(Afterthoughts: I was wondering if C++ has a way to implicitly convert from one class type, example a composite widget type, to another class, example Gtk:Widget&, simply by placing the class object in the context of needing a different class type, example Gtk::Widgets?  I was doing this above using functor operator.  So far I can only find examples of doing this with built in variable types like int or char*.)

Of course. Use a conversion operator.

operator Gtk::Widget&()
{

   return m_whatever_widget;

}
