                                               ComboBoxWithoutValuePattern

A combo box without the Value pattern. UIA combo boxes don't necessarily support the Value pattern unless they take arbitrary text values. However, NVDA expects combo boxes to have a value and to fire valueChange events. The value is obtained by retrieving the selected item's name. The valueChange event is fired on this object by ListItem.event_stateChange.
