There is a copy-on-next-vert-refresh call in X, I think. Part of the dbe extension. I dont think I can use it with FLTK though, as I can't find a way of drawing onto an non-screen surface and then using the dbe. Its probably just a bad choice of toolkit. GDK and SDL seem to be able to do it. - Steve _______________________________________________ linux-audio-dev mailing list [EMAIL PROTECTED] http://music.columbia.edu/mailman/listinfo/linux-audio-dev
