I found an interesting link:

"You are probably doing all the changes within a function without 
returning control to gtk_main(). This may be the case if you do some 
lengthy calculation in your code. Most drawing updates are only placed 
on a queue, which is processed within gtk_main(). You can force the 
drawing queue to be processed using something like:

while (g_main_context_iteration(NULL, FALSE));

inside you're function that changes the widget.

What the above snippet does is run all pending events and high priority 
idle functions, then return immediately (the drawing is done in a high 
priority idle function)." [http://www.gtk.org/faq/#AEN602]

I don't see how i can call g_main_context_iteration in ruby. Any idea?

Thanks,
