Package uk.ac.starlink.topcat.plot2

Class GuiNavigationListener<A>

  • All Implemented Interfaces:
    java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.MouseWheelListener, java.util.EventListener
    public abstract class GuiNavigationListener<A>
extends uk.ac.starlink.ttools.plot2.NavigationListener<A>
    Abstract NavigationListener subclass that works with a PlotPanel. The main thing it does is arrange for progress logging where required. The only time this is required is when a data pos iterator is used in handling (re-center) click events. That is generally only for 3d plots. But it's harmless to use this wrapper in any case.
