	btn_stop.addMouseListener(new MouseAdapter() {   
            public void mouseClicked(MouseEvent event) {  
                 print("do click");

新建有滚动条的 输入框

	JMenuBar jb;
	JTextArea ja;
	JScrollPane jsp;

	public Index(){
		jb = new JMenuBar();
		this.setJMenuBar(jb);
		ja = new JTextArea();
		jsp = new JScrollPane(ja);
		this.setSize(600, 400);
		this.setLayout(new BorderLayout());
		this.add(jsp);
		this.setVisible(true);
	  
	}
