Try enclosing the creation of your openGL window with begin() and end() for the double window. So for instance if your Fl_Double_Window is called dwin, then: dwin.begin(); glwin = new Fl_Gl_Window(...); dwin.end(); This will ensure the gl window you create will be parented to the double window, instead of a separate window on its own. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
