*
* Note that you can not use this class with Gnome::Glade::Xml::get_widget_derived() to wrap a GtkComboBox added
* in the Glade user interface designer, because Glade adds its own TreeModel instead of using the TreeModel from
* this class. You could use a normal Gtk::ComboBox instead, though you can not use Glade to add rows to a TreeModel
* that is defined in your C++ code.
