<description summary="Protocol for requesting fractional surface scales">
This protocol allows a compositor to suggest for surfaces to render at
fractional scales.
A client can submit scaled content by utilizing wp_viewport. This is done by
creating a wp_viewport object for the surface and setting the destination
rectangle to the surface size before the scale factor is applied.
The buffer size is calculated by multiplying the surface size by the
intended scale.
The wl_surface buffer scale should remain set to 1.
If a surface has a surface-local size of 100 px by 50 px and wishes to
submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
be used and the wp_viewport destination rectangle should be 100 px by 50 px.
For toplevel surfaces, the size is rounded halfway away from zero. The
rounding algorithm for subsurface position and size is not defined.

<description summary="Protocol for requesting activation of surfaces">
The way for a client to pass focus to another toplevel is as follows.
The client that intends to activate another toplevel uses the
xdg_activation_v1.get_activation_token request to get an activation token.
This token is then forwarded to the client, which is supposed to activate
one of its surfaces, through a separate band of communication.
One established way of doing this is through the XDG_ACTIVATION_TOKEN
environment variable of a newly launched child process. The child process
should unset the environment variable again right after reading it out in
order to avoid propagating it to other child processes.
Another established way exists for Applications implementing the D-Bus
interface org.freedesktop.Application, which should get their token under
activation-token on their platform_data.
In general activation tokens may be transferred across clients through
means not described in this protocol.
The client to be activated will then pass the token
it received to the xdg_activation_v1.activate request. The compositor can
then use this token to decide how to react to the activation request.
The token the activating client gets may be ineffective either already at
the time it receives it, for example if it was not focused, for focus
stealing prevention. The activating client will have no way to discover
the validity of the token, and may still forward it to the to be activated
client.
The created activation token may optionally get information attached to it
that can be used by the compositor to identify the application that we
intend to activate. This can for example be used to display a visual hint
about what application is being started.
Warning! The protocol described in this file is currently in the testing
phase. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes can
only be done by creating a new major version of the extension.

@subsection build_link_win32 With MinGW or Visual C++ on Windows
### With Visual C++ and GLFW binaries {#build_link_win32}
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.
If you are using a downloaded [binary
archive](https://www.glfw.org/download.html), first make sure you have the
archive matching the architecture you are building for (32-bit or 64-bit), or
you will get link errors. Also make sure you are using the binaries for your
version of Visual C++ or you may get other link errors.
When using MinGW to link an application with the static version of GLFW, you
must also explicitly link with `gdi32`. Other toolchains including MinGW-w64
include it in the set of default libraries along with other dependencies like
`user32` and `kernel32`.
There are two version of the static GLFW library in the binary archive, because
it needs to use the same base run-time library variant as the rest of your
executable.
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 @ref
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.
One is named `glfw3.lib` and is for projects with the _Runtime Library_ project
option set to _Multi-threaded DLL_ or _Multi-threaded Debug DLL_. The other is
named `glfw3_mt.lib` and is for projects with _Runtime Library_ set to
_Multi-threaded_ or _Multi-threaded Debug_. To use the static GLFW library you
will need to add `path/to/glfw3.lib` or `path/to/glfw3_mt.lib` to the
_Additional Dependencies_ project option.
If you compiled a GLFW static library yourself then there will only be one,
named `glfw3.lib`, and you have to make sure the run-time library variant
matches.
The DLL version of the GLFW library is named `glfw3.dll`, but you will be
linking against the `glfw3dll.lib` link library. To use the DLL you will need
to add `path/to/glfw3dll.lib` to the _Additional Dependencies_ project option.
All of its dependencies are already listed there by default, but when building
with the DLL version of GLFW, you also need to define the @ref GLFW_DLL. This
can be done either in the _Preprocessor Definitions_ project option or by
defining it in your source code before including the GLFW header.
```c
#define GLFW_DLL
#include <GLFW/glfw3.h>
```
All link-time dependencies for GLFW are already listed in the _Additional
Dependencies_ option by default.
@subsection build_link_cmake_source With CMake and GLFW source
### With MinGW-w64 and GLFW binaries {#build_link_mingw}
This is intended for building a program from the command-line or by writing
a makefile, on Windows with [MinGW-w64][] and GLFW binaries. These can be from
a downloaded and extracted [binary archive](https://www.glfw.org/download.html)
or by compiling GLFW yourself. The paths below assume a binary archive is used.
If you are using a downloaded binary archive, first make sure you have the
archive matching the architecture you are building for (32-bit or 64-bit) or you
will get link errors.
Note that the order of source files and libraries matter for GCC. Dependencies
must be listed after the files that depend on them. Any source files that
depend on GLFW must be listed before the GLFW library. GLFW in turn depends on

If you are using the static version of the GLFW library, which is named
`libglfw3.a`, do:
```sh
gcc -o myprog myprog.c -I path/to/glfw/include path/to/glfw/lib-mingw-w64/libglfw3.a -lgdi32
```
If you are using the DLL version of the GLFW library, which is named
`glfw3.dll`, you will need to use the `libglfw3dll.a` link library.
```sh
gcc -o myprog myprog.c -I path/to/glfw/include path/to/glfw/lib-mingw-w64/libglfw3dll.a -lgdi32
```
The resulting executable will need to find `glfw3.dll` to run, typically by
keeping both files in the same directory.
When you are building with the DLL version of GLFW, you will also need to define
the @ref GLFW_DLL macro. This can be done in your source files, as long as it
done before including the GLFW header:
```c
#define GLFW_DLL
#include <GLFW/glfw3.h>
```
It can also be done on the command-line:
```sh
gcc -o myprog myprog.c -D GLFW_DLL -I path/to/glfw/include path/to/glfw/lib-mingw-w64/libglfw3dll.a -lgdi32

they are updated or if they differ between systems, you will get the correct
ones automatically.
This is intended for building a program from the command-line or by writing

@subsection compile_deps Installing dependencies
### Installing dependencies {#compile_deps}
The C/C++ development environments in Visual Studio, Xcode and MinGW come with
all necessary dependencies for compiling GLFW, but on Unix-like systems like
Linux and FreeBSD you will need a few extra packages.
@subsubsection compile_deps_x11 Dependencies for X11
#### Dependencies for Wayland and X11 {#compile_deps_wayland}
To compile GLFW for X11, you need to have the X11 development packages
installed. They are not needed to build or run programs that use GLFW.
On Debian and derivatives like Ubuntu and Linux Mint the `xorg-dev` meta-package
pulls in the development packages for all of X11.
@code{.sh}
sudo apt install xorg-dev

On Fedora and derivatives like Red Hat the X11 extension packages
`libXcursor-devel`, `libXi-devel`, `libXinerama-devel` and `libXrandr-devel`
required by GLFW pull in all its other dependencies.
@code{.sh}
sudo dnf install libXcursor-devel libXi-devel libXinerama-devel libXrandr-devel
@endcode
On FreeBSD the X11 headers are installed along the end-user X11 packages, so if
you have an X server running you should have the headers as well. If not,
install the `xorgproto` package.
@code{.sh}

On Cygwin the `libXcursor-devel`, `libXi-devel`, `libXinerama-devel`,
`libXrandr-devel` and `libXrender-devel` packages in the Libs section of the GUI
installer will install all the headers and other development related files GLFW
requires for X11.

### Runtime platform selection {#platform}

a single library binary support both X11 and Wayland on Linux and other Unix-like systems.
a single library binary support both Wayland and X11 on Linux and other Unix-like systems.
You can control platform selection via the @ref GLFW_PLATFORM initialization hint. By
default, this is set to @ref GLFW_ANY_PLATFORM, which will look for supported window
systems in order of priority and select the first one it finds. It can also be set to any
specific platform to have GLFW only look for that one.
@code
```c
glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_X11);
@endcode
```
This mechanism also provides the Null platform, which is always supported but needs to be
explicitly requested. This platform is effectively a stub, emulating a window system on
a single 1080p monitor, but will not interact with any actual window system.
@code
```c
glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_NULL);
@endcode
```
You can test whether a library binary was compiled with support for a specific platform
with @ref glfwPlatformSupported.
@code
```c
if (glfwPlatformSupported(GLFW_PLATFORM_WAYLAND))
glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_WAYLAND);
@endcode
```
Once GLFW has been initialized, you can query which platform was selected with @ref
glfwGetPlatform.
@code
```c

### Physical size {#monitor_size}
The physical size of a monitor in millimetres, or an estimation of it, can be
retrieved with @ref glfwGetMonitorPhysicalSize. This has no relation to its

glfwGetMonitorContentScale.
@code
```c
float xscale, yscale;
glfwGetMonitorContentScale(monitor, &xscale, &yscale);

```
The content scale is the ratio between the current DPI and the platform's
default DPI. This is especially important for text and any UI elements. If the
pixel dimensions of your UI scaled by this look appropriate on your machine then
it should appear at a reasonable size on other machines regardless of their DPI
and scaling settings. This relies on the system DPI and scaling settings being
somewhat correct.
The content scale may depend on both the monitor resolution and pixel density
and on user settings. It may be very different from the raw DPI calculated from
the physical size and current resolution.
For more information on what the content scale is and how to use it, see
[window content scale](@ref window_scale).

### Window handle parameters {#moving_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 pointers to the
[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWwindow.

### Explicit monitor selection {#moving_monitor}
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

@section news_34 Release notes for version 3.4
@subsection features_34 New features in version 3.4
@subsubsection context_user_34 Multiple window contexts
GLFW now provides the ability to create multiple OpenGL and OpenGL ES
contexts for a given window. Called user contexts, a [GLFWusercontext](@ref context_user)
can be created using @ref glfwCreateUserContext,
destroyed using @ref glfwDestroyUserContext, and managed with
@ref glfwMakeUserContextCurrent and @ref glfwGetCurrentUserContext.
For more information see the [user context](@ref context_user) documentation.
@subsubsection runtime_platform_34 Runtime platform selection
GLFW now supports being compiled for multiple backends and selecting between
them at runtime with the @ref GLFW_PLATFORM init hint. After initialization the
selected platform can be queried with @ref glfwGetPlatform. You can check if
support for a given platform is compiled in with @ref glfwPlatformSupported.
@subsubsection standard_cursors_34 More standard cursors
GLFW now provides the standard cursor shapes @ref GLFW_RESIZE_NWSE_CURSOR and
@ref GLFW_RESIZE_NESW_CURSOR for diagonal resizing, @ref GLFW_RESIZE_ALL_CURSOR
for omnidirectional resizing and @ref GLFW_NOT_ALLOWED_CURSOR for showing an
action is not allowed.
Unlike the original set, these shapes may not be available everywhere and
creation will then fail with the new @ref GLFW_CURSOR_UNAVAILABLE error.
The cursors for horizontal and vertical resizing are now referred to as @ref
GLFW_RESIZE_EW_CURSOR and @ref GLFW_RESIZE_NS_CURSOR, and the pointing hand
cursor is now referred to as @ref GLFW_POINTING_HAND_CURSOR. The older names
are still available.
For more information see @ref cursor_standard.
@subsubsection mouse_passthrough_34 Mouse event passthrough
GLFW now provides the [GLFW_MOUSE_PASSTHROUGH](@ref GLFW_MOUSE_PASSTHROUGH_hint)
window hint for making a window transparent to mouse input, lettings events pass
to whatever window is behind it. This can also be changed after window
creation with the matching [window attribute](@ref GLFW_MOUSE_PASSTHROUGH_attrib).
@subsubsection wayland_libdecor_34 Wayland libdecor decorations
GLFW now supports improved fallback window decorations via
[libdecor](https://gitlab.freedesktop.org/libdecor/libdecor).
Support for libdecor can be toggled before GLFW is initialized with the
[GLFW_WAYLAND_LIBDECOR](@ref GLFW_WAYLAND_LIBDECOR_hint) init hint. It is
enabled by default.
@subsubsection wayland_app_id_34 Wayland app_id specification
GLFW now supports specifying the app_id for a Wayland window using the
[GLFW_WAYLAND_APP_ID](@ref GLFW_WAYLAND_APP_ID_hint) window hint string.
@subsubsection features_34_angle_backend Support for ANGLE rendering backend selection
GLFW now provides the
[GLFW_ANGLE_PLATFORM_TYPE](@ref GLFW_ANGLE_PLATFORM_TYPE_hint) init hint for
requesting a specific rendering backend when using
[ANGLE](https://chromium.googlesource.com/angle/angle/) to create OpenGL ES
contexts.
@subsubsection captured_cursor_34 Captured cursor mode
GLFW now supports confining the cursor to the window content area with the @ref
GLFW_CURSOR_CAPTURED cursor mode.
For more information see @ref cursor_mode.
@subsubsection features_34_init_allocator Support for custom memory allocator
GLFW now supports plugging a custom memory allocator at initialization with @ref
glfwInitAllocator. The allocator is a struct of type @ref GLFWallocator with
function pointers corresponding to the standard library functions `malloc`,
`realloc` and `free`.
For more information see @ref init_allocator.
@subsubsection features_34_position_hint Window hints for initial position
GLFW now provides the @ref GLFW_POSITION_X and @ref GLFW_POSITION_Y window hints for
specifying the initial position of the window. This removes the need to create a hidden
window, move it and then show it. The default value of these hints is
`GLFW_ANY_POSITION`, which selects the previous behavior.
@subsubsection features_34_win32_keymenu Support for keyboard access to Windows window menu
GLFW now provides the
[GLFW_WIN32_KEYBOARD_MENU](@ref GLFW_WIN32_KEYBOARD_MENU_hint) window hint for
enabling keyboard access to the window menu via the Alt+Space and
Alt-and-then-Space shortcuts. This may be useful for more GUI-oriented
applications.
@subsection caveats Caveats for version 3.4
@subsubsection native_34 Multiple sets of native access functions
Because GLFW now supports runtime selection of platform (window system), a library binary
may export native access functions for multiple platforms. Starting with version 3.4 you
must not assume that GLFW is running on a platform just because it exports native access
functions for it. After initialization, you can query the selected platform with @ref
glfwGetPlatform.
@subsubsection version_string_34 Version string format has been changed
Because GLFW now supports runtime selection of platform (window system), the version
string returned by @ref glfwGetVersionString has been expanded. It now contains the names
of all APIs for all the platforms that the library binary supports.
@subsubsection joysticks_34 Joystick support is initialized on demand
The joystick part of GLFW is now initialized when first used, primarily to work
around faulty Windows drivers that cause DirectInput to take up to several
seconds to enumerate devices.
This change will usually not be observable. However, if your application waits
for events without having first called any joystick function or created any
visible windows, the wait may never unblock as GLFW may not yet have subscribed
to joystick related OS events.
To work around this, call any joystick function before waiting for events, for
example by setting a [joystick callback](@ref joystick_event).
@subsubsection wayland_alpha_34 Frambuffer may lack alpha channel on older Wayland systems
On Wayland, when creating an EGL context on a machine lacking the new
`EGL_EXT_present_opaque` extension, the @ref GLFW_ALPHA_BITS window hint will be
ignored and the framebuffer will have no alpha channel. This is because some
Wayland compositors treat any buffer with an alpha channel as per-pixel
transparent.
If you want a per-pixel transparent window, see the
[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint) window
hint.
@subsubsection standalone_34 Tests and examples are disabled when built as a subproject
GLFW now does not build the tests and examples when it is added as
a subdirectory of another CMake project. To enable these, set the @ref
GLFW_BUILD_TESTS and @ref GLFW_BUILD_EXAMPLES cache variables before adding the
GLFW subdirectory.
@code{.cmake}
set(GLFW_BUILD_EXAMPLES ON CACHE BOOL "" FORCE)
set(GLFW_BUILD_TESTS ON CACHE BOOL "" FORCE)
add_subdirectory(path/to/glfw)
@endcode
@subsubsection initmenu_34 macOS main menu now created at initialization
GLFW now creates the main menu and completes the initialization of NSApplication
during initialization. Programs that do not want a main menu can disable it
with the [GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint) init hint.
@subsubsection corevideo_34 CoreVideo dependency has been removed
GLFW no longer depends on the CoreVideo framework on macOS and it no longer
needs to be specified during compilation or linking.
@subsubsection caveat_fbtransparency_34 Framebuffer transparency requires DWM transparency
GLFW no longer supports framebuffer transparency enabled via @ref
GLFW_TRANSPARENT_FRAMEBUFFER on Windows 7 if DWM transparency is off
(the Transparency setting under Personalization > Window Color).
@subsubsection emptyevents_34 Empty events on X11 no longer round-trip to server
Events posted with @ref glfwPostEmptyEvent now use a separate unnamed pipe
instead of sending an X11 client event to the helper window.
@subsection deprecations_34 Deprecations in version 3.4
@subsection removals_34 Removals in 3.4
@subsubsection vulkan_static_34 GLFW_VULKAN_STATIC CMake option has been removed
This option was used to compile GLFW directly linked with the Vulkan loader, instead of
using dynamic loading to get hold of `vkGetInstanceProcAddr` at initialization. This is
now done by calling the @ref glfwInitVulkanLoader function before initialization.
If you need backward compatibility, this macro can still be defined for GLFW 3.4 and will
have no effect. The call to @ref glfwInitVulkanLoader can be conditionally enabled in
your code by checking the @ref GLFW_VERSION_MAJOR and @ref GLFW_VERSION_MINOR macros.
@subsubsection osmesa_option_34 GLFW_USE_OSMESA CMake option has been removed
This option was used to compile GLFW for the Null platform. The Null platform is now
always supported. To produce a library binary that only supports this platform, the way
this CMake option used to do, you will instead need to disable the default platform for
the target OS. This means setting the @ref GLFW_BUILD_WIN32, @ref GLFW_BUILD_COCOA or
@ref GLFW_BUILD_X11 CMake option to false.
You can set all of them to false and the ones that don't apply for the target OS will be
ignored.
@subsubsection wl_shell_34 Support for the wl_shell protocol has been removed
Support for the wl_shell protocol has been removed and GLFW now only supports
the XDG-Shell protocol. If your Wayland compositor does not support XDG-Shell
then GLFW will fail to initialize.

### Initializing and terminating GLFW {#quick_init_term}
Before you can use most GLFW functions, the library must be initialized. On
successful initialization, `GLFW_TRUE` is returned. If an error occurred,
`GLFW_FALSE` is returned.
@code
```c
if (!glfwInit())
{
// Initialization failed
}
@endcode
```
Note that `GLFW_TRUE` and `GLFW_FALSE` are and will always be one and zero.
When you are done using GLFW, typically just before the application exits, you
need to terminate GLFW.
@code
```c
glfwTerminate();
@endcode
```
This destroys any remaining windows and releases any other resources allocated by
GLFW. After this call, you must initialize GLFW again before using any GLFW
functions that require it.

a GLFW window being moved, or an error occurring. Callbacks are C functions (or

@code
```c
void error_callback(int error, const char* description)
{
fprintf(stderr, "Error: %s\n", description);
}
@endcode
```
Callback functions must be set, so GLFW knows to call them. The function to set
the error callback is one of the few GLFW functions that may be called before
initialization, which lets you be notified of errors both during and after
initialization.
@code
```c
glfwSetErrorCallback(error_callback);

@subsection quick_create_window Creating a window and context
### Creating a window and context {#quick_create_window}
The window and its OpenGL context are created with a single call to @ref
glfwCreateWindow, which returns a handle to the created combined window and
context object

```c
GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);

and its handle becomes invalid.
@subsection quick_context_current Making the OpenGL context current
### Making the OpenGL context current {#quick_context_current}
Before you can use the OpenGL API, you must have a current OpenGL context.

### Receiving input events {#quick_key_input}
Each window has a large number of callbacks that can be set to receive all the
various kinds of events. To receive key press and release events, create a key
callback function.
@code
```c
static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
{
if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
glfwSetWindowShouldClose(window, GLFW_TRUE);
}

The key callback, like other window related callbacks, are set per-window.
@code
```c

In order for event callbacks to be called when events occur, you need to process
events as described below.
@subsection quick_render Rendering with OpenGL

Once you have a current OpenGL context, you can use OpenGL normally. In this
tutorial, a multicolored rotating triangle will be rendered. The framebuffer
size needs to be retrieved for `glViewport`.
