Yep. > So, to put your widget on top of the z-order, it needs to be last in the > array. > > To achieve this I guess you need to remove it from the scroll, then add > it back in - this might get it to the end of the list? > > I guess this is effectively what Michael's code does, but by > manipulating the widget list directly... If this is the only problem, then it is actually *much* easier: group->insert(widget,group->children()); group->redraw(); This will put the widget into the group as the last child. You don't need to mess around with array() or (much worse) with the scrollbars for Fl_Scroll. They will be adjusted when draw() is called. See the docs at: http://www.fltk.org/doc-1.1/Fl_Group.html#Fl_Group.insert "The widget is removed from it's current group (if any) and then inserted into this group. It is put at index n (or at the end if n >= children(). This can also be used to rearrange the widgets inside a group."
