## Introduction
GLFW is a free, Open Source, portable library for OpenGL and OpenGL ES
GLFW is a free, Open Source, multi-platform 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 3.0.2 adds support for OpenGL 4 on and precise scrolling deltas on OS
X and fixes for a number of bugs that together affect all supported platforms.
As this is a patch release, there are no API changes.
Version 3.1 is *not yet described*.
If you are new to GLFW, you may find the
[introductory tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW
@ -16,224 +14,135 @@ If you are new to GLFW, you may find the
[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
### Dependencies
To compile GLFW and the accompanying example programs, you will need **CMake**,
which will generate the project files or makefiles for your particular
development environment. If you are on a Unix-like system such as Linux or
FreeBSD or have a package system like Fink, MacPorts, Cygwin or Homebrew, you
can simply install its CMake package. If not, you can get installers for
Windows and OS X from the [CMake website](http://www.cmake.org/).
Additional dependencies are listed below.
#### Visual C++ on Windows
The Microsoft Platform SDK that is installed along with Visual C++ contains all
the necessary headers, link libraries and tools except for CMake.
#### MinGW or MinGW-w64 on Windows
These packages contain all the necessary headers, link libraries and tools
except for CMake.
#### MinGW or MinGW-w64 cross-compilation
Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages. For
example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
like Ubuntu have the `mingw-w64` package for both.
GLFW has CMake toolchain files in the `CMake/` directory that allow for easy
cross-compilation of Windows binaries. To use these files you need to add a
special parameter when generating the project files or makefiles:
cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
The exact toolchain file to use depends on the prefix used by the MinGW or
MinGW-w64 binaries on your system. You can usually see this in the /usr
directory. For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages
have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct
invocation would be:
cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .
For more details see the article
[CMake Cross Compiling](http://www.paraview.org/Wiki/CMake_Cross_Compiling) on
the CMake wiki.
#### Xcode on OS X
Xcode contains all necessary tools except for CMake. The necessary headers and
libraries are included in the core OS frameworks. Xcode can be downloaded from
the Mac App Store.
#### Unix-like systems with X11
To compile GLFW for X11, you need to have the X11 and OpenGL header packages
installed, as well as the basic development tools like GCC and make. For
example, on Ubuntu and other distributions based on Debian GNU/Linux, you need
to install the `xorg-dev` and `libglu1-mesa-dev` packages. The former pulls in
all X.org header packages and the latter pulls in the Mesa OpenGL and GLU
packages. Note that using header files and libraries from Mesa during
compilation *will not* tie your binaries to the Mesa implementation of OpenGL.
### Generating with CMake
Once you have all necessary dependencies, it is time to generate the project
files or makefiles for your development environment. CMake needs to know two
paths for this: the path to the source directory and the target path for the
generated files and compiled binaries. If these are the same, it is called an
in-tree build, otherwise it is called an out-of-tree build.
One of several advantages of out-of-tree builds is that you can generate files
and compile for different development environments using a single source tree.
#### Using CMake from the command-line
To make an in-tree build, enter the root directory of the GLFW source tree and
run CMake. The current directory is used as target path, while the path
provided as an argument is used to find the source tree.
cd <glfw-root-dir>
cmake .
To make an out-of-tree build, make another directory, enter it and run CMake
with the (relative or absolute) path to the root of the source tree as an
argument.
cd <glfw-root-dir>
mkdir build
cd build
cmake ..
#### Using the CMake GUI
If you are using the GUI version, choose the root of the GLFW source tree as
source location and the same directory or another, empty directory as the
destination for binaries. Choose *Configure*, change any options you wish to,
*Configure* again to let the changes take effect and then *Generate*.
### 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 CMake users 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.
#### Shared 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 `$PREFIX/lib`. If it is set to
`64`, it is installed to `$PREFIX/lib64`.
`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.
#### OS X specific 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_BUILD_UNIVERSAL` determines whether to build Universal Binaries.
#### Windows specific options
`USE_MSVC_RUNTIME_LIBRARY_DLL` determines whether to use the DLL version or the
static library version of the Visual C++ runtime library.
`GLFW_USE_DWM_SWAP_INTERVAL` determines whether the swap interval is set even
when DWM compositing is enabled. This can lead to severe jitter and is not
usually recommended.
`GLFW_USE_OPTIMUS_HPG` determines whether to export the `NvOptimusEnablement`
symbol, which forces the use of the high-performance GPU on nVidia Optimus
systems.
#### EGL specific 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.
`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.
## Installing GLFW
A rudimentary installation target is provided for all supported platforms via
CMake.
See the [Compiling GLFW](http://www.glfw.org/docs/latest/compile.html) guide in
the GLFW documentation.
## Using GLFW
See the [GLFW documentation](http://www.glfw.org/docs/latest/).
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.

* Adopters may modify this file to suit their platform. Adopters are
* encouraged to submit platform specific modifications to the Khronos
* group so that they can be included in future versions of this file.
* Please submit changes by sending them to the public Khronos Bugzilla
* (http://khronos.org/bugzilla) by filing a bug against product
* "Khronos (general)" component "Registry".
*
* A predefined template which fills in some of the bug fields can be
* reached using http://tinyurl.com/khrplatform-h-bugreport, but you
* must create a Bugzilla login first.
*
*
* See the Implementer's Guidelines for information about where this file
* should be located on your system and for more details of its use:
* http://www.khronos.org/registry/implementers_guide.pdf
*
* This file should be included as
* #include <KHR/khrplatform.h>
* by Khronos client API header files that use its types and defines.
*
* The types in khrplatform.h should only be used to define API-specific types.
*
* Types defined in khrplatform.h:
* khronos_int8_t signed 8 bit
* khronos_uint8_t unsigned 8 bit
* khronos_int16_t signed 16 bit
* khronos_uint16_t unsigned 16 bit
* khronos_int32_t signed 32 bit
* khronos_uint32_t unsigned 32 bit
* khronos_int64_t signed 64 bit
* khronos_uint64_t unsigned 64 bit
* khronos_intptr_t signed same number of bits as a pointer
* khronos_uintptr_t unsigned same number of bits as a pointer
* khronos_ssize_t signed size
* khronos_usize_t unsigned size
* khronos_float_t signed 32 bit floating point
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
* nanoseconds
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
* khronos_boolean_enum_t enumerated boolean type. This should
* only be used as a base type when a client API's boolean type is
* an enum. Client APIs which use an integer or other type for
* booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
*
* Calling convention macros defined in this file:
* KHRONOS_APICALL
* KHRONOS_APIENTRY
* KHRONOS_APIATTRIBUTES
*
* These may be used in function prototypes as:
*
* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(

@page build Building programs using GLFW

@tableofcontents
This is about compiling and linking programs that use GLFW. For information on
how to *write* such programs, start with the [introductory tutorial](@ref quick).
This is about compiling and linking applications that use GLFW. 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 files of your program where you use OpenGL or GLFW, you should include
the GLFW 3 header file, i.e.:
In the source files of your application where you use OpenGL or GLFW, you should
include the GLFW header file, i.e.:
@code
#include <GLFW/glfw3.h>
@endcode
This defines all the constants, types and function prototypes of the GLFW API.
It also includes the chosen client API header files (by default OpenGL), and
defines all the constants and types necessary for those headers to work on that
platform.
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.
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.
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 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.
`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
- 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
- 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
[GLEW](http://glew.sourceforge.net/), the GLEW header should also be included
*before* the GLFW one. The GLEW header defines macros that disable any OpenGL
header that the GLFW header includes and GLEW will work as expected.
[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
how that header behaves.
its behavior.
`GLFW_INCLUDE_GLCOREARB` makes the header include the modern `GL/glcorearb.h`
header (`OpenGL/gl3.h` on OS X) instead of the regular OpenGL header.
`GLFW_DLL` is required on Windows when using the GLFW DLL, to tell the compiler
that the GLFW functions are defined in a DLL.
`GLFW_INCLUDE_ES1` makes the header include the OpenGL ES 1.x `GLES/gl.h` header
instead of the regular OpenGL header.
The following macros control which OpenGL or OpenGL ES API header is included.
`GLFW_INCLUDE_ES2` makes the header include the OpenGL ES 2.0 `GLES2/gl2.h`
`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_ES3` makes the header include the OpenGL ES 3.0 `GLES3/gl3.h`
`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_NONE` makes the header not include any client API 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_GLU` makes the header include the GLU header *in addition to* the
OpenGL header. This should only be used with the default `GL/gl.h` header
(`OpenGL/gl.h` on OS X), i.e. if you are not using any of the above macros.
`GLFW_INCLUDE_ES31` makes the GLFW header include the OpenGL ES 3.1 `GLES3/gl31.h`
header instead of the regular OpenGL header.
`GLFW_DLL` is necessary when using the GLFW DLL on Windows, in order to explain
to the compiler that the GLFW functions will be coming from another executable.
It has no function on other platforms.
`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 a program under Windows that uses the static version of GLFW, you
must link with `opengl32`. If you are using GLU, you must also link with
`glu32`.
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 a program
that uses the DLL version of GLFW, you need to define the `GLFW_DLL` macro
*before* any inclusion of the GLFW header. This can be done either with
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. This can be done either with
a compiler switch or by defining it in your source code.
A program using the GLFW DLL does not need to link against any of its
dependencies, but you still have to link against `opengl32` if your program uses
OpenGL and `glu32` if it uses GLU.
An application using the GLFW DLL does not need to link against any of its
dependencies, but you still have to link against `opengl32` if your application
uses OpenGL and `glu32` if it uses GLU.
@subsection build_link_cmake_source With CMake and GLFW source
You can use the GLFW source tree directly from a project that uses CMake. This
way, GLFW will be built along with your application as needed.
With just a few changes to your `CMakeLists.txt` you can have the GLFW source
tree built along with your application.
Firstly, add the root directory of the GLFW source tree to your project. This
will add the `glfw` target and the necessary cache variables to your project.
add_subdirectory(path/to/glfw)
@code{.cmake}
add_subdirectory(path/to/glfw)
@endcode
To be able to include the GLFW header from your code, you need to tell the
compiler where to find it.
include_directories(path/to/glfw/include)
@code{.cmake}
include_directories(path/to/glfw/include)
@endcode
Once GLFW has been added to the project, the `GLFW_LIBRARIES` cache variable
contains all link-time dependencies of GLFW as it is currently configured. To
link against GLFW, link against them and the `glfw` target.
target_link_libraries(myapp glfw ${GLFW_LIBRARIES})
@code{.cmake}
target_link_libraries(myapp glfw ${GLFW_LIBRARIES})
@endcode
Note that `GLFW_LIBRARIES` does not include GLU, as GLFW does not use it. If
your application needs GLU, you can add it to the list of dependencies with the
`OPENGL_glu_LIBRARY` cache variable, which is implicitly created when the GLFW
CMake files look for OpenGL.
target_link_libraries(myapp glfw ${OPENGL_glu_LIBRARY} ${GLFW_LIBRARIES})
@code{.cmake}
target_link_libraries(myapp glfw ${OPENGL_glu_LIBRARY} ${GLFW_LIBRARIES})
@endcode

GLFW supports [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/),
and `glfw3.pc` file is generated when the GLFW library is built and installed
along with it.
and the `glfw3.pc` pkf-config file is generated when the GLFW library is built
and is installed along with it. A pkg-config file describes all necessary
compile-time and link-time flags and dependencies needed to use a library. When
they are updated or if they differ between systems, you will get the correct
ones automatically.
A typical compile and link command-line when using the static may look like this:

cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --static --libs glfw3`

@code{.sh}
cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --libs glfw3`
@endcode
You can also use the `glfw3.pc` file without installing it first, by using the
`PKG_CONFIG_PATH` environment variable.
env PKG_CONFIG_PATH=path/to/glfw/src cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --static --libs glfw3`

@endcode
The dependencies do not include GLU, as GLFW does not need it. On OS X, GLU is
built into the OpenGL framework, so if you need GLU you don't need to do
anything extra. If you need GLU and are using Linux or BSD, you should add
`-lGLU` to your link flags.

`glu` pkg-config module.
See the manpage and other documentation for pkg-config and your compiler and
linker for more information on how to link programs.

OpenGL, IOKit, CoreVideo and Carbon frameworks to the project as dependencies.
They can all be found in `/System/Library/Frameworks`.
@note GLFW needs the Carbon framework only to access the current keyboard layout
via the Text Input Source Services. This is one of the non-deprecated parts of
the Carbon API and the only way to access this information on OS X.
@subsection build_link_osx With command-line on OS X
If you do not wish to use pkg-config, you need to add the required frameworks
and libraries to your command-line using the `-l` and `-framework` switches,
i.e.:
It is recommended that you use [pkg-config](@ref build_link_pkgconfig) when
building from the command line on OS X. That way you will get any new
dependencies added automatically. If you still wish to build manually, you need
to add the required frameworks and libraries to your command-line yourself using
the `-l` and `-framework` switches.
cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit
If you are using the dynamic GLFW library, which is named `libglfw.3.dylib`, do:
Note that you do not add the `.framework` extension to a framework when adding
it from the command-line.
@code{.sh}

@endcode
If you are using the static library, named `libglfw3.a`, substitute `-lglfw3`
for `-lglfw`.
Note that you do not add the `.framework` extension to a framework when linking
against it from the command-line.
The OpenGL framework contains both the OpenGL and GLU APIs, so there is nothing
special to do when using GLU. Also note that even though your machine may have

@page compile Compiling GLFW
@tableofcontents
This is about compiling the GLFW library itself. For information on how to
build applications that use GLFW, see the @ref build guide.
@section compile_cmake Using CMake
GLFW uses [CMake](http://www.cmake.org/) to generate project files or makefiles
for a particular development environment. If you are on a Unix-like system such
as Linux or FreeBSD or have a package system like Fink, MacPorts, Cygwin or
Homebrew, you can simply install its CMake package. If not, you can download
installers for Windows and OS X from the [CMake website](http://www.cmake.org/).
@note CMake only generates project files or makefiles. It does not compile the
actual GLFW library. To compile GLFW, first generate these files and then use
them in your chosen development environment to compile the actual GLFW library.
@subsection compile_deps Dependencies
Once you have installed CMake, make sure that all other dependencies are
available. On some platforms, GLFW needs a few additional packages to be
installed. See the section for your chosen platform and development environment
below.
@subsubsection compile_deps_msvc Dependencies for Visual C++ on Windows
The Microsoft Platform SDK that is installed along with Visual C++ already
contains all the necessary headers, link libraries and tools except for CMake.
Move on to @ref compile_generate.
@subsubsection compile_deps_mingw Dependencies for MinGW or MinGW-w64 on Windows
Both the MinGW and the MinGW-w64 packages already contain all the necessary
headers, link libraries and tools except for CMake. Move on to @ref
compile_generate.
@subsubsection compile_deps_mingw_cross Dependencies for MinGW or MinGW-w64 cross-compilation
Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages. For
example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
like Ubuntu have the `mingw-w64` package for both.
GLFW has CMake toolchain files in the `CMake/` directory that allow for easy
cross-compilation of Windows binaries. To use these files you need to add a
special parameter when generating the project files or makefiles:
@code{.sh}
cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
@endcode
The exact toolchain file to use depends on the prefix used by the MinGW or
MinGW-w64 binaries on your system. You can usually see this in the /usr
directory. For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages
have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct
invocation would be:
@code{.sh}
cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .
@endcode
For more details see the article
[CMake Cross Compiling](http://www.paraview.org/Wiki/CMake_Cross_Compiling) on
the CMake wiki.
Once you have this set up, move on to @ref compile_generate.
@subsubsection compile_deps_xcode Dependencies for Xcode on OS X
Xcode comes with all necessary tools except for CMake. The required headers
and libraries are included in the core OS X frameworks. Xcode can be downloaded
from the Mac App Store or from the ADC Member Center.
Once you have Xcode installed, move on to @ref compile_generate.
@subsubsection compile_deps_x11 Dependencies for Linux and X11
To compile GLFW for X11, you need to have the X11 and OpenGL header packages
installed, as well as the basic development tools like GCC and make. For
example, on Ubuntu and other distributions based on Debian GNU/Linux, you need
to install the `xorg-dev` and `libglu1-mesa-dev` packages. The former pulls in
all X.org header packages and the latter pulls in the Mesa OpenGL and GLU
packages. GLFW itself doesn't need or use GLU, but some of the examples do.
Note that using header files and libraries from Mesa during compilation
_will not_ tie your binaries to the Mesa implementation of OpenGL.
Once you have installed the necessary packages, move on to @ref
compile_generate.
@subsection compile_generate Generating build files with CMake
Once you have all necessary dependencies it is time to generate the project
files or makefiles for your development environment. CMake needs to know two
paths for this: the path to the _root_ directory of the GLFW source tree (i.e.
_not_ the `src` subdirectory) and the target path for the generated files and
compiled binaries. If these are the same, it is called an in-tree build,
otherwise it is called an out-of-tree build.
One of several advantages of out-of-tree builds is that you can generate files
and compile for different development environments using a single source tree.
@note This section is about generating the project files or makefiles necessary
to compile the GLFW library, not about compiling the actual library.
@subsubsection compile_generate_cli Generating files with the CMake command-line tool
To make an in-tree build, enter the _root_ directory of the GLFW source tree
(i.e. _not_ the `src` subdirectory) and run CMake. The current directory is
used as target path, while the path provided as an argument is used to find the
source tree.
@code{.sh}
cd <glfw-root-dir>
cmake .
@endcode
To make an out-of-tree build, make another directory, enter it and run CMake
with the (relative or absolute) path to the root of the source tree as an
argument.
@code{.sh}
cd <glfw-root-dir>
mkdir build
cd build
cmake ..
@endcode
Once you have generated the project files or makefiles for your chosen
development environment, move on to @ref compile_compile.
@subsubsection compile_generate_gui Generating files with the CMake GUI
If you are using the GUI version, choose the root of the GLFW source tree as
source location and the same directory or another, empty directory as the
destination for binaries. Choose _Configure_, change any options you wish to,
_Configure_ again to let the changes take effect and then _Generate_.
Once you have generated the project files or makefiles for your chosen
development environment, move on to @ref compile_compile.
@subsection compile_compile Compiling the library
You should now have all required dependencies and the project files or makefiles
necessary to compile GLFW. 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.
@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)

- @ref window
- @ref monitor

@section context_object Context handles
@section context_object Context objects
The @ref GLFWwindow object encapsulates both a window and a context. They are
created with @ref glfwCreateWindow and destroyed with @ref glfwDestroyWindow (or
@ref glfwTerminate, if any remain). As the window and context are inseparably
linked, the object pointer is used as both a context and window handle.
A window object encapsulates both a top-level window and an OpenGL or OpenGL ES
context. It is created with @ref glfwCreateWindow and destroyed with @ref
glfwDestroyWindow or @ref glfwTerminate. See @ref window_creation for more
information.
As the window and context are inseparably linked, the window object also serves
as the context handle.
@section context_hints Context creation hints
@subsection context_hints Context creation hints
There are a number of hints, specified using @ref glfwWindowHint, related to
what kind of context is created. See
[context related hints](@ref window_hints_ctx) in the window handling guide.
[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 use the OpenGL or OpenGL ES APIs, you need to have a current
context of the proper type. The context encapsulates all render state and all
objects like textures and shaders.
Note that a context can only be current for a single thread at a time, and
a thread can only have a single context at a time.
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.

@subsection context_glext_auto Using an extension loader library
This is the easiest and best way to load extensions and newer versions of the
OpenGL or OpenGL ES API. One such library is
[glad](https://github.com/Dav1dde/glad) and there are several others. They will
take care of all the details of declaring and loading everything you need.
The following example will use glad, but other extension loader libraries work
similary.
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 --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.
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.
@code
#include <glad/glad.h>
#include <GLFW/glfw3.h>
@endcode
Finally you need to initialize glad once you have a matching 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 the context you created 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_context), 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
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.
to those functions. GLFW provides @ref glfwExtensionSupported and @ref
glfwGetProcAddress for manual loading of extensions and new API functions.
This can be done with GLFW, as will be described in this section, but usually
you will instead want to use a dedicated extension loading library such as
[GLEW](http://glew.sourceforge.net/). This kind of library greatly reduces the
amount of work necessary to use both OpenGL extensions and modern versions of
the OpenGL API. GLEW in particular has been extensively tested with and works
well with GLFW.
@note It is recommended that you use an existing extension loader library, as
described above, instead of loading manually.

Many extensions, though not all, require the use of new OpenGL functions.
These entry points are often not exposed by your link libraries, making
it necessary to fetch them at run time. With @ref glfwGetProcAddress you can
retrieve the address of extension and non-extension 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

@page input Input guide
@tableofcontents
This guide introduces the input related functions of GLFW. 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 input_event 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 window_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
glfwSetCharCallback(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 of mouse motion and button presses,
system cursor appearance and behavior, and two-dimensional scrolling. All of
these are supported by GLFW.
@subsection input_cursor_pos Cursor position
If you wish to be notified when the system 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
This function only returns cached cursor positions. It does not poll the
system for the current position. Whenever you poll state, you risk missing the
state change you are looking for.
@subsection input_cursor_mode Cursor modes
The `GLFW_CURSOR` input mode provides several cursor modes for special forms of
mouse motion input. By default, the `GLFW_CURSOR_NORMAL` cursor mode is used,
meaning the regular arrow cursor or a [custom cursor](@ref input_cursor) 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, both via the cursor position callback and via position
polling.
@note You should not implement your own version of this functionality using
other features of GLFW. It will not work as robustly as `GLFW_CURSOR_DISABLED`,
as those features are not intended for this purpose.
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 input_cursor Cursor objects
GLFW supports creating custom system cursor images, encapsulated as @ref
GLFWcursor objects. They are created with @ref glfwCreateCursor and destroyed
with @ref glfwDestroyCursor (or @ref glfwTerminate, if any remain).
@subsubsection input_cursor_creation Cursor creation
A 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 sequental rows, starting from the top-left corner.
@subsubsection input_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 input_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 input_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 input_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 input_scroll 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 input_joy 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 input_joy_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 input_joy_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 input_joy_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 input_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 input_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 input_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. You need
to make a deep copy of the array if you want to keep the paths.

@page intro Introduction to the API
@tableofcontents
This guide introduces the basic concepts of GLFW and describes initialization,
error handling and API guarantees and limitations. For a broad but shallow
tutorial, see @ref quick instead. There are also guides for the other areas of
GLFW.
- @ref window
- @ref context
- @ref monitor
- @ref input
@section intro_init Initialization and termination
Before most GLFW functions may be called, the library must be initialized.
This initialization checks what features are available on the machine,
enumerates monitors and joysticks, initializes the timer and performs any
required platform-specific initialization.
Only the following functions may be called before the library has been
successfully initialized, and only from the main thread.
- @ref glfwGetVersion
- @ref glfwGetVersionString
- @ref glfwSetErrorCallback
- @ref glfwInit
- @ref glfwTerminate
Calling any other function before that time will cause a @ref
GLFW_NOT_INITIALIZED error.
@subsection intro_init_init Initializing GLFW
The library is initialized with @ref glfwInit, which returns zero if an error
occurred.
@code
if (!glfwInit())
{
// Handle initialization failure
}
@endcode
If any part of initialization fails, all remaining bits are terminated as if
@ref glfwTerminate was called. The library only needs to be initialized once
and additional calls to an already initialized library will simply return
non-zero immediately.
Once the library has been successfully initialized, it should be terminated
before the application exits.
@subsection intro_init_terminate Terminating GLFW
Before your application exits, you should terminate the GLFW library if it has
been initialized. 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.
<img src="spaces.svg" width="90%" />
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 any bugs in GLFW, 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
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,
they are copied before the function returns.
Pointer lifetimes are guaranteed not to be shortened in future minor 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 glfwDestroyCursor
- @ref glfwPollEvents
- @ref glfwWaitEvents
@subsection thread_safety Thread safety
Most GLFW functions may only be called from the main thread. The reference
documentation for every GLFW function states whether it is limited to the main
thread.
There are some general rules that make it easier to remember which functions are
limited to the main thread. The following tasks may only be performed on the
main thread:
- 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
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.
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.
Undefined behavior, i.e. behavior that is not described in reference
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.
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
@note Do not parse the version string to find the GLFW library version. The
@ref glfwGetVersion function provides the version of the library binary in
numeric form.

If you have used GLFW 2.x in the past, there is a
[transition guide](@ref moving) that explains what has changed and how to update
existing code to use the new API.
There are guides for each of the various areas of the API.
- @ref intro – initialization, error handling and high-level design
- @ref window – creating and working with windows and framebuffers
- @ref context – working with OpenGL and OpenGL ES contexts
- @ref monitor – enumerating and working with monitors and video modes
- @ref input – receiving events, polling and processing input
The [FAQ](http://www.glfw.org/faq.html) answers many common questions about the
design, implementation and use of GLFW.
The [reference documentation](modules.html) provides more detailed information
about specific functions.
Once you have written a program, see the @ref compile and @ref build guides.
Finally, the @ref compat guide explains what APIs, standards and protocols GLFW
uses and what happens when they are not present on a given machine.
This documentation was generated with Doxygen. The sources for it are available
in both the [source distribution](http://www.glfw.org/download.html) and

To see how GLFW views your monitor setup and its available video modes, run the
`modes` test program.
@section monitor_objects Monitor objects
The @ref GLFWmonitor object represents a currently connected monitor.
A monitor object represents a currently connected monitor and is represented as
a pointer to the [opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type
@ref GLFWmonitor. Monitor objects cannot be created or destroyed by the
application and retain their addresses until the monitors they represent are
disconnected or until the library is [terminated](@ref intro_init_terminate).
Each monitor has a current video mode, a list of supported video modes,
a virtual position, a human-readable name, an estimated physical size and
a gamma ramp. One of the monitors is the primary monitor.
The virtual position of a monitor is in
[screen coordinates](@ref coordinate_systems) and, together with the current
video mode, describes the viewports that the connected monitors provide into the
virtual desktop that spans them.

@section monitor_modes Retrieving video modes
Although GLFW generally does a good job at selecting a suitable video
mode for you when you open a full screen window, it is sometimes useful to
know exactly which modes are available on a certain system. For example,
you may want to present the user with a list of video modes to select
from. To get a list of available video modes, you can use the function
@ref glfwGetVideoModes.
@subsection monitor_event Monitor configuration changes
If you wish to be notified when a monitor is connected or disconnected, set
a monitor callback.
@code
glfwSetMonitorCallback(monitor_callback);
@endcode
The callback function receives the handle for the monitor that has been
connected or disconnected and a monitor action.
@code
void monitor_callback(GLFWmonitor* monitor, int event)

The GLFW 3 header is named @ref glfw3.h and moved to the `GLFW` directory, to
avoid collisions with the headers of other major versions. Similarly, the GLFW

[TinyCThread](https://github.com/tinycthread/tinycthread) projects created by
the original author of GLFW. These libraries implement a usable subset of the
threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use
TinyCThread.
However, GLFW 3 has better support for *use from multiple threads* than GLFW
2 had. Contexts can be made current on and rendered with from secondary
threads, and the documentation explicitly states which functions may be used
from secondary threads and which may only be used from the main thread, i.e. the
thread that calls main.

@subsection moving_image Image and texture loading
@subsection moving_image Removal of image and texture loading
The image and texture loading functions have been removed. 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 the
OpenGL texturing facilities. This would either add a number of external
would need not only to support other formats, but also modern extensions to
OpenGL texturing. This would either add a number of external
dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions
of these libraries.
As there already are libraries doing this, it seems unnecessary both to
duplicate this work and to tie this duplicate to GLFW. Projects similar to
GLFW, such as freeglut, could also gain from such a library. Also, would be no
platform-specific part of such a library, as both OpenGL and stdio are available
wherever GLFW is.

@subsection moving_stdcall Removal of GLFWCALL macro
The `GLFWCALL` macro, which made callback functions use
[__stdcall](http://msdn.microsoft.com/en-us/library/zxk0tw93.aspx) on Windows,
has been removed. GLFW is written in C, not Pascal. Removing this macro means
there's one less thing for application programmers to remember, i.e. the
requirement to mark all callback functions with `GLFWCALL`. It also simplifies
the creation of DLLs and DLL link libraries, as there's no need to explicitly
disable `@n` entry point suffixes.

@subsection moving_window_handles Window handle parameters
Because GLFW 3 supports multiple windows, window handle parameters have been
added to all window-related GLFW functions and callbacks. The handle of
a newly created window is returned by @ref glfwCreateWindow (formerly
`glfwOpenWindow`). Window handles are pointers to the
[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWwindow.

@subsection moving_monitor Explicit monitor selection
GLFW 3 provides support for multiple monitors. To request a full screen mode window,
instead of passing `GLFW_FULLSCREEN` you specify which monitor you wish the
window to use. The @ref glfwGetPrimaryMonitor function returns the monitor that
GLFW 2 would have selected, but there are many other
[monitor functions](@ref monitor). Monitor handles are pointers to the
[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWmonitor.

@note The framebuffer bit depth parameters of `glfwOpenWindow` have been turned
into [window hints](@ref window_hints), but as they have been given
[sane defaults](@ref window_hints_values) you rarely need to set these hints.
@subsection moving_autopoll Removal of automatic event polling
GLFW 3 does not automatically poll for events on @ref glfwSwapBuffers, which
means you need to call @ref glfwPollEvents or @ref glfwWaitEvents yourself.
Unlike buffer swap, which acts on a single window, __glfwPollEvents__ and
__glfwWaitEvents__ process events for all windows at once.

@subsection moving_context Explicit context management
Each GLFW 3 window has its own OpenGL context and only you, the application
programmer, can know which context should be current on which thread at any
given time. Therefore, GLFW 3 leaves that decision to you.
This means that you need to call @ref glfwMakeContextCurrent after creating
a window before you can call any OpenGL functions.
@subsection moving_hidpi Separation of window and framebuffer sizes
Window positions and sizes now use screen coordinates, which may not be the same
as pixels on machines with high-DPI monitors. This is important as OpenGL uses
pixels, not screen coordinates. For example, the rectangle specified with
`glViewport` needs to use pixels. Therefore, framebuffer size functions have
been added. You can retrieve the size of the framebuffer of a window with @ref
glfwGetFramebufferSize function. A framebuffer size callback has also been
added, which can be set with @ref glfwSetFramebufferSizeCallback.

@subsection moving_window_close Window closing changes
The `GLFW_OPENED` window parameter has been removed. As long as the window has
not been destroyed, whether through @ref glfwDestroyWindow or @ref
glfwTerminate, the window is "open".
A user attempting to close a window is now just an event like any other. Unlike
GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless
you choose them to be. 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. Instead, it is called after the
close flag has been set so it can override its value, if it chooses to, before
event processing completes. You may however not call @ref glfwDestroyWindow
from the close callback (or any other window related callback).
@par Old syntax
@code
int GLFWCALL window_close_callback(void);
@endcode
@par New syntax
@code
void window_close_callback(GLFWwindow* window);
@endcode
@note GLFW never clears the close flag to `GL_FALSE`, meaning you can use it
for other reasons to close the window as well, for example the user choosing
Quit from an in-game menu.
@subsection moving_hints Persistent window hints
The `glfwOpenWindowHint` function has been renamed to @ref glfwWindowHint.
Window hints are no longer reset to their default values on window creation, but
instead retain their values until modified by @ref glfwWindowHint or @ref
glfwDefaultWindowHints, or until the library is terminated and re-initialized.
@subsection moving_video_modes Video mode enumeration
Video mode enumeration is now per-monitor. 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. The `glfwGetDesktopMode` function, which
had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which
returns the current mode of a monitor.

@subsection moving_wheel Mouse wheel position
@subsection moving_cursorpos Cursor position changes
The `glfwGetMouseWheel` function has been removed. Scroll events do not
represent an absolute state, but is instead an interpretation of a relative
change in state, like character input. So, like character input, there is no
sane 'current state' to return. The mouse wheel callback has been replaced by
a [scroll callback](@ref GLFWscrollfun) that receives two-dimensional scroll
offsets.
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_stdcall GLFWCALL macro
@subsection moving_wheel Wheel position replaced by scroll offsets

@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_autopoll Automatic polling of events
GLFW 3 does not automatically poll for events on @ref glfwSwapBuffers, which
means you need to call @ref glfwPollEvents or @ref glfwWaitEvents yourself.
Unlike buffer swap, the event processing functions act on all windows at once.
@subsection moving_terminate Automatic termination
GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization. To
properly release all resources allocated by GLFW, you should therefore call @ref
glfwTerminate yourself before exiting.
GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization,
because `exit` calls registered functions from the calling thread and while it
is permitted to call `exit` from any thread, @ref glfwTerminate may only be
called from the main thread.
To release all resources allocated by GLFW, you should call @ref glfwTerminate
yourself, from the main thread, before the program terminates. Note that this
destroys all windows not already destroyed with @ref glfwDestroyWindow,
invalidating any window handles you may still have.
@subsection moving_glu GLU header inclusion
GLFW 3 does not include the GLU header by default and GLU itself has been
deprecated, but you can request that the GLFW 3 header includes it by defining
`GLFW_INCLUDE_GLU` before the inclusion of the GLFW 3 header.

@subsection moving_window_handles Window handles
Because GLFW 3 supports multiple windows, window handle parameters have been
added to all window-related GLFW functions and callbacks. The handle of
a newly created window is returned by @ref glfwCreateWindow (formerly
`glfwOpenWindow`). Window handles are of the `GLFWwindow*` type, i.e. a pointer
to an opaque struct.
@section moving_tables Name change tables
@subsection moving_monitor Multi-monitor support
GLFW 3 provides support for multiple monitors, adding the `GLFWmonitor*` handle
type and a set of related functions. To request a full screen mode window,
instead of passing `GLFW_FULLSCREEN` you specify which monitor you wish the
window to use. There is @ref glfwGetPrimaryMonitor that provides behaviour
similar to that of GLFW 2.
@subsection moving_window_close Window closing
Window closing is now just an event like any other. GLFW 3 windows won't
disappear from underfoot even when no close callback is set; instead the
window's close flag is set. You can query this flag using @ref
glfwWindowShouldClose, or capture close events by setting a close callback. The
close flag can be modified from any point in your program using @ref
glfwSetWindowShouldClose.
@subsection moving_context Explicit context management
Each GLFW 3 window has its own OpenGL context and only you, the user, can know
which context should be current on which thread at any given time. Therefore,
GLFW 3 makes no assumptions about when you want a certain context to be current,
leaving that decision to you.
This means, among other things, that you need to call @ref
glfwMakeContextCurrent after creating a window before you can call any OpenGL
functions.
@subsection moving_repeat Key repeat
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`.

To create smooth animation, a time source is needed. GLFW provides a timer that

@section quick_swap_buffers Swapping buffers
@subsection quick_swap_buffers Swapping buffers
GLFW windows always use double-buffering. 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.
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, it is time to swap the back and the
front buffers in order to display the rendered frame, and begin rendering a new
frame. This is done with @ref glfwSwapBuffers.
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.
@section quick_process_events Processing events
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.

GLFW needs to communicate regularly with the window system both in order to
receive events and to show that it hasn't locked up. Event processing must be
done regularly and is normally done each frame before rendering but after buffer
swap.

processing must be done regularly while you have visible windows and is normally

There are two ways to process pending events. @ref glfwPollEvents processes
only those events that have already been received and then returns immediately.
This is the best choice when rendering continually, like most games do.

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 just like @ref glfwPollEvents does. 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: A small GLFW application
@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 runs a loop clearing
the screen, rendering a triangle and processing events until the user closes the
window. It can be found in the source distribution as `examples/simple.c`, and
is by default compiled along with all other examples when you build GLFW.
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. There are
guides for each of the areas covered by GLFW. Each guide will introduce all the
functions for that category.
- @ref intro
- @ref window
- @ref context
- @ref monitor
- @ref input
@section quick_build Compiling and linking the program
The complete program above can be found in the source distribution as
`examples/simple.c` and is compiled along with all other examples when you
build GLFW. 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. Once you have written a program that uses GLFW, you
will need to compile and link it. How to do that depends on the development
environment you are using and is best explained by the documentation for that
environment. To learn about the details that are specific to GLFW, see
@ref build.

management and OpenGL and OpenGL ES context creation. GLFW supports multiple
windows, which can be either a normal desktop window or a full screen window.
This guide introduces the window related functions of GLFW. There are also
guides for the other areas of GLFW.

@section window_creation Window creation

The window and its context are created with @ref glfwCreateWindow, which
returns a handle to the created window object. For example, this creates a 640
by 480 windowed mode window:
A window and its OpenGL or OpenGL ES context are created with @ref
glfwCreateWindow, which returns a handle to the created window object. For
example, this creates a 640 by 480 windowed mode window:
@code
GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
@endcode
If window creation fails, `NULL` will be returned, so you need to check whether
it did.
If window creation fails, `NULL` will be returned, so it is necessary to check
the return value.
This handle is then passed to all window related functions, and is provided to
you along with input events, so you know which window received the input.
The window handle is passed to all window related functions and is provided to

To create a full screen window, you need to specify which monitor the window
should use. In most cases, the user's primary monitor is a good choice. For
more information about monitors, see the @ref monitor.
should use. In most cases, the user's primary monitor is a good choice.
For more information about retrieving monitors, see @ref monitor_monitors.
@code
GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", glfwGetPrimaryMonitor(), NULL);
@endcode
Full screen windows cover the entire display area of a monitor, have no border
or decorations, and change the monitor's resolution to the one most closely
matching the requested window size.
or decorations.
For more control over how the window and its context are created, see @ref
window_hints below.
Each field of the @ref GLFWvidmode structure corresponds to a function parameter
or window hint and combine to form the _desired video mode_ for that window.
The supported video mode most closely matching the desired video mode will be
set for the chosen monitor as long as the window is focused. For more
information about retrieving video modes, see @ref monitor_modes.
Video mode field | Corresponds to
----------------------- | ------------------------
GLFWvidmode.width | `width` parameter
GLFWvidmode.height | `height` parameter
GLFWvidmode.redBits | `GLFW_RED_BITS` hint
GLFWvidmode.greenBits | `GLFW_GREEN_BITS` hint
GLFWvidmode.blueBits | `GLFW_BLUE_BITS` hint
GLFWvidmode.refreshRate | `GLFW_REFRESH_RATE` hint
Once you have a full screen window, you can change its resolution with @ref
glfwSetWindowSize. The new video mode will be selected and set the same way as
the video mode chosen by @ref glfwCreateWindow.
@section window_destruction Window destruction
@subsubsection window_windowed_full_screen "Windowed full screen" windows
When you are done with the window, destroy it with the @ref glfwDestroyWindow
function.
By default, the original video mode of the monitor will be restored and the
window iconified if it loses input focus, to allow the user to switch back to
the desktop. This behavior can be disabled with the `GLFW_AUTO_ICONIFY` window
hint, for example if you wish to simultaneously cover multiple windows with full
screen windows.
To create a so called _windowed full screen_ or _borderless full screen_ window,
i.e. a full screen window that doesn't change the video mode of the monitor, you
need to request the current video mode of the chosen monitor.
@code
const GLFWvidmode* mode = glfwGetVideoMode(monitor);
glfwWindowHint(GLFW_RED_BITS, mode->redBits);
glfwWindowHint(GLFW_GREEN_BITS, mode->greenBits);
glfwWindowHint(GLFW_BLUE_BITS, mode->blueBits);
glfwWindowHint(GLFW_REFRESH_RATE, mode->refreshRate);
GLFWwindow* window = glfwCreateWindow(mode->width, mode->height, "My Title", monitor, NULL);
@endcode
GLFW will detect this and will not perform any mode setting for that window.
@subsection window_destruction Window destruction
When a window is no longer needed, destroy it with @ref glfwDestroyWindow.
@code
glfwDestroyWindow(window);
@endcode
Once this function is called, no more events will be delivered for that window
and its handle becomes invalid.
Window destruction always succeeds. Before the actual destruction, all
callbacks are removed so no further events will be delivered for the window.
All windows remaining when @ref glfwTerminate is called are destroyed as well.
When a full screen window is destroyed, the original video mode of its monitor
is restored, but the gamma ramp is left untouched.

@subsubsection window_hints_wnd Window related hints
@subsection window_hints_wnd Window related hints
`GLFW_RESIZABLE` specifies whether the (windowed mode) window will be resizable
_by the user_. The window will still be resizable using the @ref
glfwSetWindowSize function. This hint is ignored for full screen windows.
The `GLFW_RESIZABLE` hint specifies whether the window will be resizable *by the
user*. The window will still be resizable using the @ref glfwSetWindowSize
function. This hint is ignored for full screen windows.
The `GLFW_VISIBLE` hint specifies whether the window will be initially
`GLFW_VISIBLE` specifies whether the (windowed mode) window will be initially
visible. This hint is ignored for full screen windows.
The `GLFW_DECORATED` hint specifies whether the window will have window
`GLFW_DECORATED` specifies whether the (windowed mode) window will have window
decorations such as a border, a close widget, etc. This hint is ignored for
full screen windows. Note that even though a window may lack a close widget, it
is usually still possible for the user to generate close events.
`GLFW_FOCUSED` specifies whether the (windowed mode) window will be given input
focus when created. This hint is ignored for full screen and initially hidden
windows.
@subsection window_hints_fb Framebuffer related hints
The `GLFW_RED_BITS`, `GLFW_GREEN_BITS`, `GLFW_BLUE_BITS`, `GLFW_ALPHA_BITS`,
`GLFW_DEPTH_BITS` and `GLFW_STENCIL_BITS` hints specify the desired bit
depths of the various components of the default framebuffer.
The `GLFW_ACCUM_RED_BITS`, `GLFW_ACCUM_GREEN_BITS`, `GLFW_ACCUM_BLUE_BITS`
and `GLFW_ACCUM_ALPHA_BITS` hints specify the desired bit depths of the
various components of the accumulation buffer.
The `GLFW_AUX_BUFFERS` hint specifies the desired number of auxiliary
buffers.
The `GLFW_STEREO` hint specifies whether to use stereoscopic rendering.
The `GLFW_SAMPLES` hint specifies the desired number of samples to use for
multisampling. Zero disables multisampling.
The `GLFW_SRGB_CAPABLE` hint specifies whether the framebuffer should be
sRGB capable.
The `GLFW_REFRESH_RATE` hint specifies the desired refresh rate for full screen
windows. If set to zero, the highest available refresh rate will be used. This
`GLFW_AUTO_ICONIFY` specifies whether the (full screen) window will
automatically iconify and restore the previous video mode on focus loss. This
hint is ignored for windowed mode windows.
`GLFW_FLOATING` specifies whether the window will be floating above other
regular windows, also called topmost or always-on-top. This is intended
primarily for debugging purposes and cannot be used to implement proper full
screen windows. This hint is ignored for full screen windows.
@subsection window_hints_ctx Context related hints
The `GLFW_CLIENT_API` hint specifies which client API to create the context
for. Possible values are `GLFW_OPENGL_API` and `GLFW_OPENGL_ES_API`.
@subsubsection window_hints_fb Framebuffer related hints
The `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` hints
specify the client API version that the created context must be compatible
with.
`GLFW_RED_BITS`, `GLFW_GREEN_BITS`, `GLFW_BLUE_BITS`, `GLFW_ALPHA_BITS`,
`GLFW_DEPTH_BITS` and `GLFW_STENCIL_BITS` specify the desired bit depths of the
various components of the default framebuffer. `GLFW_DONT_CARE` means the
application has no preference.
For OpenGL, these hints are *not* hard constraints, as they don't have to
match exactly, but @ref glfwCreateWindow will still fail if the resulting
OpenGL version is less than the one requested. It is therefore perfectly
safe to use the default of version 1.0 for legacy code and you may still
get backwards-compatible contexts of version 3.0 and above when available.
`GLFW_ACCUM_RED_BITS`, `GLFW_ACCUM_GREEN_BITS`, `GLFW_ACCUM_BLUE_BITS` and
`GLFW_ACCUM_ALPHA_BITS` specify the desired bit depths of the various components
of the accumulation buffer. `GLFW_DONT_CARE` means the application has no
preference.
@par
Accumulation buffers are a legacy OpenGL feature and should not be used in new
code.
`GLFW_AUX_BUFFERS` specifies the desired number of auxiliary buffers.
`GLFW_DONT_CARE` means the application has no preference.

Auxiliary buffers are a legacy OpenGL feature and should not be used in new
code.
`GLFW_STEREO` specifies whether to use stereoscopic rendering. This is a hard
constraint.
`GLFW_SAMPLES` specifies the desired number of samples to use for multisampling.
Zero disables multisampling. `GLFW_DONT_CARE` means the application has no
preference.
`GLFW_SRGB_CAPABLE` specifies whether the framebuffer should be sRGB capable.
`GLFW_DOUBLEBUFFER` specifies whether the framebuffer should be double buffered.
You nearly always want to use double buffering. This is a hard constraint.
@subsubsection window_hints_mtr Monitor related hints
`GLFW_REFRESH_RATE` specifies the desired refresh rate for full screen windows.
If set to `GLFW_DONT_CARE`, the highest available refresh rate will be used.
This hint is ignored for windowed mode windows.
@subsubsection window_hints_ctx Context related hints
`GLFW_CLIENT_API` specifies which client API to create the context for.
Possible values are `GLFW_OPENGL_API` and `GLFW_OPENGL_ES_API`. This is a hard
constraint.
`GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` specify the client
API version that the created context must be compatible with. The exact
behavior of these hints depend on the requested client API.
@par OpenGL
`GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` are not hard
constraints, but creation will fail if the OpenGL version of the created context
is less than the one requested. It is therefore perfectly safe to use the
default of version 1.0 for legacy code and you may still get
backwards-compatible contexts of version 3.0 and above when available.

While there is no way to ask the driver for a context of the highest supported
version, most drivers provide this when you ask GLFW for a version
1.0 context.
version, GLFW will attempt to provide this when you ask for a version 1.0
context, which is the default for these hints.
For OpenGL ES, these hints are hard constraints.
@par OpenGL ES
`GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` are not hard
constraints, but creation will fail if the OpenGL ES version of the created
context is less than the one requested. Additionally, OpenGL ES 1.x cannot be
returned if 2.0 or later was requested, and vice versa. This is because OpenGL
ES 3.x is backward compatible with 2.0, but OpenGL ES 2.0 is not backard
compatible with 1.x.
If an OpenGL context is requested, the `GLFW_OPENGL_FORWARD_COMPAT` hint
specifies whether the OpenGL context should be forward-compatible, i.e. one
where all functionality deprecated in the requested version of OpenGL is
removed. This may only be used if the requested OpenGL version is 3.0 or
above. If another client API is requested, this hint is ignored.
`GLFW_OPENGL_FORWARD_COMPAT` specifies whether the OpenGL context should be
forward-compatible, i.e. one where all functionality deprecated in the requested
version of OpenGL is removed. This may only be used if the requested OpenGL
version is 3.0 or above. If OpenGL S is requested, this hint is ignored.
If an OpenGL context is requested, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
specifies whether to create a debug OpenGL context, which may have
additional error and performance issue reporting functionality. If another
client API is requested, this hint is ignored.
@par
Forward-compatibility is described in detail in the
[OpenGL Reference Manual](https://www.opengl.org/registry/).
If an OpenGL context is requested, the `GLFW_OPENGL_PROFILE` hint specifies
which OpenGL profile to create the context for. Possible values are one of
`GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE`, or
`GLFW_OPENGL_ANY_PROFILE` to not request a specific profile. If requesting
an OpenGL version below 3.2, `GLFW_OPENGL_ANY_PROFILE` must be used. If
another client API is requested, this hint is ignored.
`GLFW_OPENGL_DEBUG_CONTEXT` specifies whether to create a debug OpenGL context,
which may have additional error and performance issue reporting functionality.
If OpenGL ES is requested, this hint is ignored.
The `GLFW_CONTEXT_ROBUSTNESS` hint specifies the robustness strategy to be
used by the context. This can be one of `GLFW_NO_RESET_NOTIFICATION` or
`GLFW_OPENGL_PROFILE` specifies which OpenGL profile to create the context for.
Possible values are one of `GLFW_OPENGL_CORE_PROFILE` or
`GLFW_OPENGL_COMPAT_PROFILE`, or `GLFW_OPENGL_ANY_PROFILE` to not request
a specific profile. If requesting an OpenGL version below 3.2,
`GLFW_OPENGL_ANY_PROFILE` must be used. If another OpenGL ES is requested,
this hint is ignored.
@par
OpenGL profiles are described in detail in the
[OpenGL Reference Manual](https://www.opengl.org/registry/).
`GLFW_CONTEXT_ROBUSTNESS` specifies the robustness strategy to be used by the
context. This can be one of `GLFW_NO_RESET_NOTIFICATION` or
`GLFW_LOSE_CONTEXT_ON_RESET`, or `GLFW_NO_ROBUSTNESS` to not request
a robustness strategy.
`GLFW_CONTEXT_RELEASE_BEHAVIOR` specifies the release behavior to be
used by the context. Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`,
`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`. If the
behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context
creation API will be used. If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`,
the pipeline will be flushed whenever the context is released from being the
current one. If the behavior is `GLFW_RELEASE_BEHAVIOR_NONE`, the pipeline will
not be flushed on release.

* Original Amiga authors were R.J. Mical and Dale Luck.
* GLFW conversion by Marcus Geelnard
* Notes: - 360' = 2*PI [radian]
*
* - Distances between objects are created by doing a relative
* Z translations.
*
* - Although OpenGL enticingly supports alpha-blending,
* the shadow of the original Boing didn't affect the color

* - [Marcus] Changed timing scheme from interval driven to frame-
* time based animation steps (which results in much smoother
* movement)
*
* History of Amiga Boing:
*
* Boing was demonstrated on the prototype Amiga (codenamed "Lorraine") in
* 1985. According to legend, it was written ad-hoc in one night by
* R. J. Mical and Dale Luck. Because the bouncing ball animation was so fast
* and smooth, attendees did not believe the Amiga prototype was really doing
* the rendering. Suspecting a trick, they began looking around the booth for
* a hidden computer or VCR.
