Class ViewTranslatingGraphMousePlugin

java.lang.Object

org.jungrapht.visualization.control.AbstractGraphMousePlugin

org.jungrapht.visualization.control.ViewTranslatingGraphMousePlugin

All Implemented Interfaces:

MouseListener, MouseMotionListener, EventListener, GraphMousePlugin

public class ViewTranslatingGraphMousePlugin
extends AbstractGraphMousePlugin
implements MouseListener, MouseMotionListener

ViewTranslatingGraphMousePlugin uses a MouseButtonOne press and drag gesture to translate the graph display in the x and y direction by changing the AffineTransform applied to the Graphics2D. The default MouseButtonOne modifier can be overridden to cause a different mouse gesture to translate the display.
