Fl_Pack always reorders its children and lines them up. Then it resizes itself no larger than the outline of all children. This in turn is used by the Fl_Scroll to update the scroll bars. The actions of Fl_Pack are sometimes surprising in that they resize children horizontally (if the Pack is vertical) and reorder the children vertically. The best would be, if you could send us code that we can compile and test. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
