/** @nosubgrouping
@brief GLFW application
Application using GLFW toolkit. Supports keyboard and mouse handling with
support for changing cursor and mouse tracking and warping.
This application library is available only on desktop OpenGL (Linux, Windows,
OS X). It depends on **GLFW** library and is built if `WITH_GLFWAPPLICATION` is
enabled in CMake.
## Bootstrap application
Fully contained base application using @ref GlfwApplication along with
CMake setup is available in `base-glfw` branch of
[Magnum Bootstrap](https://github.com/mosra/magnum-bootstrap) repository,
download it as [tar.gz](https://github.com/mosra/magnum-bootstrap/archive/base-glfw.tar.gz)
or [zip](https://github.com/mosra/magnum-bootstrap/archive/base-glfw.zip) file.
After extracting the downloaded archive you can build and run the application
with these four commands:
mkdir build && cd build
cmake ..
cmake --build .
./src/MyApplication # or ./src/Debug/MyApplication
See @ref cmake for more information.
## General usage
In CMake you need to request `GlfwApplication` component of `Magnum` package
and link to `Magnum::GlfwApplication` target. If no other application is
requested, you can also use generic `Magnum::Application` alias to simplify
porting. Again, see @ref building and @ref cmake for more information.
In C++ code you need to implement at least @ref drawEvent() to be able to draw
on the screen. The subclass can be then used directly in `main()` -- see
convenience macro @ref MAGNUM_GLFWAPPLICATION_MAIN(). See @ref platform for
more information.
@code
class MyApplication: public Platform::GlfwApplication {
// implement required methods...
};
MAGNUM_GLFWAPPLICATION_MAIN(MyApplication)
@endcode
If no other application header is included, this class is also aliased to
`Platform::Application` and the macro is aliased to `MAGNUM_APPLICATION_MAIN()`
to simplify porting.
