Adds the specified hierarchy listener to receive hierarchy changed events from this component when the hierarchy to which this container belongs changes.

Usage

From source file:JSplitPaneVerticalSetTopBottom.java

public static void main(String[] a) {
    JFrame horizontalFrame = new JFrame();
    horizontalFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JComponent topButton = new JButton("Left");
    JComponent bottomButton = new JButton("Right");
    final JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);

    HierarchyListener hierarchyListener = new HierarchyListener() {
        public void hierarchyChanged(HierarchyEvent e) {
            long flags = e.getChangeFlags();
            System.out.println(e.getSource());
            if ((flags & HierarchyEvent.SHOWING_CHANGED) == HierarchyEvent.SHOWING_CHANGED) {
                splitPane.setDividerLocation(.75);
            }/*from  w w  w  .  j  av a 2  s .  c  o m*/
        }
    };
    splitPane.addHierarchyListener(hierarchyListener);

    splitPane.setTopComponent(topButton);
    splitPane.setBottomComponent(bottomButton);

    horizontalFrame.add(splitPane, BorderLayout.CENTER);
    horizontalFrame.setSize(150, 150);
    horizontalFrame.setVisible(true);
