int	getSelectedIndex() Returns the selected index or `-1` if there is no selection.
boolean	isSelected() Returns `true` if there is a selection, and `false` otherwise.
void	removeChangeListener(ChangeListener listener) Deregisters a listener so that it no longer receives {@link ChangeEvent} notifications from this model.
