[news.eclipse.platform.swt] Adding Images Dynamically on button click

[august.raghu@xxxxxxxxx (Raghu)]

Hi,

I took sample snippet 
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet275.java?view=co 

and trying to add image on button click instead of timer, am not able to 
do so. 

Code:


	xpos = 10;
	ypos = 10;
	
	
	canvas.addListener (SWT.Paint, new Listener () {
		public void handleEvent (Event event) {
			value = "Hello"+xpos;
			event.gc.drawImage (image, xpos,ypos);
			event.gc.drawString (value, xpos+5, ypos+5, true);
		}
	});



	Button button = new Button(shell, SWT.PUSH);
	button.setText("Add Image");
	button.addSelectionListener(new SelectionListener(){

		public void widgetSelected(SelectionEvent arg0) {
			if (canvas.isDisposed ()) return;
			// canvas.redraw (); // <-- bad, damages more than is needed
			GC gc = new GC (canvas);
			gc.dispose ();
			xpos = xpos+150;
			canvas.redraw (xpos, ypos, 100, 30, false);
		}

		public void widgetDefaultSelected(SelectionEvent arg0) {
			// TODO Auto-generated method stub
			
		}
		
	});


Need help in this regards.


Thanks,
Raghu
