not as easy as it sounds too :)

no. the wm - or any app can go raising windows above yours... you cant clock
windows in place to be on top as such. (ok we can argue of some nasty hacks and
methods if you are the wm... but thats a world on its own.)

ok. for a normal window yes its possible to get events to know if you got
obscured. they are called visibilitynotify events. BUT i am actually not sure if
they will be received by inputonly windows. but thats the path you want to go.
you could find if a window has been raised/lowered etc. by monitoring
creatnotifies on root, then on every windows created monitor structurenotifies
then look for configurenotify events and check the stacking sections (above,
window, event). again - i dont know how well gdk(gtk) supports this part of x so
you may have to dump into xlib.

hmm how is it meant to work? mouse goes to left or right side of window,
launcher buttons pop up and u click one to run something?
