Some questions on double buffering and expose in gtk2.

Hi Folks,

How does the double buffering in gtk2 work when dealing with drawables?

After drawing to a gtk-drawable, expose events are generated when part of
the drawable is unobscured. What should I do with these? For gtk 1.2 I
connected an expose event handler to a void callback and
just redrew the exposed rectangle. This doesn't seem to work consistently
in gtk2. I get regions of blank areas in drawables.

I guess it's because of the double buffering in gtk2.

So what is the right way to handle expose events for gtk2? Is this
documented somewhere? Where?

Thanks very much!
