Constructor Detail

VerticalRangeSelectorMouseModule

public VerticalRangeSelectorMouseModule(DasCanvasComponent parent,
                                        DasAxis axis)

Method Detail

getLabel

public java.lang.String getLabel()

Description copied from class: MouseModule

returns a human-readable string that identifies the module

Overrides:

getLabel in class MouseModule

Returns:

a human-readable string that identifies the module

create

public static VerticalRangeSelectorMouseModule create(DasPlot parent)

mouseRangeSelected

public void mouseRangeSelected(MouseDragEvent e0)

Description copied from class: MouseModule

Action to take when a mouse range (click, drag, release) has been selected. This is intended to be overridden.

Overrides:

mouseRangeSelected in class MouseModule

Parameters:

e0 - the drag event.

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 manageable. 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 -

addDataRangeSelectionListener

public void addDataRangeSelectionListener(DataRangeSelectionListener listener)

Registers DataRangeSelectionListener to receive events.

Parameters:

listener - The listener to register.

removeDataRangeSelectionListener

public void removeDataRangeSelectionListener(DataRangeSelectionListener listener)

Removes DataRangeSelectionListener from the list of listeners.

Parameters:

listener - The listener to remove.
