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.
Hide MXML SyntaxThe <mx:FileSystemComboBox> tag inherits all of the tag
attributes of its superclass and adds the following tag attributes:
