How to register mouselistener for custom class?

Question

i m trying to create a custom class (extending java.awt.Rectangle)which responds to mouse gestures.
i m using it as an object on my drawpad which responds to mouse behavior
like rollover.
the rollover color change is achieved using canvas' graphics object triggerd by my cutom class
i m not able to register a mouseevent for the custom class.
can someone help me in achieving this?
thanks in advance

Something like this? Don't think I'd be likely to extend Rectangle, myself, but anyway...
public class HotSpot extends Rectangle implements MouseMotionListener
    private boolean hover = false;
    // add constructors to taste
    public void mouseMoved(MouseEvent e)
        if (this.hover != (contains(e.getX(), e.getY())
            this.hover = ! this.hover;
            if (this.hover)
                // "mouse enter" code here
            else
                // "mouse exit" code here
    public void mouseDragged(MouseEvent e)
}Obviously you'd need something like this elsewhere,
myDrawingPad.addMouseMotionListener(new HotSpot(...));
