private Diagram createDiagram() diagram = new Diagram(); RectangleShape rect = new RectangleShape(); rect.setX(100); rect.setY(100); rect.setWidth(80); rect.setHeight(60); diagram.addShape(rect); EllipseShape ellipse = new EllipseShape(); ellipse.setX(250); ellipse.setY(150); ellipse.setWidth(70); ellipse.setHeight(70); diagram.addShape(ellipse); return diagram;
