Sorry, I meant pixmaps, not pixbufs. http://library.gnome.org/devel/gdk/stable/gdk-Bitmaps-and-Pixmaps.html Pixmaps are held on the server side (whereas pixbufs are client-side). They are offscreen drawables and, on most systems, are very quick because the GPU can move them about. You'd link to the configure event to build the offscreen pixmap. The scribble example in the tutorial uses pixmaps to improve drawing: http://library.gnome.org/devel/gtk-tutorial/stable/c2422.html John _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
