Class TrackingAdjustmentListener

java.lang.Object
  org.apache.log4j.lf5.viewer.TrackingAdjustmentListener

All Implemented Interfaces:

AdjustmentListener, EventListener

public class TrackingAdjustmentListener
extends Object
implements AdjustmentListener

An AdjustmentListener which ensures that an Adjustable (e.g. a Scrollbar) will "track" when the Adjustable expands. For example, when a vertical scroll bar is at its bottom anchor, the scrollbar will remain at the bottom. When the vertical scroll bar is at any other location, then no tracking will happen. An instance of this class should only listen to one Adjustable as it retains state information about the Adjustable it listens to.
