Class TabHistoryListener

java.lang.Object
  com.isti.util.gui.TabHistoryListener

All Implemented Interfaces:

java.util.EventListener, javax.swing.event.ChangeListener

public class TabHistoryListener
extends java.lang.Object
implements javax.swing.event.ChangeListener

Class TabHistoryListener is an implementation of 'ChangeListener' that can be added to a 'JTabbedPane' object to allow better control over which tab is selected after a tab is removed. It can be configured to have a "history" such that whenever a pane is removed the most recently selected pane is then selected; or so that the first tab is always selected. In most cases any exceptions that might occur are trapped, reported and discarded (as tab-selection is not considered to be "mission-critical").
