[pygtk] gtk.DrawingArea redraw problem.

[Germán Diago]

Hello. I'm using a derived gtk.DrawingArea to draw a pixbuf inside.
The problem is that if I put the drawing area before showing the
main window, the DrawingArea gets exposed. If I attach the DrawingArea
through a callback (after w.show_all() has been called) the widget does not
get exposed.
Could anyone help, please? I'm desperate, I tried everything possible,
googled and
googled and got no answer. By the
way, maybe this is a similar problem:

Thank you.
