java.awt.event.HierarchyBoundsAdapter

An abstract adapter class for receiving ancestor moved and resized events. The methods in this class are empty. This class exists as a convenience for creating listener objects.

Extend this class and override the method for the event of interest. (If you implement the HierarchyBoundsListener interface, you have to define both methods in it. This abstract class defines null methods for them both, so you only have to define the method for the event you care about.)

Create a listener object using your class and then register it with a Component using the Component's addHierarchyBoundsListener method. When the hierarchy to which the Component belongs changes by resize or movement of an ancestor, the relevant method in the listener object is invoked, and the HierarchyEvent is passed to it. @author David Mendenhall @see HierarchyBoundsListener @see HierarchyEvent @since 1.3

        frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
        
        // Register a listener for when the window is resizing so that we can resize the 
        // internal frames. The HierarchyBoundsListener gets events while it is resizing,
        // whereas the ComponentListener only gets them after the resize.
        frame.getContentPane().addHierarchyBoundsListener(new HierarchyBoundsAdapter(){
            @Override
            public void ancestorResized(HierarchyEvent e) {
                // Start by checking that the internal frame will fit and adjust if required.
                PictureFrame pictureFrame = app.getPictureFrame();
                Dimension desktopSize = app.getDesktopPane().getSize();

        propListener = new PropertyChangeListener() {
            public void propertyChange(PropertyChangeEvent evt) {
                onPropertyChange(header, evt.getPropertyName(), evt.getOldValue(), evt.getNewValue());
            }
        };
        boundsListener = new HierarchyBoundsAdapter() {
            @Override
            public void ancestorResized(HierarchyEvent e) {
                if (header == e.getComponent()) {
                    View v = (View) descriptionPane.getClientProperty(BasicHTML.propertyKey);
                    // view might get lost on LAF change ...

                    }
                }
            }
        });


        addHierarchyBoundsListener(new HierarchyBoundsAdapter() {
            @Override
            public void ancestorResized(HierarchyEvent he) {
                if (isShowing()) {
                    onShownOrResized();
                }
