/*  ComboboxEntry Example
 *
 *  This example creates a comboboxentry with a single list of text strings that can
 *  be edited. It uses Gtk::ComboBoxEntry and creates the model itself. Alternatively,
 *  it could use the convenience class Gtk::ComboBoxEntryText which creates the model
 *  for you. 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.
