My host is Linux machine. What I want is very simple, I have a background picture in the window, and for some reason I do not want to redraw the whole background picture, and only just redraw the partial region of the image. How can I implement it? Thanks. Best regards, Leo _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
