PortSettings Panel screenshot添加一個JPanel到一個ActionListener

我已經創建了一個擁有所有上，我需要（它被稱爲PortSettings）的JradioButton將一個JPanel。我也有一個叫做端口設置的按鈕，當用戶點擊按鈕時，我需要JPanel出現並顯示單選按鈕。我試圖將JPanel添加到actionlistener中，但它不起作用。我的代碼如下。我從其他按鈕中刪除了除Portsettings按鈕之外的所有其他ActionListener。如果這個問題令人困惑，我很抱歉。我很難解釋我需要做什麼。我已經上傳了面板的外觀圖以及我的程序的屏幕截圖。

     frame.setSize(1000, 1000); 
     frame.setTitle("RBA Test Application"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setVisible(true);

    PortSettings.add(ethernet); 
    PortSettings.add(rs);

    PortSettings.add(usbhid); 
    PortSettings.add(next);

    frame.pack(); 



} 

@Override 
public void actionPerformed(ActionEvent arg0) { 
    // TODO Auto-generated method stub 

} 






}

我試圖添加一個JFrame到的ActionListener然後添加的JPanel到JFrame但是當我點擊端口設置按鈕沒有任何反應。另外，當我嘗試將JPanel添加到JFrame時，它告訴我將JPanel PortSettings = new JPanel（）;放在最前面。這是代碼。

可能是我不明白的東西，但可能使這個JFrame上的按鈕與一些jPanels，使他們可見或不可見將是更好的主意。 –

你在正確的軌道上，但你不想將PortSettings面板添加到新的JFrame，但在你以前建立的面板上的某個地方，分配給本地變量frame。所以，你的動作偵聽器，而應是

portsettings.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      frame.add(PortSettings, BorderLayout.SOUTH); 
      frame.pack(); 
     } 
    });

（這是假設你真的想它在那個瞬間增加了框架，而不是從一開始就添加它無形的權利，並把它可見，像@Aleksei建議。 ）

有關final的錯誤消息是因爲您在（匿名）內部類中使用PortSettings - 即ActionListener。在我提出的修改也是如此frame，所以你必須適應它的聲明，以及：

final JFrame frame = new JFrame();

之所以具有很強的技術性和現在跑題了：就去做。

相反，如果你想要的面板出現在單獨窗口，你需要一個JDialog，沒有第二個JFrame：

portsettings.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      JDialog dialog = new JDialog(frame); 
      dialog.add(PortSettings); 
      dialog.pack(); 
      dialog.setVisible(true); 
     } 
    });

看看在JOptionPane類的豐富的選擇從對話中獲得更多功能的方法。

只是動作監聽器添加到您的所有按鈕。 是這樣的：

yourButton.addActionListener(this);

對所有按鈕都這樣做。

然後把你的TestPalication類的actionPreformed方法和做什麼：

@Override 
public void actionPerformed(ActionEvent arg0) { 
    ((JRadioButton) arg0.getSource()).setTitle("Clicked!"); 
}

你的問題問得有點混亂，但我希望這澄清了一點點。

當我點擊按鈕portsettings，我需要面板PortSettings來。我剛剛發佈了一張關於面板應該看起來像什麼樣子的圖片，當我完成鋪設時。 –
