I'm not sure if I understand your question correctly. But the answer is: no, there is no bounds check in FLTK for children within a group (Fl_Group or Fl_Scroll or whatever). You can even place child widgets completely outside of the parent group, but if you do so then redrawing and event delivery doesn't work. Fl_Scroll does this by design - the child widgets are usually in parts outside of the parent's bounds.
