Examples of javax.swing.event.AncestorListener

javax.swing.event.AncestorListener
AncestorListener Interface to support notification when changes occur to a JComponent or one of its ancestors. These include movement and when the component becomes visible or invisible, either by the setVisible() method or by being added or removed from the component hierarchy. @author Dave Moore
