In FLTK, *any* widget can have a box around itself by simply calling myWidget->box(FL_SOME_BOXTYPE); . The Fl_Box widget is simply a widget with no additional function than having a box and a label. It does not handle any events that occur within the area of the box. You code is wrong because you draw your button under the box. That way, the button gets drawn first, then the box (which can be a frame only, but also have a background), erasing you button again. The sme overlapping happens to any event that may got to the box. The solution is simple: never overlap widgets. Instead, put the Button inside a group, and give the group the box style that you like. The group will correctly draw your button and forward all events. ---- http://robowerk.com/ _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
