Class ChangeTracker

java.lang.Object
  jgroup.experiment.gui.views.helpers.ChangeTracker

public class ChangeTracker
extends java.lang.Object

Utility class providing static methods for marking JLabels and tabs when their connected editable components change. The component must add a ChangeableActionListener as action listener, and pass the label and the panel to be marked in its constructor. ChangeTracker assumes the parent of the JPanel to be a JTabbedPane. The class also provides similar static methods for marking DefaultMutableTreeNodes in a tree. No listener is necessary for nodes.
