JTabbedPane中的JButton

Question

我正在用JTabbedPane和JButton編寫一個交互式程序。到目前爲止，我已經能夠使它所以當「保留一個航班」選項卡中單擊，此面板顯示出來：

我想這也將採用的MouseListener時顯示圖像我點擊任一按鈕。代碼是什麼樣的？

這是我目前的方法：

顯示圖像：

protected JComponent makeImagePanel(String path) 
{ 
    try{ 
     JPanel panel = new JPanel(false); 
     BufferedImage myPicture = ImageIO.read(new File(path)); 
     JLabel picLabel = new JLabel(new ImageIcon(myPicture)); 
     panel.add(picLabel); 

     return panel; 
    }catch (IOException e) 
    { 
     throw new IllegalArgumentException("Unable to load" + path); 
    } 

} 

和鼠標事件：

 protected JComponent FlightOptions() 
    { 
    JPanel panel= new JPanel(false); 
    JButton international= new JButton("International Flights"); 
    JButton domestic= new JButton("Domestic Flights"); 
    international.setVerticalTextPosition (AbstractButton.CENTER); 
    international.setHorizontalTextPosition(AbstractButton.LEADING); 
    domestic.setVerticalTextPosition (AbstractButton.CENTER); 
    domestic.setHorizontalTextPosition(AbstractButton.LEADING); 
    international.setActionCommand("international"); 
    domestic.setActionCommand("domestic"); 
    international.setEnabled(true); 
    MouseAdapter2 mouse= new MouseAdapter2(); 
    international.addMouseListener(mouse); 
    domestic.addMouseListener(mouse); 
    panel.setLayout(new GridLayout(1, 1)); 
    panel.add(international); 
    panel.add(domestic); 
    return panel; 
} 
class MouseAdapter2 extends MouseAdapter { 

    public void mousePressed(MouseEvent e) { 
     JButton buttonpressed = (JButton)e.getSource(); 
     if(buttonpressed==international) 
     { 
      reservation= makeImagePanel("international_1.gif"); 
      overview.addTab("International Flight", reservation); 

     } 
    } 

謝謝！

你可以通過使用

jButton2.setPressedIcon(new javax.swing.ImageIcon(getClass().getResource("/newpackage/Water lilies.jpg"))); 

運行這段代碼，看看它是如何工作的
