scrollpane to the figure
===

I wanted to add one scrollbar into the RoundedRectangle. I have 3 Rounded rectangle in the root figure. Now I want to add scrollbar to each of the rounded rectangle. Is it possible to 
add the scrollbar to the rounded rectangle or rectangle figure? I used the following way . But it does not show any figure to  me. How to make it work? In the below example, I have added only one rectangle. 



    import org.eclipse.draw2d.ColorConstants;
    import org.eclipse.draw2d.Figure;
    import org.eclipse.draw2d.FigureCanvas;
    import org.eclipse.draw2d.LightweightSystem;
    import org.eclipse.draw2d.RoundedRectangle;
    import org.eclipse.draw2d.ScrollPane;
    import org.eclipse.draw2d.XYLayout;
    import org.eclipse.draw2d.geometry.Rectangle;
    import org.eclipse.swt.SWT;
    import org.eclipse.swt.layout.FillLayout;
    import org.eclipse.swt.widgets.Canvas;
    import org.eclipse.swt.widgets.Display;
    import org.eclipse.swt.widgets.Shell;
    
    public class RoundedRectangleTest {
    
    	public static void main(String args[]) {
    
    		Display display = new Display();
    		Shell shell = new Shell(display);
    		shell.setLayout(new FillLayout());
    		shell.setText("Scrollpane Example");
    
    		// Create a root figure and simple layout to contain all other figures
    		Figure root = new Figure();
    		root.setFont(shell.getFont());
    		root.setLayoutManager(new XYLayout());
    
    		ScrollPane scrollPane = new ScrollPane();
    
    		RoundedRectangle r = new RoundedRectangle();
    		r.setBackgroundColor(ColorConstants.yellow);
    		Rectangle rect = new Rectangle(10, 10, 50, 50);
    		r.setBounds(rect);
    
    		scrollPane.setContents(r);
    
    		root.add(scrollPane);
    
    		FigureCanvas canvas = new FigureCanvas(shell, SWT.DOUBLE_BUFFERED);
    		canvas.setBackground(ColorConstants.white);
    		//canvas.setContents(scrollPane);
    		LightweightSystem lws = new LightweightSystem(canvas);
    		lws.setContents(root);
    
    		shell.setSize(400, 350);
    		shell.open();
    		while (!shell.isDisposed()) {
    			if (!display.readAndDispatch()) {
    				display.sleep();
    			}
    		}
    		display.dispose();
    
    	}
    
    }
