I actually don't think 'sticky' is the right term here .... what Rogier
is asking for, is a small toolbox window, which stays on top of the
application's edit window(s).

This code should demo what I think is being asked for. Move one of the top
level windows onto another virtual desktop. Whenever you click the 'Show'
button, the 'toolbox' window appears over the top level window.

Instead of clicking a button, of course, the 'toolbox' would be exposed
on a top level window's expose event.

It's up to the application to manage the positioning of the 'toolbox' and
remember the coordinates relative to each top level window. Not a GTK
issue, really :-)
