Constructor Detail

BoxZoomMouseModule

public BoxZoomMouseModule(DasCanvasComponent parent,
                          DataSetConsumer consumer,
                          DasAxis xAxis,
                          DasAxis yAxis)

Creates a new instance of BoxZoomMouseModule

Parameters:

parent - component who owns the mouse module

consumer - is the source context of the data set selection

xAxis - the plot's xaxis.

yAxis - the plot's yaxis.

Method Detail

zoomBox

protected void zoomBox()

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.

Specified by:

mouseWheelMoved in interface java.awt.event.MouseWheelListener

Overrides:

mouseWheelMoved in class MouseModule

Parameters:

e -

mouseRangeSelected

public void mouseRangeSelected(MouseDragEvent e0)
