A few things: Calling classes "base" and "upper" is somewhat dangerous because these words are used in the standard libraries and may lead to confusion. But more importantly, you use multiple inheritance on you "upper" class. AFAIK a static_cast will not be sufficient to resolve the void pointer correctly. You could use a dynamic_cast instead (remember to enable RTTI). Personally, I try to avoid multiple inheritance... . ---- http://robowerk.com/ _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
