hello I think that my plotting of points on Gtk::DrawingArea derived object are a bit of slow: I need a black background, so I'm drawing a black square that fills all Gtk::DrawingArea; I need color points, so I'm plotting it over the black square; I put a timer that calls Gtk::DrawingArea::queue_draw() every few miliseconds !!!; That is, each timer iteration, my Gtk::DrawingArea derived object must to be updated and perform these 3 operations... can I improve that ??? ( see attached file ) thanks __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
