Imitating the add() function without actually adding a Applet object

Question

Okay, I have an instance of an object that ultimately extends Applet (not JApplet). I want this applet to paint itself onto another instance of JFrame without adding (performing the add(component) method) the applet instance.
Note though that if I do add the applet to the JFrame, the object is painted correctly and everything works fine. But for some reasons specific to me (that I don't want to go into details with), I do not want to add the applet.
I would want to do something like this:
Applet instance = /* my instance */
JFrame frame = /* my frame */
JPanel pane = new JPanel(new BorderLayout()) {
  public void paint(Graphics g) { instance.paint(g) }
  public void update(Graphics g) { instance.update(g) }
frame.add(pane);Using the above concept, the frame doesn't get any painting. Exactly what does the add method do that I'm not imitating here? I've tried looking through the source and I don't see much changing of the actual instance. I also tried setting the parent of the applet (using reflect) to my JPanel (above example), but that did nothing. I tried doing that since I thought the applet may have uses the getGraphics() method for getting a graphics to draw with. BTW, I do not have source code to the Applet instance: I'm trying to make this dynamic.
Thanks in advance for any support

Answer 1

There are 2 problems I can think of:
1. Calling paint on heavyweight components does no drawing to the graphics object. You can see this if you try to use the java print API to print a heavyweight button or something
2. I'm not sure that calling paint on Applet causes the applets children to get drawn.
Your best bet might be to use the java.awt.Robot, do a screen scrape of your applet and then draw that in your frame.
