对Button而言，添加方法如下：
public class ClientLoginPanel extends JFrame implements ActionListener {/** * This method initializes jButton * * @return javax.swing.JButton */private JButton getJButton() {if (jButton == null) {jButton = new JButton();jButton.setBounds(new java.awt.Rectangle(247,180,216,33));jButton.setText("Login");jButton.addActionListener(this);}return jButton;}}//代码是节选的，不完整。请注意。???
