When I tried to create an offscreen buffer in the initialization of my widget, it would give me a segmentation fault. Sure enough, when I moved the code to the first draw, it would work just fine. So I'm assuming that offscreen buffers only work when FLTK is currently drawing, but I wonder why? After all, you're not drawing to a window or widget, you're drawing to an offscreen buffer that may or may not be related to one.
On a different note, is there a problem with drawing offscreen buffers onto themselves(with an offset)? This would be useful to speed up scrolling. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
