我正在尝试向我的程序添加一个侦听器，当单击面板时，它将打开一个新的 JFrame。例如 jpanel4 是面板标签消息。当我单击 jpanel4 时，我希望它打开 SendMessages JFrame，它是 SendMessages 类。

关于我需要走的方向有什么见解吗？这种方法甚至可行吗？

  public static void main(String args[])

    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {

private javax.swing.JTextArea jTextArea2;
// End of variables declaration                   
}

这就是我最终使用的。

       private class menuBarListener  implements MouseListener
  {
  public void mouseClicked(MouseEvent e)
  {
    String c = e.getComponent().getName();


    if (c.equals("MessagePanel"))
    {
     // opens the send message frame. //dispose(); closes the current frame
       SendMessage s = new SendMessage();
          dispose ();
     s.setVisible(true);

查看How to mouse listeners，但基本上

jpanel4.addMouseListener(new MouseAdapter() { 
    public void mouseClicked(MouseEvent evt) { 
        //...
    }
});
