Double Buffering

Hey guys,

I've seen all the chat on double buffering, yet having followed the guidelines my scribble application still flickers really badly. Here is the paint method:

Code:

---

@Override
        public void paintControl(PaintEvent arg0)
    {
               
                Image bufferImage = new Image(s.getDisplay(), s.getBounds());

        GC gcImage = new GC(bufferImage);
       
        // Draw the background
        gcImage.setBackground(arg0.gc.getBackground());
        gcImage.fillRectangle(bufferImage.getBounds());
               
        // draw the stack of points I have been collecting from mouse events
                for (int i =0;i<(l.size()-1);i++)
                {
                        gcImage.drawLine(l.elementAt(i).x, l.elementAt(i).y,l.elementAt(i+1).x,l.elementAt(i+1).y);
                }
               
                // draw the buffered image to the screen
                arg0.gc.drawImage(bufferImage, 0, 0);
               
                // Clean up
        bufferImage.dispose();
               
        }

Any ideas why?

Think I've sorted this, it seems the OS was redrawing the background when I was doing that too...so creating a shell with SWT.NO_BACKGROUND as a parameter in the constructor was the solution
