Your example below says "parent()", which is not necessarily the same as parent window == "window()".

Whether or not it's reliable ... that depends on what you call reliable. IMHO parent()->redraw() will draw the entire parent group with all children. This will also draw the parent group's background. So far, so good, but if (a) the parent group doesn't have a background (FL_FRAME_BOX or FL_NO_BOX), or (b) the label overlaps the parent group's border(s), then this wouldn't work as expected. Is this "reliable" enough? OTOH, if you call window()->redraw(), then this would reliably draw everything, but might flicker, if you don't use double buffering (Fl_Double_Window).
