My suggestion is to also put clear instructions for building a Group in the Description section of http://fltk.org/documentation.php/doc-1.1/Fl_Group.html#Fl_Group It could read like this: "When adding child widgets to a Group take care to surround the childs with begin() and end(): Fl_Group::Fl_Group(x, y, w, h, label) { begin() ...add your widgets here end() } CAUTION: forgetting the end() statement leads to serious application misbehaviour that is hard to debug! > > I'll made an STR #1718. > http://fltk.org/str.php?L1718 > > Anyone want to take a shot at what the intro docs should say > about this?
