Class DispatchHandlerFX

java.lang.Object

org.jfree.chart.fx.interaction.AbstractMouseHandlerFX

org.jfree.chart.fx.interaction.DispatchHandlerFX

All Implemented Interfaces:

MouseHandlerFX

public class DispatchHandlerFX
extends AbstractMouseHandlerFX

Handles mouse move and click events on the ChartCanvas by dispatching ChartMouseEventFX events to listeners that are registered with the ChartCanvas (listeners can also be registered with a ChartViewer control).

THE API FOR THIS CLASS IS SUBJECT TO CHANGE IN FUTURE RELEASES. This is so that we can incorporate feedback on the (new) JavaFX support in JFreeChart.

Since:

1.0.18

void	handleMouseMoved(ChartCanvas canvas, MouseEvent e) Handles a mouse moved event.
