Using GTK with Wayland

The GDK Wayland backend provides support for running GTK applications under a Wayland compositor. To run your application in this way, select the Wayland backend by setting GDK_BACKEND=wayland.

On UNIX, the Wayland backend is enabled by default, so you don’t need to do anything special when compiling it, and everything should just work.
