Constructor Detail

ZoomPanMouseModule

public ZoomPanMouseModule(DasCanvasComponent parent,
                          DasAxis horizontalAxis,
                          DasAxis verticalAxis)

Creates a new instance of ZoomPanMouseModule

Method Detail

mouseWheelMoved

public void mouseWheelMoved(java.awt.event.MouseWheelEvent e)

mouse wheel events zoom or pan rapidly. With a physical wheel, I (jbf) found that I get 17ms per click, and this is managable. With a touchpad on a mac, these events come much faster, like 10ms per click, which can disorient the operator. So we limit the speed to 20ms per click, for now by dropping rapid clicks.
