the raise will raise ontop of everything - BUt something may raise itself above
your window immediately afterwards too...

inputonly windows are invisible windows. you can map,unmap, move, resize, get
events (mouswe moves, button presses, key events etc.) on them, but they do not
visually do anything on the screen.

yes. every time a window is created (or destroyed etc. etc.) if you select for
the right event mask (structure & substructurenotify) x will tell u when the
root window and children of it change (created, destoryed, reparent, move,
resize, restack etc.) with events. this is close to what a window manager does
(close, but not quite). i'd definitely suggets the inputonly window. u will
never be ab;e to sensibly pass events on, but in the area of the screen the
inputonly window lives, you can "eat" all the events yourself :)

hmm - in which case here is what i'd recommend. you use an inputonly window -
stick in a corner, edge etc. where u want the "activate" area of the screen
(that activates the toolbar), then pop up the toolbar (so its raised on TOP of
your input only window - have this as an exception in general to maintaining the
on-top stacking of your inputonly window) then if the mouse exits that toolbor,
hide it again. monitor stacking as mentioned above with structure &
substructurenotify mask set on root and handle the events. the problemn here is
really gdk/gtk. i dont know how well it will deal with this. if u did it in xlib
u'd be fine, but i am not sure if gdk/gtk will be 100% happy. others might know
if ti will or will not.
