Classes which implement this interface provide methods that deal with the events that are generated as the mouse pointer passes (or hovers) over controls.
After creating an instance of a class that implements this interface it can be added to a control using the addMouseTrackListener method and removed using the removeMouseTrackListener method. When the mouse pointer passes into or out of the area of the screen covered by a control or pauses while over a control, the appropriate method will be invoked.
