回答1:
Basically, you can't. The main idea of the Wayland protocol is that a client doesn't know anything about the rest of the world.
You can, however, modify your compositor so that it will record the information you need about every windows in it and use those informations at will. Modifying a compositor, however, is a bit complex for a SO answer (and beyond my knowledge) so I guess you'll have to look around for good tutorials.
