Class MouseTracker

java.lang.Object

java.awt.event.MouseAdapter

javax.swing.event.MouseInputAdapter

org.docx4j.org.xhtmlrenderer.swing.MouseTracker

All Implemented Interfaces:

MouseListener, MouseMotionListener, MouseWheelListener, EventListener, MouseInputListener

public class MouseTracker
extends MouseInputAdapter

A MouseTracker is used to delegate mouse events to the FSMouseListener instances associated with a BasicPanel. The tracker will start receiving events as soon as the first listener is added (via addListener(FSMouseListener) and will stop receiving events as soon as the last listener is removed via removeListener(FSMouseListener). This binding is handled automatically via the add and remove methods and the tracker will remain active as long as the tracker has at least one listener. The MouseTracker is also responsible for using MouseEvent coordinates to located the Box on which the mouse is acting.
