* @extends widget
* The ComboBox is used to make a selection from a list of items.
* The ComboBox contains <code><item></code> tags each describing
* an entry in the selection list.
* @att type The selection method of the ComboBox. Can be one 'select', where
* the user can select items using either the mouse or the arrow keys, 'edit',
* where the user can write freely in the ComboBox in the same way as in a
* LineEdit during which it will present but not limit to the matching values
* of its list, and finally 'search', where the user can write in the ComboBox
* but is restricted to writing strings matching the items in the list.
* @att value [item] The value of the item. This will be the value of the
* ComboBox if this item is selected.
* @att caption [item] The caption of this item. This is the text presented
* to the user in the ComboBox.
