Using GLG2D in an existing application

From.java

  // all painting is done to this single JComponent (or subclass)
  JComponent paintingCanvas = new JComponent() {
    public void paintComponent(Graphics g) {
      super.paintComponent(g);

      // paint the scene to the Graphics object
    }
  };

  JFrame frame = // ...
  frame.setContentPane(paintingCanvas);

  // add an animator to paintingCanvas
  // ...

To.java

  JComponent paintingCanvas = new JComponent() {
    public void paintComponent(Graphics g) {
      super.paintComponent(g);

      // paint the scene to the Graphics object
    }
  };

  // if all painting is done to the single JComponent above
  // then
  paintingCanvas = new G2DGLCanvas(paintingCanvas);

  // else if paintingCanvas has a hierarchy of Swing components added to it
  // then
  paintingCanvas = new G2DGLPanel(paintingCanvas);
  // this handles the RepaintManager issues of subcomponents, but is not as stable or as fast

  JFrame frame = // ...
  frame.setContentPane(paintingCanvas);

  // add an animator to the new paintingCanvas
  // ...
