- All Known Implementing Classes:
DefaultComboBoxModel,MetalFileChooserUI.DirectoryComboBoxModel,MetalFileChooserUI.FilterComboBoxModel
A data model for a combo box. This interface extends
ListModel
and adds the concept of a selected item. The selected item is generally
the item which is visible in the combo box display area.
The selected item may not necessarily be managed by the underlying
ListModel. This disjoint behavior allows for the temporary
storage and retrieval of a selected item in the model.
