Thanks for your answers. I did fool around with a popup, but it would
also overlap other windows, transient or not. Furthermore, I need it to
move relative to the window if that is moved.
Maybe it's best if I tell you what I'm trying to do in particular:
I'm working on something like a tooltip. However, I don't think I can
use normal tooltips, since I need to position it manually (actually, I
need it to move out of the way if the mouse cursor approaches it).
A popup sounds like the right way to do this, but I need to somehow wire
the popup's movement to the window's movement. Is there an easy way to
do that?
