical keyboard keys, whereas character -events relate to the Unicode code points generated by pressing some of them. - -Keys and characters do not map 1:1. A single key press may produce several -characters, and a single character may require several keys to produce. This -may not be the case on your machine, but your users are likely not all using the -same keyboard layout, input method or even operating system as you. - - -@subsection input_key Key input - -If you wish to be notified when a physical key is pressed or released or when it -repeats, set a key callback. - -@code -glfwSetKeyCallback(window, key_callback); -@endcode - -The callback function receives the [keyboard key](@ref keys), platform-specific -scancode, key action and [modifier bits](@ref mods). - -@code -void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) -{ - if (key == GLFW_KEY_E && action == GLFW_PRESS) - activate_airship(); -} -@endcode - -The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key -will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it.

Those keys will still have unique, if platform-specific -scancodes. - -Key states for [named keys](@ref keys) are also saved in per-window state arrays -that can be polled with @ref glfwGetKey. - -@code -int state = glfwGetKey(window, GLFW_KEY_E); -if (state == GLFW_PRESS) - activate_airship(); -@endcode - -The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -This function only returns cached key event state. It does not poll the -system for the current state of the key. - -Whenever you poll state, you risk missing the state change you are looking for. -If a pressed key is released again before you poll its state, you will have -missed the key press. The recommended solution for this is to use a -key callback, but there is also the `GLFW_STICKY_KEYS` input mode. - -@code -glfwSetInputMode(window, GLFW_STICKY_KEYS, 1); -@endcode - -When sticky keys mode is enabled, the pollable state of a key will remain -`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey.

Unlike key input, text input obeys keyboard -layouts and modifier keys and supports composing characters using -[dead keys](https://en.wikipedia.org/wiki/Dead_key).

By default, the cursor mode is `GLFW_CURSOR_NORMAL`, -meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor) -is used and cursor motion is not limited. - -If you wish to implement mouse motion based camera controls or other input -schemes that require unlimited mouse movement, set the cursor mode to -`GLFW_CURSOR_DISABLED`. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); -@endcode - -This will hide the cursor and lock it to the specified window. GLFW will then -take care of all the details of cursor re-centering and offset calculation and -providing the application with a virtual cursor position. This virtual position -is provided normally via both the cursor position callback and through polling. - -@note You should not implement your own version of this functionality using -other features of GLFW.

The pixels are -arranged canonically as sequential rows, starting from the top-left corner. - - -@subsubsection cursor_standard Standard cursor creation - -A cursor with a [standard shape](@ref shapes) from the current system cursor -theme can be can be created with @ref glfwCreateStandardCursor. - -@code -GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR); -@endcode - -These cursor objects behave in the exact same way as those created with @ref -glfwCreateCursor except that the system cursor theme provides the actual image. - - -@subsubsection cursor_destruction Cursor destruction - -When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor. - -@code -glfwDestroyCursor(cursor); -@endcode - -Cursor destruction always succeeds. All cursors remaining when @ref -glfwTerminate is called are destroyed as well. - - -@subsubsection cursor_set Cursor setting - -A cursor can be set as current for a window with @ref glfwSetCursor. - -@code -glfwSetCursor(window, cursor); -@endcode - -Once set, the cursor image will be used as long as the system cursor is over the -client area of the window and the [cursor mode](@ref cursor_mode) is set -to `GLFW_CURSOR_NORMAL`. - -A single cursor may be set for any number of windows. - -To remove a cursor from a window, set the cursor of that window to `NULL`. - -@code -glfwSetCursor(window, NULL); -@endcode - -When a cursor is destroyed, it is removed from any window where it is set. This -does not affect the cursor modes of those windows. - - -@subsection cursor_enter Cursor enter/leave events - -If you wish to be notified when the cursor enters or leaves the client area of -a window, set a cursor enter/leave callback. - -@code -glfwSetCursorEnterCallback(window, cursor_enter_callback); -@endcode - -The callback function receives the new classification of the cursor. - -@code -void cursor_enter_callback(GLFWwindow* window, int entered) -{ - if (entered) - { - // The cursor entered the client area of the window - } - else - { - // The cursor left the client area of the window - } -} -@endcode - - -@subsection input_mouse_button Mouse button input - -If you wish to be notified when a mouse button is pressed or released, set -a mouse button callback. - -@code -glfwSetMouseButtonCallback(window, mouse_button_callback); -@endcode - -The callback function receives the [mouse button](@ref buttons), button action -and [modifier bits](@ref mods). - -@code -void mouse_button_callback(GLFWwindow* window, int button, int action, int mods) -{ - if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS) - popup_menu(); -} -@endcode - -The action is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -Mouse button states for [named buttons](@ref buttons) are also saved in -per-window state arrays that can be polled with @ref glfwGetMouseButton. - -@code -int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT); -if (state == GLFW_PRESS) - upgrade_cow(); -@endcode - -The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -This function only returns cached mouse button event state. It does not poll -the system for the current state of the mouse button. - -Whenever you poll state, you risk missing the state change you are looking for. -If a pressed mouse button is released again before you poll its state, you will have -missed the button press. The recommended solution for this is to use a -mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS` -input mode. - -@code -glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, 1); -@endcode - -When sticky mouse buttons mode is enabled, the pollable state of a mouse button -will remain `GLFW_PRESS` until the state of that button is polled with @ref -glfwGetMouseButton. Once it has been polled, if a mouse button release event -had been processed in the meantime, the state will reset to `GLFW_RELEASE`, -otherwise it will remain `GLFW_PRESS`. - -The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any -[named button](@ref buttons). - - -@subsection scrolling Scroll input - -If you wish to be notified when the user scrolls, whether with a mouse wheel or -touchpad gesture, set a scroll callback. - -@code -glfwSetScrollCallback(window, scroll_callback); -@endcode - -The callback function receives two-dimensional scroll offsets. - -@code -void scroll_callback(GLFWwindow* window, double xoffset, double yoffset) -{ -} -@endcode - -A simple mouse wheel, being vertical, provides offsets along the Y-axis. - - -@section joystick Joystick input - -The joystick functions expose connected joysticks and controllers, with both -referred to as joysticks. It supports up to sixteen joysticks, ranging from -`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to `GLFW_JOYSTICK_LAST`. You can test -whether a [joystick](@ref joysticks) is present with @ref glfwJoystickPresent. - -@code -int present = glfwJoystickPresent(GLFW_JOYSTICK_1); -@endcode - -When GLFW is initialized, detected joysticks are added to to the beginning of -the array, starting with `GLFW_JOYSTICK_1`.

However, no GLFW function may be called from any other -thread until GLFW has been successfully initialized on the main thread, -including functions that may called before initialization. - -The reference documentation for every GLFW function states whether it is limited -to the main thread. - -The following categories of functions are and will remain limited to the main -thread due to the limitations of one or several platforms: - - - Initialization and termination - - Event processing - - Creation and destruction of window, context and cursor objects - -Because event processing must be performed on the main thread, all callbacks -except for the error callback will only be called on that thread. The error -callback may be called on any thread, as any GLFW function may generate errors. - -The posting of empty events may be done from any thread.

Note that @ref glfwGetKey still returns only `GLFW_PRESS` or -`GLFW_RELEASE`. - - -@subsection moving_keys Physical key input - -GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to -the values generated by the current keyboard layout. The tokens are named -according to the values they would have using the standard US layout, but this -is only a convenience, as most programmers are assumed to know that layout. -This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and -is the same key in the same place regardless of what keyboard layouts the users -of your program has. - -The key input facility was never meant for text input, although using it that -way worked slightly better in GLFW 2. If you were using it to input text, you -should be using the character callback instead, on both GLFW 2 and 3. This will -give you the characters being input, as opposed to the keys being pressed. - -GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of -having to remember whether to check for `'a'` or `'A'`, you now check for -`GLFW_KEY_A`. - - -@subsection moving_joystick Joystick function changes - -The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes. - -The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and -`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent -function as well as axis and button counts returned by the @ref -glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions. - - -@subsection moving_mbcs Win32 MBCS support - -The Win32 port of GLFW 3 will not compile in -[MBCS mode](http://msdn.microsoft.com/en-us/library/5z097dxa.aspx). -However, because the use of the Unicode version of the Win32 API doesn't affect -the process as a whole, but only those windows created using it, it's perfectly -possible to call MBCS functions from other parts of the same application. -Therefore, even if an application using GLFW has MBCS mode code, there's no need -for GLFW itself to support it. - - -@subsection moving_windows Support for versions of Windows older than XP - -All explicit support for version of Windows older than XP has been removed. -There is no code that actively prevents GLFW 3 from running on these earlier -versions, but it uses Win32 functions that those versions lack. - -Windows XP was released in 2001, and by now (January 2015) it has not only -replaced almost all earlier versions of Windows, but is itself rapidly being -replaced by Windows 7 and 8. The MSDN library doesn't even provide -documentation for version older than Windows 2000, making it difficult to -maintain compatibility with these versions even if it was deemed worth the -effort. - -The Win32 API has also not stood still, and GLFW 3 uses many functions only -present on Windows XP or later.

That means that each window has -two rendering buffers; a front buffer and a back buffer.

Event -processing must be done regularly while you have visible windows and is normally -done each frame after buffer swapping. - -There are two methods for processing pending events; polling and waiting. This -example will use event polling, which processes only those events that have -already been received and then returns immediately. - -@code -glfwPollEvents(); -@endcode - -This is the best choice when rendering continually, like most games do. If -instead you only need to update your rendering once you have received new input, -@ref glfwWaitEvents is a better choice. It waits until at least one event has -been received, putting the thread to sleep in the meantime, and then processes -all received events.

Initial -input focus is controlled by the [window hint](@ref window_hints_wnd) with the -same name. - -`GLFW_ICONIFIED` indicates whether the specified window is iconified, whether by -the user or with @ref glfwIconifyWindow. - -`GLFW_VISIBLE` indicates whether the specified window is visible. Window -visibility can be controlled with @ref glfwShowWindow and @ref glfwHideWindow -and initial visibility is controlled by the [window hint](@ref window_hints_wnd) -with the same name. - -`GLFW_RESIZABLE` indicates whether the specified window is resizable _by the -user_. This is set on creation with the [window hint](@ref window_hints_wnd) - with the same name. - -`GLFW_DECORATED` indicates whether the specified window has decorations such as -a border, a close widget, etc. This is set on creation with the -[window hint](@ref window_hints_wnd) with the same name. - -`GLFW_FLOATING` indicates whether the specified window is floating, also called -topmost or always-on-top. This is controlled by the -[window hint](@ref window_hints_wnd) with the same name. - - -@subsubsection window_attribs_ctx Context related attributes - -`GLFW_CLIENT_API` indicates the client API provided by the window's context; -either `GLFW_OPENGL_API` or `GLFW_OPENGL_ES_API`. - -`GLFW_CONTEXT_VERSION_MAJOR`, `GLFW_CONTEXT_VERSION_MINOR` and -`GLFW_CONTEXT_REVISION` indicate the client API version of the window's context. - -`GLFW_OPENGL_FORWARD_COMPAT` is `GL_TRUE` if the window's context is an OpenGL -forward-compatible one, or `GL_FALSE` otherwise. - -`GLFW_OPENGL_DEBUG_CONTEXT` is `GL_TRUE` if the window's context is an OpenGL -debug context, or `GL_FALSE` otherwise. - -`GLFW_OPENGL_PROFILE` indicates the OpenGL profile used by the context. This is -`GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context uses -a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is unknown -or the context is an OpenGL ES context. Note that the returned profile may not -match the profile bits of the context flags, as GLFW will try other means of -detecting the profile when no bits are set. - -`GLFW_CONTEXT_ROBUSTNESS` indicates the robustness strategy used by the context. -This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION` if the -window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise. - - -@section buffer_swap Buffer swapping - -GLFW windows are by default double buffered. That means that you have two -rendering buffers; a front buffer and a back buffer. The front buffer is -the one being displayed and the back buffer the one you render to. - -When the entire frame has been rendered, it is time to swap the back and the -front buffers in order to display what has been rendered and begin rendering -a new frame. This is done with @ref glfwSwapBuffers. - -@code -glfwSwapBuffers(window); -@endcode - -Sometimes it can be useful to select when the buffer swap will occur. With the -function @ref glfwSwapInterval it is possible to select the minimum number of -monitor refreshes the driver wait should from the time @ref glfwSwapBuffers was -called before swapping the buffers: - -@code -glfwSwapInterval(1); -@endcode - -If the interval is zero, the swap will take place immediately when @ref -glfwSwapBuffers is called without waiting for a refresh. Otherwise at least -interval retraces will pass between each buffer swap. Using a swap interval of -zero can be useful for benchmarking purposes, when it is not desirable to -measure the time it takes to wait for the vertical retrace. However, a swap -interval of one lets you avoid tearing. - -Note that this may not work on all machines, as some drivers have -user-controlled settings that override any swap interval the application -requests. It is also by default disabled on Windows Vista and later when using -DWM (Aero), as using it there sometimes leads to severe jitter. You can -forcibly enable it for machines using DWM using @ref compile_options_win32. - -*/ diff --git a/examples/common/glfw/examples/CMakeLists.txt b/examples/common/glfw/examples/CMakeLists.txt deleted file mode 100644 index 229c4a72..00000000 --- a/examples/common/glfw/examples/CMakeLists.txt +++ /dev/null @@ -1,80 +0,0 @@ - -link_libraries(glfw "${OPENGL_glu_LIBRARY}") - -if (BUILD_SHARED_LIBS) - add_definitions(-DGLFW_DLL) - link_libraries("${OPENGL_gl_LIBRARY}" "${MATH_LIBRARY}") -else() - link_libraries(${glfw_LIBRARIES}) -endif() - -include_directories("${GLFW_SOURCE_DIR}/include" - "${GLFW_SOURCE_DIR}/deps") - -if ("${OPENGL_INCLUDE_DIR}") - include_directories("${OPENGL_INCLUDE_DIR}") -endif() - -set(GLAD "${GLFW_SOURCE_DIR}/deps/glad/glad.h" - "${GLFW_SOURCE_DIR}/deps/glad.c") -set(GETOPT "${GLFW_SOURCE_DIR}/deps/getopt.h" - "${GLFW_SOURCE_DIR}/deps/getopt.c") -set(TINYCTHREAD "${GLFW_SOURCE_DIR}/deps/tinycthread.h" - "${GLFW_SOURCE_DIR}/deps/tinycthread.c") - -if (APPLE) - # Set fancy names for bundles - add_executable(Boing MACOSX_BUNDLE boing.c) - add_executable(Gears MACOSX_BUNDLE gears.c) - add_executable(Heightmap MACOSX_BUNDLE heightmap.c ${GLAD}) - add_executable(Particles MACOSX_BUNDLE particles.c ${TINYCTHREAD}) - add_executable(Simple MACOSX_BUNDLE simple.c) - add_executable(SplitView MACOSX_BUNDLE splitview.c) - add_executable(Wave MACOSX_BUNDLE wave.c) - - set_target_properties(Boing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Boing") - set_target_properties(Gears PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Gears") - set_target_properties(Heightmap PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Heightmap") - set_target_properties(Particles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Particles") - set_target_properties(Simple PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Simple") - set_target_properties(SplitView PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Split View") - set_target_properties(Wave PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Wave") - - set_target_properties(Boing Gears Heightmap Particles Simple SplitView Wave PROPERTIES - FOLDER "GLFW3/Examples") -else() - # Set boring names for executables - add_executable(boing WIN32 boing.c) - add_executable(gears WIN32 gears.c) - add_executable(heightmap WIN32 heightmap.c ${GLAD}) - add_executable(particles WIN32 particles.c ${TINYCTHREAD} ${GETOPT}) - add_executable(simple WIN32 simple.c) - add_executable(splitview WIN32 splitview.c) - add_executable(wave WIN32 wave.c) - - set_target_properties(boing gears heightmap particles simple splitview wave PROPERTIES - FOLDER "GLFW3/Examples") -endif() - -if (APPLE) - target_link_libraries(Particles "${CMAKE_THREAD_LIBS_INIT}") -elseif (UNIX) - target_link_libraries(particles "${CMAKE_THREAD_LIBS_INIT}" "${RT_LIBRARY}") -endif() - -if (MSVC) - set(WINDOWS_BINARIES boing gears heightmap particles simple splitview wave) - - # Tell MSVC to use main instead of WinMain for Windows subsystem executables - set_target_properties(${WINDOWS_BINARIES} PROPERTIES - LINK_FLAGS "/ENTRY:mainCRTStartup") -endif() - -if (APPLE) - set(BUNDLE_BINARIES Boing Gears Heightmap Particles Simple SplitView Wave) - - set_target_properties(${BUNDLE_BINARIES} PROPERTIES - MACOSX_BUNDLE_SHORT_VERSION_STRING ${GLFW_VERSION} - MACOSX_BUNDLE_LONG_VERSION_STRING ${GLFW_VERSION_FULL}) -endif() - diff --git a/examples/common/glfw/examples/boing.c b/examples/common/glfw/examples/boing.c deleted file mode 100644 index ec313596..00000000 --- a/examples/common/glfw/examples/boing.c +++ /dev/null @@ -1,669 +0,0 @@ -/***************************************************************************** - * Title: GLBoing - * Desc: Tribute to Amiga Boing. - * Author: Jim Brooks - * Original Amiga authors were R.J.

A primer on the use of labels/IDs in ImGui.. + + - Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget). + to do so they need an unique ID. unique ID are typically derived from a string label, an integer index or a pointer. + + Button("OK"); // Label = "OK", ID = hash of "OK" + Button("Cancel"); // Label = "Cancel", ID = hash of "Cancel" + + - Elements that are not clickable, such as Text() items don't need an ID. + + - ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" in two different windows + or in two different locations of a tree. + + - if you have a same ID twice in the same location, you'll have a conflict: + + Button("OK"); + Button("OK"); // ID collision! Both buttons will be treated as the same. + + Fear not! this is easy to solve and there are many ways to solve it! + + - when passing a label you can optionally specify extra unique ID information within string itself. This helps solving the simpler collision cases. + use "##" to pass a complement to the ID that won't be visible to the end-user: + + Button("Play##0"); // Label = "Play", ID = hash of "Play##0" + Button("Play##1"); // Label = "Play", ID = hash of "Play##1" (different from above) + + - occasionally (rarely) you might want change a label while preserving a constant ID. This allows you to animate labels. + use "###" to pass a label that isn't part of ID: + + Button("Hello###ID"; // Label = "Hello", ID = hash of "ID" + Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above) + + - use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window. + this is the most convenient way of distinguish ID if you are iterating and creating many UI elements. + you can push a pointer, a string or an integer value. remember that ID are formed from the addition of everything in the ID stack! + + for (int i = 0; i < 100; i++) + { + PushID(i); + Button("Click"); // Label = "Click", ID = hash of integer + "label" (unique) + PopID(); + } + + for (int i = 0; i < 100; i++) + { + MyObject* obj = Objects[i]; + PushID(obj); + Button("Click"); // Label = "Click", ID = hash of pointer + "label" (unique) + PopID(); + } + + for (int i = 0; i < 100; i++) + { + MyObject* obj = Objects[i]; + PushID(obj->Name); + Button("Click"); // Label = "Click", ID = hash of string + "label" (unique) + PopID(); + } + + - more example showing that you can stack multiple prefixes into the ID stack: + + Button("Click"); // Label = "Click", ID = hash of "Click" + PushID("node"); + Button("Click"); // Label = "Click", ID = hash of "node" + "Click" + PushID(my_ptr); + Button("Click"); // Label = "Click", ID = hash of "node" + ptr + "Click" + PopID(); + PopID(); + + - tree nodes implicitly creates a scope for you by calling PushID(). + + Button("Click"); // Label = "Click", ID = hash of "Click" + if (TreeNode("node")) + { + Button("Click"); // Label = "Click", ID = hash of "node" + "Click" + TreePop(); + } + + - when working with trees, ID are used to preserve the opened/closed state of each tree node. + depending on your use cases you may want to use strings, indices or pointers as ID. + e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change. + e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense! + + Q: How do I update to a newer version of ImGui? + A: Overwrite the following files: + imgui.cpp + imgui.h + stb_rect_pack.h + stb_textedit.h + stb_truetype.h + Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. + + Q: Why is my text output blurry? + A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f) + + Q: How can I load a different font than the default?

You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit.

Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since they different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// ADVANCED USAGE +// +// Quality: +// +// - Use the functions with Subpixel at the end to allow your characters +// to have subpixel positioning. Since the font is anti-aliased, not +// hinted, this is very import for quality. (This is not possible with +// baked fonts.) +// +// - Kerning is now supported, and if you're supporting subpixel rendering +// then kerning is worth using to give your text a polished look. +// +// Performance: +// +// - Convert Unicode codepoints to glyph indexes and operate on the glyphs; +// if you don't do this, stb_truetype is forced to do the conversion on +// every call. +// +// - There are a lot of memory allocations. We should modify it to take +// a temp buffer and allocate from the temp buffer (without freeing), +// should help performance a lot. +// +// NOTES +// +// The system uses the raw data found in the .ttf file without changing it +// and without building auxiliary data structures. This is a bit inefficient +// on little-endian systems (the data is big-endian), but assuming you're +// caching the bitmaps or glyph shapes this shouldn't be a big deal. +// +// It appears to be very hard to programmatically determine what font a +// given file is in a general way.

Some of the weaknesses includes: - - doesn't look fancy, doesn't animate - - limited layout features, intricate layouts are typically crafted in code - - occasionally uses statically sized buffers for string manipulations - won't crash, but some very long pieces of text may be clipped. functions like ImGui::TextUnformatted() don't have such restriction. - - - END-USER GUIDE - ============== - - - double-click title bar to collapse window - - click upper right corner to close a window, available when 'bool* p_opened' is passed to ImGui::Begin() - - click and drag on lower right corner to resize window - - click and drag on any empty space to move window - - double-click/double-tap on lower right corner grip to auto-fit to content - - TAB/SHIFT+TAB to cycle through keyboard editable fields - - use mouse wheel to scroll - - use CTRL+mouse wheel to zoom window contents (if IO.FontAllowScaling is true) - - CTRL+Click on a slider to input value as text - - text editor: - - Hold SHIFT or use mouse to select text. - - CTRL+Left/Right to word jump - - CTRL+Shift+Left/Right to select words - - CTRL+A our Double-Click to select all - - CTRL+X,CTRL+C,CTRL+V to use OS clipboard - - CTRL+Z,CTRL+Y to undo/redo - - ESCAPE to revert text to its original value - - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!) - - - PROGRAMMER GUIDE - ================ - - - read the FAQ below this section! - - your code creates the UI, if your code doesn't run the UI is gone! == very dynamic UI, no construction/destructions steps, less data retention on your side, no state duplication, less sync, less bugs. - - call and read ImGui::ShowTestWindow() for sample code demonstrating most features. - - see examples/ folder for standalone sample applications. e.g. examples/opengl_example/ - - customization: PushStyleColor()/PushStyleVar() or the style editor to tweak the look of the interface (e.g. if you want a more compact UI or a different color scheme). - - - getting started: - - initialisation: call ImGui::GetIO() to retrieve the ImGuiIO structure and fill the 'Settings' data. - - every frame: - 1/ in your mainloop or right after you got your keyboard/mouse info, call ImGui::GetIO() and fill the 'Input' data, then call ImGui::NewFrame(). - 2/ use any ImGui function you want between NewFrame() and Render() - 3/ ImGui::Render() to render all the accumulated command-lists. it will call your RenderDrawListFn handler that you set in the IO structure. - - all rendering information are stored into command-lists until ImGui::Render() is called. - - ImGui never touches or know about your GPU state. the only function that knows about GPU is the RenderDrawListFn handler that you must provide. - - effectively it means you can create widgets at any time in your code, regardless of "update" vs "render" considerations. - - refer to the examples applications in the examples/ folder for instruction on how to setup your code. - - a typical application skeleton may be: - - // Application init - ImGuiIO& io = ImGui::GetIO(); - io.DisplaySize.x = 1920.0f; - io.DisplaySize.y = 1280.0f; - io.DeltaTime = 1.0f/60.0f; - io.IniFilename = "imgui.ini"; - // TODO: Fill others settings of the io structure - - // Load texture - unsigned char* pixels; - int width, height, bytes_per_pixels; - io.Fonts->GetTexDataAsRGBA32(pixels, &width, &height, &bytes_per_pixels); - // TODO: copy texture to graphics memory. - // TODO: store your texture pointer/identifier in 'io.Fonts->TexID' - - // Application main loop - while (true) - { - // 1) get low-level input - // e.g. on Win32, GetKeyboardState(), or poll your events, etc. - - // 2) TODO: fill all fields of IO structure and call NewFrame - ImGuiIO& io = ImGui::GetIO(); - io.MousePos = mouse_pos; - io.MouseDown[0] = mouse_button_0; - io.KeysDown[i] = ... - ImGui::NewFrame(); - - // 3) most of your application code here - you can use any of ImGui::* functions at any point in the frame - ImGui::Begin("My window"); - ImGui::Text("Hello, world."); - ImGui::End(); - GameUpdate(); - GameRender(); - - // 4) render & swap video buffers - ImGui::Render(); - // swap video buffer, etc. - } - - - after calling ImGui::NewFrame() you can read back 'io.WantCaptureMouse' and 'io.WantCaptureKeyboard' to tell if ImGui - wants to use your inputs. if it does you can discard/hide the inputs from the rest of your application. - - API BREAKING CHANGES - ==================== - - Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix. - Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code. - - - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped().

Kept inline redirection function (will obsolete). - - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once. - - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now. - - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior - - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing() - - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused) - - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions. - - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader. - (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels. - this sequence: - const void* png_data; - unsigned int png_size; - ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); - // - became: - unsigned char* pixels; - int width, height; - io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); - // - io.Fonts->TexID = (your_texture_identifier); - you now have much more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. - it is now recommended your sample the font texture with bilinear interpolation. - (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID. - (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix) - (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets - - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver) - - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph) - - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility - - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered() - - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly) - - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity) - - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale() - - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn - - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically) - - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite - - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes - - - FREQUENTLY ASKED QUESTIONS (FAQ), TIPS - ====================================== - - Q: Can I have multiple widgets with the same label? - A: Yes. A primer on the use of labels/IDs in ImGui.. - - - Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget). - to do so they need an unique ID. unique ID are typically derived from a string label, an integer index or a pointer. - - Button("OK"); // Label = "OK", ID = hash of "OK" - Button("Cancel"); // Label = "Cancel", ID = hash of "Cancel" - - - Elements that are not clickable, such as Text() items don't need an ID. - - - ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" in two different windows - or in two different locations of a tree. - - - if you have a same ID twice in the same location, you'll have a conflict: - - Button("OK"); - Button("OK"); // ID collision! Both buttons will be treated as the same. - - Fear not! this is easy to solve and there are many ways to solve it! - - - when passing a label you can optionally specify extra unique ID information within string itself. This helps solving the simpler collision cases. - use "##" to pass a complement to the ID that won't be visible to the end-user: - - Button("Play##0"); // Label = "Play", ID = hash of "Play##0" - Button("Play##1"); // Label = "Play", ID = hash of "Play##1" (different from above) - - - occasionally (rarely) you might want change a label while preserving a constant ID. This allows you to animate labels. - use "###" to pass a label that isn't part of ID: - - Button("Hello###ID"; // Label = "Hello", ID = hash of "ID" - Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above) - - - use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window. - this is the most convenient way of distinguish ID if you are iterating and creating many UI elements. - you can push a pointer, a string or an integer value. remember that ID are formed from the addition of everything in the ID stack! - - for (int i = 0; i < 100; i++) - { - PushID(i); - Button("Click"); // Label = "Click", ID = hash of integer + "label" (unique) - PopID(); - } - - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj); - Button("Click"); // Label = "Click", ID = hash of pointer + "label" (unique) - PopID(); - } - - for (int i = 0; i < 100; i++) - { - MyObject* obj = Objects[i]; - PushID(obj->Name); - Button("Click"); // Label = "Click", ID = hash of string + "label" (unique) - PopID(); - } - - - more example showing that you can stack multiple prefixes into the ID stack: - - Button("Click"); // Label = "Click", ID = hash of "Click" - PushID("node"); - Button("Click"); // Label = "Click", ID = hash of "node" + "Click" - PushID(my_ptr); - Button("Click"); // Label = "Click", ID = hash of "node" + ptr + "Click" - PopID(); - PopID(); - - - tree nodes implicitly creates a scope for you by calling PushID(). - - Button("Click"); // Label = "Click", ID = hash of "Click" - if (TreeNode("node")) - { - Button("Click"); // Label = "Click", ID = hash of "node" + "Click" - TreePop(); - } - - - when working with trees, ID are used to preserve the opened/closed state of each tree node. - depending on your use cases you may want to use strings, indices or pointers as ID. - e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change. - e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense! - - Q: How do I update to a newer version of ImGui? - A: Overwrite the following files: - imgui.cpp - imgui.h - stb_rect_pack.h - stb_textedit.h - stb_truetype.h - Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. - - Q: Why is my text output blurry? - A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f) - - Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13) - A: Use the font atlas to load the TTF file you want: - - io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); - io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() - - Q: How can I load multiple fonts? - A: Use the font atlas to pack them into a single texture: - - ImFont* font0 = io.Fonts->AddFontDefault(); - ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); - ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels); - io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() - // the first loaded font gets used by default - // use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime - - Q: How can I render and input Chinese, Japanese, Korean characters? - A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. ImGui will support UTF-8 encoding across the board. - Character input depends on you passing the right character code to io.AddInputCharacter(). The example applications do that. - - io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters - io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() - io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application - - - tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code. - - tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug" - - tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window. - - tip: you can call Render() multiple times (e.g for VR renders). - - tip: call and read the ShowTestWindow() code for more example of how to use ImGui! - - - ISSUES & TODO-LIST - ================== - - - misc: merge or clarify ImVec4 vs ImRect? - - window: add horizontal scroll - - window: fix resize grip rendering scaling along with Rounding style setting - - window: autofit feedback loop when user relies on any dynamic layout (window width multiplier, column). maybe just clearly drop manual autofit? - - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. - - window: allow resizing of child windows (possibly given min/max for each axis?) - - window: background options for child windows, border option (disable rounding) - - window: resizing from any sides? + mouse cursor directives for app. - - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. - - widgets: clean up widgets internal toward exposing everything. - - main: considering adding EndFrame()/Init(). some constructs are awkward in the implementation because of the lack of them. - - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes - - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode? -!- input number: large int not reliably supported because of int<>float conversions. - - input number: optional range min/max for Input*() functions - - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled) - - input number: use mouse wheel to step up/down - - input number: non-decimal input. - - text: proper alignment options - - layout: horizontal layout helper (github issue #97) - - layout: more generic alignment state (left/right/centered) for single items? - - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding. - - columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (github issue #125) - - columns: declare column set (each column: fixed size, %, fill, distribute default size among fills) (github issue #125) - - columns: columns header to act as button (~sort op) and allow resize/reorder (github issue #125) - - columns: user specify columns size (github issue #125) - - popup: border options. richer api like BeginChild() perhaps? (github issue #197) - - combo: turn child handling code into pop up helper - - combo: contents should extends to fit label if combo widget is small - - listbox: multiple selection - - listbox: user may want to initial scroll to focus on the one selected value? - ! menubar, menus (github issue #126) - - tabs - - gauge: various forms of gauge/loading bars widgets - - color: better color editor. - - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots) - - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value) - - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID) - - file selection widget -> build the tool in our codebase to improve model-dialog idioms - - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt() - - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). - - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate. - - text edit: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now. - - text edit: centered text for slider as input text so it matches typical positioning. - - text edit: flag to disable live update of the user buffer. - - text edit: field resize behavior - field could stretch when being edited? hover tooltip shows more text? - - text edit: add multi-line text edit - - tree: add treenode/treepush int variants? because (void*) cast from int warns on some platforms/settings - - settings: write more decent code to allow saving/loading new fields - - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file - ! style: store rounded corners in texture to use 1 quad per corner (filled and wireframe). so rounding have minor cost. - - style: checkbox: padding for "active" color should be a multiplier of the - - style: colorbox not always square? - - text: simple markup language for color change? - - log: LogButtons() options for specifying depth and/or hiding depth slider - - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope) - - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard) - - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs. - - filters: set a current filter that tree node can automatically query to hide themselves - - filters: handle wildcards (with implicit leading/trailing *), regexps - - shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus) - ! keyboard: tooltip & combo boxes are messing up / not honoring keyboard tabbing - - keyboard: full keyboard navigation and focus. - - input: rework IO to be able to pass actual events to fix temporal aliasing issues. - - input: support track pad style scrolling & slider edit. - - tooltip: move to fit within screen (e.g. when mouse cursor is right of the screen). - - portability: big-endian test/support (github issue #81) - - misc: mark printf compiler attributes on relevant functions - - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL) - - misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon? - - style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? - - style editor: color child window height expressed in multiple of line height. - - optimization/render: use indexed rendering to reduce vertex data cost (e.g. for remote/networked imgui) - - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)? - - optimization: turn some the various stack vectors into statically-sized arrays - - optimization: better clipping for multi-component widgets -*/ - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif +// Source altered and distributed from https://github.com/AdrienHerubel/imgui +#include +#include +#define _USE_MATH_DEFINES +#include #include "imgui.h" -#include // toupper, isprint -#include // sqrtf, fabsf, fmodf, powf, cosf, sinf, floorf, ceilf -#include // intptr_t -#include // vsnprintf, sscanf -#include // new (ptr) #ifdef _MSC_VER -#pragma warning (disable: 4505) // unreferenced local function has been removed (stb stuff) -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen +# define snprintf _snprintf #endif -// Clang warnings with -Weverything -#ifdef __clang__ -#pragma clang diagnostic ignored "-Wold-style-cast" // warning : use of old-style cast // yes, they are more terse. -#pragma clang diagnostic ignored "-Wfloat-equal" // warning : comparing floating point with == or != is unsafe // storing and comparing against same constants ok. -#pragma clang diagnostic ignored "-Wformat-nonliteral" // warning : format string is not a string literal // passing non-literal to vsnformat(). yes, user passing incorrect format strings can crash the code. -#pragma clang diagnostic ignored "-Wexit-time-destructors" // warning : declaration requires an exit-time destructor // exit-time destruction order is undefined. if MemFree() leads to users code that has been disabled before exit it might cause problems.

You will then -// need to provide your own APIs in the same file which will access the -// static functions. -// -// The basic concept is that you provide a "string" object which -// behaves like an array of characters. stb_textedit uses indices to -// refer to positions in the string, implicitly representing positions -// in the displayed textedit. This is true for both plain text and -// rich text; even with rich text stb_truetype interacts with your -// code as if there was an array of all the displayed characters. -// -// Symbols that must be the same in header-file and implementation mode: -// -// STB_TEXTEDIT_CHARTYPE the character type -// STB_TEXTEDIT_POSITIONTYPE small type that a valid cursor position -// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow -// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer -// -// Symbols you must define for implementation mode: -// -// STB_TEXTEDIT_STRING the type of object representing a string being edited, -// typically this is a wrapper object with other data you need -// -// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) -// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters -// starting from character #n (see discussion below) -// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character -// to the xpos of the i+1'th char for a line of characters -// starting at character #n (i.e. accounts for kerning -// with previous char) -// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character -// (return type is int, -1 means not valid to insert) -// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based -// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize -// as manually wordwrapping for end-of-line positioning -// -// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i -// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) -// -// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key -// -// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left -// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right -// STB_TEXTEDIT_K_UP keyboard input to move cursor up -// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down -// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME -// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END -// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME -// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END -// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor -// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor -// STB_TEXTEDIT_K_UNDO keyboard input to perform undo -// STB_TEXTEDIT_K_REDO keyboard input to perform redo -// -// Optional: -// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode -// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), -// required for WORDLEFT/WORDRIGHT -// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT -// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT -// -// Todo: -// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page -// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page -// -// Keyboard input must be encoded as a single integer value; e.g. a character code -// and some bitflags that represent shift states. to simplify the interface, SHIFT must -// be a bitflag, so we can test the shifted state of cursor movements to allow selection, -// i.e. (STB_TEXTED_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. -// -// You can encode other things, such as CONTROL or ALT, in additional bits, and -// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, -// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN -// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, -// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the -// API below. The control keys will only match WM_KEYDOWN events because of the -// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN -// bit so it only decodes WM_CHAR events. -// -// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed -// row of characters assuming they start on the i'th character--the width and -// the height and the number of characters consumed.

For this -// reason, it provides an interface that is compatible with computing the -// layout incrementally--we try to make sure we make as few passes through -// as possible. (For example, to locate the mouse pointer in the text, we -// could define functions that return the X and Y positions of characters -// and binary search Y and then X, but if we're doing dynamic layout this -// will run the layout algorithm many times, so instead we manually search -// forward in one pass. Similar logic applies to e.g. up-arrow and -// down-arrow movement.) -// -// If it's run in a widget that *has* cached the layout, then this is less -// efficient, but it's not horrible on modern computers. But you wouldn't -// want to edit million-line files with it. - - -//////////////////////////////////////////////////////////////////////////// -//////////////////////////////////////////////////////////////////////////// -//// -//// Header-file mode -//// -//// - -#ifndef INCLUDE_STB_TEXTEDIT_H -#define INCLUDE_STB_TEXTEDIT_H - -//////////////////////////////////////////////////////////////////////// -// -// STB_TexteditState -// -// Definition of STB_TexteditState which you should store -// per-textfield;

It has to be updated each time you want to simulate a step forward in time. Most of the time, + you want to update the world right before rendering a new frame in a real-time application. \\ + + To update the physics world, you need to use the \texttt{DynamicsWorld::update()} method. This method will perform collision detection and update the + position and orientation of the bodies and joints. After updating the world, you will be able to get the new position and orientation of your bodies for the next + frame to render. This method requires a \emph{timeStep} parameter. This is the amount of time you want to advance the physics simulation (in seconds). \\ + + The smaller the time step you pick, the more precise the simulation will be but it can also be more expensive to compute. For a real-time application, you + probably want a time step of at most $\frac{1}{60}$ seconds to + have at least a 60 Hz framerate. Most of the time, physics engines prefer to work with a constant time step. It means that you should always call + the \texttt{DynamicsWorld::update()} method with the same time step parameter. You do not want to use the time between two frames as your time step because it will + not be constant. \\ + + You can use the following technique. First, you choose a constant time step for the physics. Let say the time step is $\frac{1}{60}$ seconds. Then, at each frame, + you compute the time difference between the current frame and the previous one and you accumulate this difference in a variable called \emph{accumulator}. The accumulator + is initialized to zero at the beginning of your application and is updated at each frame. The idea is to divide the time in the accumulator in several constant time steps. + For instance, if your accumulator contains $0.145$ seconds, it means that we can take $8$ physics steps of $\frac{1}{60}$ seconds during the current frame. Note that + $0.012$ seconds will remain in the accumulator and will probably be used in the next frame. As you can see, multiple physics steps can be taken at each frame. It is + important to understand that each call to the \texttt{DynamicsWorld::update()} method is done using a constant time step that is not varying with the framerate. \\ + + Here is what the code looks like at each frame: \\ \begin{lstlisting} -// Start the simulation -world.start(); + +// Constant physics time step +const float timeStep = 1.0 / 60.0; + +// Get the current system time +long double currentFrameTime = getCurrentSystemTime(); + +// Compute the time difference between the two frames +long double deltaTime = currentFrameTime - previousFrameTime; + +// Update the previous time +previousFrameTime = currentFrameTime; + +// Add the time difference in the accumulator +accumulator += mDeltaTime; + +// While there is enough accumulated time to take +// one or several physics steps +while (accumulator >= timeStep) { + + // Update the Dynamics world with a constant time step + dynamicsWorld->update(timeStep); + + // Decrease the accumulated time + accumulator -= timeStep; +} + \end{lstlisting} - - \vspace{0.6cm} - - Then, each time you have to compute the next frame to render in your application, you need to update the state of the world. To do that, you simply need to call this method: \\ - - \begin{lstlisting} -// Update the world by taking a simulation step -world.update(); - \end{lstlisting} - - \vspace{0.6cm} - - When the \texttt{DynamicsWorld::update()} method is called, collision detection is performed and the position and orientation of the bodies are updated accordingly. - After updating the world, you will be able to get the updated position and orientation of the bodies for the next frame. Make sure that you call - the \texttt{DynamicsWorld::start()} method before calling the \texttt{DynamicsWorld::update()} method. \\ - - You can also use the \texttt{DynamicsWorld::stop()} method to stop the simulation. You will then be able to start it again and continue updating it. \\ - - Note that you can get the elapsed time (in seconds) from the beginning of the physics simulation using the \texttt{DynamicsWorld::getPhysicsTime()} method. - This can be useful to - create some animations. + \subsection{Destroying the Dynamics World} From 1bde11f245806de07a12b1cf6c33cdb83046b882 Mon Sep 17 00:00:00 2001 From: Daniel Chappuis Date: Thu, 13 Aug 2015 19:47:29 +0200 Subject: [PATCH 36/36] Fix compilation errors on Visual Studio --- testbed/CMakeLists.txt | 2 +- testbed/common/Cone.cpp | 2 +- testbed/common/ConvexMesh.cpp | 2 +- testbed/common/Cylinder.cpp | 2 +- testbed/common/Dumbbell.cpp | 2 +- testbed/common/VisualContactPoint.cpp | 2 +- testbed/opengl-framework/src/maths/Matrix4.h | 3 ++- testbed/scenes/raycast/RaycastScene.cpp | 4 ++-- 8 files changed, 10 insertions(+), 9 deletions(-) diff --git a/testbed/CMakeLists.txt b/testbed/CMakeLists.txt index 4d3ecdac..cd66c695 100644 --- a/testbed/CMakeLists.txt +++ b/testbed/CMakeLists.txt @@ -28,7 +28,7 @@ SET(CMAKE_CXX_FLAGS "-std=c++0x") #ADD_DEFINITIONS(-DGL3) # Headers -INCLUDE_DIRECTORIES("src/" "opengl-framework/src/" "glfw/include/" "common/" "scenes/" "imgui/") +INCLUDE_DIRECTORIES(${GLEW_INCLUDE_PATH} "src/" "opengl-framework/src/" "glfw/include/" "common/" "scenes/" "imgui/") # Testbed source files SET(TESTBED_SOURCES diff --git a/testbed/common/Cone.cpp b/testbed/common/Cone.cpp index 6657ed9d..079a6189 100644 --- a/testbed/common/Cone.cpp +++ b/testbed/common/Cone.cpp @@ -236,7 +236,7 @@ void Cone::createVBOAndVAO() { // Create th VBO for the indices data mVBOIndices.create();

This method will + a \texttt{std::vector} with the list of all the current contact manifolds of the world. A contact manifold may contain several contact points. \\ + + The following example shows how to get all the contacts of the world using this method: \\ + + \begin{lstlisting} +std::vector manifolds; + +// Get all the contacts of the world +manifolds = dynamicsWorld->getContactsList(); +std::vector::iterator it; + +// For each contact manifold of the body +for (it = manifolds.begin(); it != manifolds.end(); ++it) { + ContactManifold* manifold = *it; + + // For each contact point of the manifold + for (int i=0; igetNbContactPoints(); i++) { + + // Get the contact point + ContactPoint* point = manifold->getContactPoint(i); + + // Get the world-space contact point on body 1 + Vector3 pos = point->getWorldPointOnBody1(); + + // Get the world-space contact normal + Vector3 normal = point->getNormal(); + } +} + \end{lstlisting} + + \vspace{0.6cm} + + Note that this technique to retrieve the contacts, if you use it between the \texttt{DynamicsWorld::update()} calls, will only give you the contacts are the end of + each frame. You will probably miss several contacts that have occured in the physics internal sub-steps.

Also note that a contact manifold contains some persistent contact points that + have may have been there for several frames. + + \section{Receiving Feedback} + \label{sec:receiving_feedback} Sometimes, you want to receive notifications from the physics engine when a given event happens. The \texttt{EventListener} class can be used for that purpose. In order to use it, you need to create a new class that inherits from the \texttt{EventListener} class and overrides some methods that will be called by the ReactPhysics3D library when some events occur. You also need to register your class in the physics world using the \texttt{DynamicsWorld::setEventListener()} as in the following code: \\ From 345afc1a1dc61e42b0a93dcf1e3696b1a84d6ec0 Mon Sep 17
