Painting components to buffers

Question

Hi,
My class, GamePanel, is extending JPanel and implementing Runnable, therefore all my painting is done in run(). I am using a buffer to draw images on, I would also like to draw Component�s on it as well. Here is the code I�m using to draw the Component�s:
From gameRender()
// Get all the components
Component[] comms=this.getComponents();
// Go round all
for (int i=0;i<comms.length;i++)
System.out.println("Swing component name: "+comms.getName());
     // Paint it on here
     comms[i].paint(g);
Where g is the BufferedImage.getGraphics().
Then in another method also call from run(), the buffer is drawn on it the panel.
From paintScreen()
// Get the graphics from the panel
Graphics g=super.getGraphics();
// If the graphic and the buffer are not null
if (g!=null&&buffer!=null)
     // Draw the buffer
g.drawImage(buffer,0,0,null);
// Sync the display
Toolkit.getDefaultToolkit().sync();
// Dispose of the graphics
g.dispose();However, no components are painted.
Is there any way this can be done?
Thanks
Luke

I�ve managed to do something that seems to work now:
protected void paintScreen()
     try
          // Get the graphics from the panel
          Graphics g=super.getGraphics();
          // If the graphic and the buffer are not null
          if (g!=null&&buffer!=null)
               // Draw the buffer
               //g.drawImage(buffer,0,0,null);
               paintComponent(g);
          // Sync the display
          Toolkit.getDefaultToolkit().sync();
          // Dispose of the graphics
          g.dispose();
     } catch (Exception ex) {}
protected void paintComponent(Graphics g)
     if (buffer!=null)
          // Get the buffer graphics
          Graphics bufG=buffer.getGraphics();
          // Paint the border to the buffer
          super.paintBorder(bufG);
          // Paint the children to the buffer
          super.paintChildren(bufG);
          // Draw the buffer
          g.drawImage(buffer,0,0,null);
}I should properly dispose of bufG in panitComponent(), and I�m not sure how proper it is as the tutorials did advise against invoking the paintBorder() and paintChildren().
The other thing I need to do I the class is tiling of the image, I thought I mencion that here instead of starting a new thread.
I have a class, Backdrop, that draws an image using a start Point object, each time a call to moveXxx() is made, the start point is translated, - or + depeding on the direction.
At the moment, the image is drawn onto the background colour, but I would like to tile that image over the screen to fill in the gaps, if you see what I mean.
One idea I did have is , each time draw() is called, to move the start point, in intervals of image width and height, until both the x and y or less then or equal to 0, this would put the image into the top left hand corner, perhaps further depending on where the point started out. Once the image is in the corner, some kind of loop can be used to draw it up and down the owner panel.
What do you think? I just came up with that while writing.
