## Detailed Description

This is a specialisation of the ComboBox which has one column of text (a simple list), and appropriate methods for setting and getting the text.

You should not call set_model() or attempt to pack more cells into this combo box via its CellLayout base class.

Note that you cannot 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.
