doClick需要在调度线程上吗?

   public void doClick(int pressTime) {
        Dimension size = getSize();
        model.setArmed(true);
        model.setPressed(true);
        paintImmediately(new Rectangle(0,0, size.width, size.height));
        try {
            Thread.currentThread().sleep(pressTime);
        } catch(InterruptedException ie) {
        }
        model.setPressed(false);
        model.setArmed(false);
    }

谢谢。
