/*  ComboboxText Example
 *
 *  This example creates a combobox with a single list of text strings.
 *  It uses the convenience class Gtk::ComboBoxText which replaces the
 *  deprecated Gtk::OptionMenu. A more advanced combobox example can be
 *  found in the <tests/combobox> subdirectory which shows you how to 
 *  add images and use the new combobox grid mode.
