/** @nosubgrouping
@brief GLUT application
@deprecated This application is based on an outdated toolkit and scheduled for
removal in a future release. Please consider switching to either
@ref Sdl2Application or @ref GlfwApplication as soon as possible.
Application using the [GLUT](http://freeglut.sourceforge.net/) 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,
macOS). It depends on the [GLUT](http://freeglut.sourceforge.net/) library and
is built if `WITH_GLUTAPPLICATION` is enabled when building Magnum.
@section Platform-GlutApplication-usage General usage
In order to use this library from CMake, you need to request the
`GlutApplication` component of the `Magnum` package and link to the
`Magnum::GlutApplication` target:
@code{.cmake}
find_package(Magnum REQUIRED GlutApplication)
# ...
target_link_libraries(your-app Magnum::GlutApplication)
@endcode
If no other application is requested, you can also use the 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 @cpp main() @ce
--- see convenience macro @ref MAGNUM_GLUTAPPLICATION_MAIN(). See @ref platform
for more information.
@code{.cpp}
class MyApplication: public Platform::GlutApplication {
// implement required methods...
};
MAGNUM_GLUTAPPLICATION_MAIN(MyApplication)
@endcode
If no other application header is included, this class is also aliased to
@cpp Platform::Application @ce and the macro is aliased to
@cpp MAGNUM_APPLICATION_MAIN() @ce to simplify porting.
