Proxy Pattern, integrate JXLayer + JHotDraw

editor = new DefaultDrawingEditor();
// editor.add(this.defaultDrawingView);
editor.add(this.chartLayerUI);
// All toolbar creation based on editor.
// ...
// ...
this.chartLayerUI.setDrawing(createDrawing());
final org.jdesktop.jxlayer.JXLayer<ChartPanel> layer = new org.jdesktop.jxlayer.JXLayer<ChartPanel>(this.chartPanel);
this.chartLayerUI = new ChartLayerUI<ChartPanel>(this);
layer.setUI(this.chartLayerUI);
// JxLayer being added in to application, not JHotDraw's defaultDrawingView.
// Whenever JXLayer receive mouse event, it will forward the event to defaultDrawingView.
// In the painting event of JXLayer, it will trigger JHotDraw's defaultDrawingView paintComponent as well.
getContentPane().add(layer, java.awt.BorderLayout.CENTER);

public class ChartLayerUI<V extends javax.swing.JComponent> extends AbstractLayerUI<V> {

public class ChartLayerUI<V extends javax.swing.JComponent> extends AbstractLayerUI<V> implements DrawingView, EditableComponent {

    private final org.jhotdraw.draw.DefaultDrawingView view = new org.jhotdraw.draw.DefaultDrawingView();
    @Override
    public Drawing getDrawing() {
        return this.view.getDrawing();
    }
    @Override
    public void setDrawing(Drawing arg0) {
        this.view.setDrawing(arg0);
    }
.....

    private void retargetMouseEvent(MouseEvent e) {        
        MouseEvent me = SwingUtilities.convertMouseEvent(this.view, e, this.view);
        System.out.println("retarget mouse event " + me);
        this.view.dispatchEvent(me);
    }
    @Override
    protected void processMouseEvent(MouseEvent e, JXLayer<? extends V> layer) {
        super.processMouseEvent(e, layer);
        retargetMouseEvent(e);
        this.processEvent(e, layer);
    }
    @Override
    protected void processMouseMotionEvent(MouseEvent e, JXLayer<? extends V> layer) {
        super.processMouseMotionEvent(e, layer);
        retargetMouseEvent(e);
        this.processEvent(e, layer);
    }





Whenever receive a graphics object during pain event, forward the graphics object to defaultDrawingView as well.
[code]
    protected void paintLayer(Graphics2D g2, JXLayer<? extends V> layer) {
        super.paintLayer(g2, layer);
        this.view.paintComponent(g2);
        ....
[/code]
This work pretty fine as :
(1) When I click on the toolbar and click on JXLayer area, the figures can be seen immediately
(2) When I click on drag the figures, the figure can move around
(3) When I click and drag on Text figure right side, the text area can resize
(4) When I click and drag on Text figure left side, the font size can resize
What the shortcoming is :
(1) When I move my mouse across the figure, the cursor is not turning into hand cursor. I do some println, the mouse move event is already forwarded to defaultDrawingView, but how come the cursor is not turning into hand cursor?
(2) I click on a figure, there are no sign indicated the figures is being selected (There should be 4 small rectangles around the figure to indicate it is being selected). Again, the mouse click event is already forwarded to defaultDrawingView.
Is there any other hacks I had missed out?
