Hi,
In my application, when I double click an editpart in diagram, the figure
should switch between an ellipse and a rectangle, how can I do this with two
separate figure?

Wishes

This should help you get on your way: preformRequest gets called
whenever the user double clicks on the figure with a request of type
REQ_OPEN.

Implement this in your editpart.

public void performRequest(Request req)
{
if (req.getType() == RequestConstants.REQ_OPEN)
{
IFigure fig = getFigure();
if(fig instanceof RectangleFigure)
{
Ellipse el = new Ellipse();
el.setSize(new Dimension(100, 100));
el.setBackgroundColor(ColorConstants.red);

((GraphicalEditPart)getParent()).getFigure().remove(fig);
setFigure(el);
((GraphicalEditPart) getParent()).getFigure().add(el);
}
else if (fig instanceof Ellipse)
{
RectangleFigure rect = new RectangleFigure();
rect.setSize(new Dimension(100,100));
rect.setBackgroundColor(ColorConstants.blue);

((GraphicalEditPart)getParent()).getFigure().remove(getFigur e());
setFigure(rect);
((GraphicalEditPart) getParent()).getFigure().add(rect);
}
refreshVisuals();

}

Regards,
Angel

Yikes, that's dangerous. Better would be that you return a simple Figure
object with a stack layout from your createFigure() method. You can then
switch between setting the ellipse and rectangle as the child of this
figure.
