[news.eclipse.platform.swt] adding event to a line

[caesar <caesarkim@xxxxxxxxxxx>]

I am trying to adding an event to a line so that I can drag a line on composite.

Here is my code.


	    final Composite composite = new Composite(scomposite, SWT.NONE);
	    Color backgroundColor = new Color(composite.getDisplay(), 246, 160, 11);
	    scomposite.setContent(composite);
	    composite.setLayout(null);
	    composite.setSize(editorWidth, editorHeight);
	    composite.setBackground(backgroundColor);
	    composite.addPaintListener(new PaintListener() {
		public void paintControl(PaintEvent e) {
		    e.gc.drawLine(Constants.LEFT_XCOORDINATE, Constants.LEFT_YCOORDINATE, Constants.HORIZONTAL_WIDTH, 20);
		    e.gc.drawLine(20, 20, 20, 
		}
	    });


Is there a way to make a draggable line?  I want a user to drag a line on a composite. It would be a great help if anybody tells me an alternative way to do it.

Please help.

Thanks.
