Thanks. I tested the widget and it gets FL_PUSH and if I return 1 for it, then the widget gets the FL_DRAG. What I'm trying to do is get the FL_MOVE which, IIRC, occurs when the mouse simply enters the bounds of the widget. I tried returning 1 for the FL_ENTER event, but that didn't make FL_MOVE appear. -- Alvin _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
