public class RotatingGraphMousePlugin extends AbstractGraphMousePlugin implements MouseListener, MouseMotionListener
RotatingGraphMouse provides the abiity to rotate the graph using the mouse. By default, it is activated by mouse button one drag with the shift key pressed. The modifiers can be overridden so that a different mouse/key combination activates the rotation
