		tree.addListener(<span style="color:#ff0000;">SWT.MouseDoubleClick</span>,new Listener() {
			@Override
			public void handleEvent(Event event) {
				Point point = new Point(event.x, event.y);
				TreeItem item = tree.getItem(point);
				
				if(<span style="color:#ff0000;">"TreeItem {TestTask.typ}"</span>.equals(item.toString()))
				{
					MessageDialog.openInformation(tree.getShell(), "TestTask.typ", "double click" + item);
				}
				
			}
		});
