AbstractMouseMode.java

    /**
     * Invoked from the MouseWheelListener
interface.
     */
    public
void mouseWheelMoved(MouseWheelEvent e) {
        int rot =
e.getWheelRotation();
        if
(e.getSource() instanceof MapBean) {
           
MapBean mb = (MapBean) e.getSource();
            if
(rot > 0) {
               
// Positive, zoom out
               
mb.zoom(new ZoomEvent(mb, ZoomEvent.RELATIVE, 1.1f));
            }
else {
               
mb.zoom(new ZoomEvent(mb, ZoomEvent.RELATIVE, .9f));
            }
        }
