Hi, I'm planning to make my app use cairo instead of GDK based functions. I'm using a drawing area, which draws into a pixmap when the "configure" event is emitted, and copies the relevant part of the pixmap back on the screen on the "expose" event.
When I'm doing the same with cairo, a black screen is the result. The ref. manual says in the FAQ that I should either turn off double buffering, or draw in the expose signal. This is also what the example testcairo (coming along with Gtk) does. I'm confused. Does this mean that drawing using cairo is slower since it has to redraw the whole thing again on each expose signal? Or is there some smart thing in Gtk that somehow knows that when the expose event is a result of a configure event, it doesn't really do the drawing but copies the invalidated part back?
