If i have a drawingarea and an offscreen pixmap how do i simulate 
an exposure event when user clicks on a button ? 
the button's function is drawing in offscreen pixmap and changes re not visible
until i move other window over the drawing area or i minimize / maximize the main window ...

regards,
Mihai Moldovanu
