class
#include <Magnum/Platform/GlxApplication.h>
GlxApplication GLX application.
Application using pure X11 and GLX. Supports keyboard and mouse handling. Available on desktop OpenGL and OpenGL ES using GLX on Linux.
Bootstrap application
The usage is very similar to Sdl2Application, for which fully contained base application along with CMake setup is available, see its documentation for more information.
General usage
This application library depends on the X11 library and is built if MAGNUM_WITH_GLXAPPLICATION
is enabled when building Magnum. To use this library with CMake, request the GlxApplication
component of the Magnum
package and link to the Magnum::GlxApplication
target:
find_package(Magnum REQUIRED GlxApplication) # ... target_link_libraries(your-app PRIVATE Magnum::GlxApplication)
Additionally, if you're using Magnum as a CMake subproject, do the following before calling find_package()
to ensure it's enabled, as the library is not built by default:
set(MAGNUM_WITH_GLXAPPLICATION ON CACHE BOOL "" FORCE) add_subdirectory(magnum EXCLUDE_FROM_ALL)
If no other application is requested, you can also use the generic Magnum::Application
alias to simplify porting. See Downloading and building and Usage with CMake for more information.
In C++ code you need to implement at least drawEvent() to be able to draw on the screen. The subclass can be then used directly in main()
— see convenience macro MAGNUM_
class MyApplication: public Platform::GlxApplication { // implement required methods... }; MAGNUM_GLXAPPLICATION_MAIN(MyApplication)
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.

Function documentation
Magnum:: Platform:: GlxApplication:: GlxApplication(const Arguments& arguments,
const Configuration& configuration = Configuration{},
const GLConfiguration& glConfiguration = GLConfiguration{}) explicit
Construct with an OpenGL context.
Parameters | |
---|---|
arguments | Application arguments |
configuration | Application configuration |
glConfiguration | OpenGL context configuration |
Creates application with default or user-specified configuration. See Configuration and GLConfiguration for more information. The program exits if the context cannot be created, see tryCreate() for an alternative.
Magnum:: Platform:: GlxApplication:: GlxApplication(const Arguments& arguments,
NoCreateT) explicit
Construct without creating a window.
Parameters | |
---|---|
arguments | Application arguments |
Unlike above, the window is not created and must be created later with create() or tryCreate().
