Eclipse Rap开发 异步刷新UI处理

btnNewButton.addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				
				new Thread(new Runnable(){

					@Override
					public void run() {
						try {
							Thread.sleep(3000);
						} catch (InterruptedException e) {
							e.printStackTrace();
						}
//						Display.getCurrent().asyncExec(new Runnable(){//null point current thread is not ui thread
						shell.getDisplay().asyncExec(new Runnable(){
							@Override
							public void run() {
								text.setText("我特么是异步的！！！？？？");
							}
						});
					}
					
				}).start();
			}
		});

container.getDisplay().timerExec(0, new Runnable(){
            @Override
            public void run() {
                display.timeExec(1000,this);
            }
        });
