Simple code copied from the draw2d sample:

import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Display;
import org.eclipse.draw2d.*;
import org.eclipse.swt.SWT;
import org.eclipse.draw2d.geometry.*;

public class Test1 {
public static void main(String args[]){
Shell shell = new Shell();
shell.open();
shell.setText("Draw2d");
LightweightSystem lws = new LightweightSystem(shell);
lws.getRootFigure().setBackgroundColor(ColorConstants.white) ;
IFigure panel = new Panel();
panel.setLayoutManager(new FlowLayout());
lws.setContents(panel);

Clickable button = new Button("Click me");
Clickable checkbox = new CheckBox("Check box");

Shape ellipse = new Ellipse();
ellipse.setBackgroundColor(ColorConstants.darkBlue);
ellipse.setOpaque(true);
Shape rectangle = new RectangleFigure();
rectangle.setBackgroundColor(ColorConstants.lightBlue);
rectangle.setOpaque(true);

panel.add(button);
panel.add(checkbox);
panel.add(ellipse);
panel.add(rectangle);

Display display = Display.getDefault();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ())
display.sleep ();
}
}
}

I can't see the ellipse and rectangle?

Do you not have to setSize() first?
e.g

Shape ellipse = new Ellipse();
ellipse.setSize(15,15);
ellipse.setBackgroundColor(ColorConstants.darkBlue);
ellipse.setOpaque(true);
Shape rectangle = new RectangleFigure();
rectangle.setBackgroundColor(ColorConstants.lightBlue);
rectangle.setSize(15,15);
rectangle.setOpaque(true);

Thank you!

but that code can run under previous version, that is funny! It must be
something changed in the newer version!
