# GLFW ## Introduction GLFW is a free, Open Source, portable library for OpenGL and OpenGL ES application development. It provides a simple, platform-independent API for creating windows and contexts, reading input, handling events, etc. Version 3.0.4 is *not yet described*. As this is a patch release, there are no API changes. 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. ## 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. ## Changelog - Added the `GLFW_BUILD_DOCS` CMake option for controlling whether the documentation is built - Added the `_GLFW_USE_CONFIG_H` configuration macro for controlling whether to include the configuration header - Moved version number macro to `internal.h` for easier manual compilation - Renamed configuration header to `glfw_config.h` to avoid conflicts - Bugfix: The `glfw3.pc` file did not respect the `LIB_SUFFIX` CMake option - Bugfix: The `joysticks` test would segfault if a controller had no axes - [Win32] Allowed swap interval to be explicitly set to zero on DWM systems - [Win32] Bugfix: Removed joystick axis value negation left over from GLFW 2 - [Win32] Bugfix: Restoring windows using the Win+D hot key did not trigger the focus callback - [Win32] Bugfix: The disabled cursor mode clip rectangle was updated for unfocused windows - [Win32] Bugfix: Cursor was not properly re-centered over odd-sized windows - [Win32] Bugfix: Negative window positions were reported incorrectly - [Win32] Bugfix: The iconify callback was not triggered when switching away from a full screen window using Alt+Tab - [Cocoa] Added dependency on CoreVideo framework for refresh rate retrieval - [Cocoa] Enabled Lion full screen for resizable windowed mode windows - [Cocoa] Moved to Cocoa API for application transformation and activation - [Cocoa] Bugfix: The `GLFW_KEY_GRAVE_ACCENT` key was reported as `GLFW_KEY_WORLD_1` and vice versa - [Cocoa] Bugfix: The `GLFW_KEY_F13` key was reported as `GLFW_KEY_PRINT_SCREEN` - [Cocoa] Bugfix: Implicit conversion from `NSUInteger` to int caused warnings with Xcode 5 - [Cocoa] Bugfix: Use of undeclared selectors with `@selector` caused warnings with Xcode 5 - [Cocoa] Bugfix: The cursor remained visible if moved onto client area after having been set to hidden outside it - [Cocoa] Bugfix: The refresh rate was zero for all modes of certain monitors - [Cocoa] Bugfix: The `install_name` field of the dynamic library was not set - [Cocoa] Bugfix: Full screen windows were never reported as having focus - [Cocoa] Bugfix: A superfluous I/O flag test prevented video modes from being listed for Thunderbolt monitor - [Cocoa] Bugfix: Retrieving the name of some external displays caused segfault - [Cocoa] Bugfix: The 10.9 SDK defines `GLintptrARB` and `GLsizeiptrARB` differently from the Khronos `glext.h` - [Cocoa] Bugfix: Creating hidden windows would steal application focus - [Cocoa] Bugfix: Controllers were reported as having zero buttons and axes - [Cocoa] Bugfix: Removed joystick axis value negation left over from GLFW 2 - [X11] Added setting of the `WM_CLASS` property to the initial window title - [X11] Added support for `_NET_WM_BYPASS_COMPOSITOR` - [X11] Bugfix: Removed joystick axis value negation left over from GLFW 2 - [X11] Bugfix: The position of hidden windows was ignored by Metacity and Compiz ## Contact The official website for GLFW is [glfw.org](http://www.glfw.org/). There you can find the latest version of GLFW, as well as news, documentation and other information about the project. If you have questions related to the use of GLFW, we have a [support forum](https://sourceforge.net/p/glfw/discussion/247562/), and the IRC channel `#glfw` on [Freenode](http://freenode.net/). If you have a bug to report, a patch to submit or a feature you'd like to request, please file it in the [issue tracker](https://github.com/glfw/glfw/issues) on GitHub. Finally, if you're interested in helping out with the development of GLFW or porting it to your favorite platform, we have an occasionally active [developer's mailing list](https://lists.stacken.kth.se/mailman/listinfo/glfw-dev), or you could join us on `#glfw`. ## Acknowledgements GLFW exists because people around the world donated their time and lent their skills. - Bobyshev Alexander - artblanc - arturo - Matt Arsenault - Keith Bauer - John Bartholomew - Niklas Behrens - Niklas Bergström - Doug Binks - blanco - Lambert Clara - Andrew Corrigan - Noel Cower - Jarrod Davis - Olivier Delannoy - Paul R.
