Innitial (currently nont working) code lives at: https://github.com/Zubnix/wayland-javafx
I do have a few questions: - How are you supposed to handle events coming from the display system itself? For example, I don't see any X events being handled. How/where should that be done? - How does the client rendering loop works? Like in X, in wayland you have to "flush" queued op requests to the compositor. How/where should that be done?
