请教一个JLabel问题，谢谢大家

Question

想让图缓慢移动.在LABEL   中放入图,   在   onCLICK   事件用:    
      for(i=259;i>2;   i--){    
          Thread.sleep(200);    
          Label1.setLocation(i,69);    
      }    
     
  但LABEL   不移,等待一会后,一下就移到终点,如何解决? 谢谢大家

把代码改成这样的(注意,其中的label应该是成员变量或声明为final类型):       new Thread(new Runnable(){
            public void run(){
                for(int i =240;i>2;i--){
                    try{
                        Thread.sleep(200);
                    }catch(Exception ex){
                        //do nothing
                    }
                    final int x = i;
                    SwingUtilities.invokeLater(new Runnable(){
                        public void run(){
                            label.setLocation(x,69);
                        }
                    });
                }
            }
        }).start();
