public abstract class ListItemHoverBehavior
extends AbstractObjectHoverBehavior<javax.swing.JList,java.lang.Object>

Abstract behavior that provides hover events for JList items. To install this behavior you will need to add it as MouseListener, MouseMotionListener and ComponentListener into the list, otherwise it will not function properly.

It uses mouse enter/exit/move events and component resized/moved/shown/hidden events to track hover index. It might seem excessive, but simple move listener does not cover whole variety of possible cases when hover index can be changed.
