hi, I'm using the overlay in Fl_Overlay_Window to draw on a background image. At each redraw I only need to add a bit more information and don't want to redraw the entire overlay. So can I restrict the overlay so it doesn't clear the previous state? Perhaps with clipping?
The reason I want to do this is the overlay currently flickers during the update on some computers. Would this happen when there is no overlay hardware support? thanks, Richard _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
