Re: [gtk-list] gdk_set_back_pixmap and GtkDrawingArea

On 29 Jun, Maciej Stachowiak shouted:
->  
->  I'm trying to make a drawing area widget update faster by setting my
->  backing pixmap as its background pixmap, by using gdk_set_back_pixmap
->  on the widget's window field. However, this has two problems. First,
->  the pixmap is not drawn in the background initially; the background is
->  just set to an apparently random color from the pixmap. However,
->  dragging another window over my app exposes the pixmap. Second, when I
->  draw something to the pixmap, it does not get updated, again until I
->  drag another window over it so it gets exposure events. Am I totally
->  misunderstanding how background pixmaps are supposed to work?

when u've finished drawing on the pixmap call gdk_clear_window(); also
do this just after setting the bg pixmap too :)
