If the goal is to create an offscreen buffer to later be blitted to a window, you can modify line 1 & 2 to read 1. cnx->pixmap = gdk_pixmap_new(GDK_DRAWABLE(cnx->window->window), 2. cnx->data.header.width, cnx->data.header.height, -1); PS, this also shows that cnx->window is a confusing name, perhaps cnx->widget would work better. -Jim _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
