You can inherit Fl_Scroll and override resize(X,Y,W,H) method. Each time window (and thus your scroll group widget) resizes, resize() will be called with new values. I would advise calling Fl_Scroll's resize too (in overriden method) so scrollbars can be nicely updated. -- Sanel _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
