This removes the (undocumented) behavior where glfwShowWindow would bring the window to front and set input focus. That function now does what it says.

## Introduction
|
|
|
|
GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and
|
|
Vulkan application development. It provides a simple, platform-independent API
|
|
for creating windows, contexts and surfaces, reading input, handling events, etc.
|
|
|
|
Version 3.2 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
|
|
3 useful. If you have used GLFW 2 in the past, there is a
|
|
[transition guide](http://www.glfw.org/docs/latest/moving.html) for moving to
|
|
the GLFW 3 API.
|
|
|
|
|
|
## Compiling GLFW
|
|
|
|
See the [Compiling GLFW](http://www.glfw.org/docs/latest/compile.html) guide in
|
|
the GLFW documentation.
|
|
|
|
|
|
## Using GLFW
|
|
|
|
See the
|
|
[Building programs that use GLFW](http://www.glfw.org/docs/latest/build.html)
|
|
guide in the GLFW documentation.
|
|
|
|
|
|
## Reporting bugs
|
|
|
|
Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
|
|
Please always include the name and version of the OS where the bug occurs and
|
|
the version of GLFW used. If you have cloned it, include the commit ID used.
|
|
|
|
If it's a build issue, please also include the build log and the name and
|
|
version of your development environment.
|
|
|
|
If it's a context creation issue, please also include the make and model of your
|
|
graphics card and the version of your driver.
|
|
|
|
This will help both us and other people experiencing the same bug.
|
|
|
|
|
|
## Dependencies
|
|
|
|
GLFW itself needs only the headers and libraries for your window system. It
|
|
does not need the headers for any context creation API (WGL, GLX, EGL, NSGL) or
|
|
rendering API (OpenGL, OpenGL ES, Vulkan) to enable support for them.
|
|
|
|
The examples and test programs depend on a number of tiny libraries. These are
|
|
located in the `deps/` directory.
|
|
|
|
- [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
|
|
with command-line options
|
|
- [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
|
|
examples
|
|
- An OpenGL 3.2 core loader generated by
|
|
[glad](https://github.com/Dav1dde/glad) for examples using modern OpenGL
|
|
- [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
|
|
examples
|
|
- [Vulkan headers](https://www.khronos.org/registry/vulkan/) for Vulkan tests
|
|
|
|
The Vulkan example additionally requires the Vulkan SDK to be installed, or it
|
|
will not be included in the build.
|
|
|
|
The documentation is generated with [Doxygen](http://doxygen.org/). If CMake
|
|
does not find Doxygen, the documentation will not be generated.
