javax.swing
interface ComboBoxModel

All Superinterfaces:: ListModel

All Known Implementing Classes:: MetalFileChooserUI.DirectoryComboBoxModel, MetalFileChooserUI.FilterComboBoxModel

public interface ComboBoxModel
extends ListModel

A data model for a combo box. This interface extends ListDataModel 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.

Method Summary
`Object`	`getSelectedItem()` Returns the selected item
`void`	`setSelectedItem(Object anItem)` Set the selected item.
