I have seen code that do tiled fills by first blitting a source image (lets say 100x100 pixels) to pos (0, 0), then blitting rect (0,0,100,100) to (0,100,100,100), then (0,0,200,100) to (0,200,200,100) etc., effectively doubling the filled size with each blit. -- Christoph Feck http://kdepepo.wordpress.com/ KDE Quality Team _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
