Well, the OP Mario, had an ultimate goal of using your scribble example (mouse drag drawing) to make selections on a foreign window. Off list, we have managed to draw to the drawing area, but as my example showed, no mouse events could be detected. BUT Mario did find a way to detect the foreign window mouse events by replacing the mainloop. See attachment for the example code. But there are glitches, like the main script buttons stopped working. Maybe you could see a way to improve the custom mainloop in the attachment to get it working? I tried sprinkling a bunch of Gtk2->main_iteration while Gtk2->events_pending; in all the callbacks, and seemed to help a bit, but it's not perfect. And you are right, this is just a stupid code trick, so please don't waste time on it, but if you see something obvious, we would appreciate it.
