Runtime Versions : AIR 1.1

The FileSystemComboBox control defines a combo box control for navigating up the chain of ancestor directories from a specified directory in a file system. You often use this control with the FileSystemList and FileSystemTree controls to change the current directory displayed by those controls.

Unlike the standard ComboBox control, to populate the FileSystemComboBox control's dataProvider property, you set the directory property. This control then automatically sets the dataProvider property to an ArrayCollection of File objects that includes all the ancestor directories of the specified directory, starting with the COMPUTER File and ending with the specified directory.

When you select an entry in the dropdown list, this control dispatches a change event. After the event is dispatched data provider, and consequently the dropdown list, contain the selected directory's ancestors.
