/** A widget used to choose from a list of items.
 *
 * A ComboBox is a widget that allows the user to choose from a list of valid choices. The ComboBox displays the 
 * selected choice. When activated, the ComboBox displays a popup which allows the user to make a new choice. The 
 * style in which the selected value is displayed, and the style of the popup is determined by the current theme. 
 * It may be similar to a OptionMenu, or similar to a Windows-style combo box.
 *
 * The ComboBox uses the model-view pattern; the list of valid choices is specified in the form of a tree model, 
 * and the display of the choices can be adapted to the data in the model by using cell renderers, as you would in 
 * a tree view. This is possible since ComboBox implements the CellLayout interface. The tree model holding the 
 * valid choices is not restricted to a flat list, it can be a real tree, and the popup will reflect the tree 
 * structure.
 *
 * The ComboBox widget looks like this with has_entry = false:
 * @image html combobox1.png
 *
 * The ComboBox widget looks like this with has_entry = true:
 * @image html comboboxentry1.png
 *
 * See also ComboBoxText, which is specialised for a single text column.
