如何使用mouseListener打开新的JFrame

我试图添加一个侦听器到我的程序，当面板被点击时它将打开一个新的JFrame。例如jpanel4是面板标签的消息。当我点击jpanel4时，我希望它打开SendMessages JFrame，它是SendMessages类。如何使用mouseListener打开新的JFrame

任何有关我需要去哪个方向的见解？这种方法是否可行？

    public static void main(String args[])

    /* Create and display the form */ 
    java.awt.EventQueue.invokeLater(new Runnable() { 
     public void run() { 
      new UserProfile().setVisible(true); 
     } 
    }); 
} 
// Variables declaration - do not modify      
private javax.swing.JLabel jLabel1;

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);

应用程序应该只有一个单一的JFrame。您应该为辅助窗口使用JDialog。 – camickr

要扩展@camickr评论..请参阅[使用多个JFrames，好/坏实践？]（http://stackoverflow.com/a/9554657/418556） –

退房How to mouse listeners，但基本上

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