重新加載組件框架

Question

我正在處理時間表預訂應用程序，當我運行它顯示組件（總框架）的項目時，但是我希望當按鈕重新加載時，組件應該被吐出。一個低於其他溢出）???

根據您的描述，我認爲您需要在點擊一個按鈕的同時在框架中添加splitpane，或者您已經在框架中有一個splitpane，並希望在點擊按鈕時添加面板。

因爲你可以做這樣的事情第一個選項：

final JFrame frame = new JFrame("Split test"); 
    frame.setSize(400, 400); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    final JPanel jPanel2 = new JPanel(); 
    JLabel jLabel = new JLabel("I am added by click on button"); 
    jPanel2.add(jLabel); 

    final JPanel jPanel = new JPanel(); 
    JButton button = new JButton("Click me to add pane in split"); 
    jPanel.add(button); 

    button.addActionListener(new ActionListener() { 
     @Override 
     public void actionPerformed(ActionEvent arg0) { 
      JSplitPane pane = new JSplitPane(JSplitPane.VERTICAL_SPLIT); 
      pane.add(jPanel); 
      pane.add(jPanel2); 
      pane.setDividerLocation(frame.getHeight()/2); // set Divider location. 
      frame.remove(jPanel); 
      frame.add(pane); 
      frame.validate(); 
     } 
    }); 

    frame.add(jPanel); 
    frame.setVisible(true); 

如果你被困在一個稍後再嘗試這個辦法：

final JFrame frame = new JFrame("Split test"); 
    frame.setSize(400, 400); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    final JSplitPane pane = new JSplitPane(JSplitPane.VERTICAL_SPLIT); 
    frame.add(pane); 

    pane.setEnabled(false); // stop user from clicking on divider of split pane. 

    final JPanel jPanel2 = new JPanel(); 
    JLabel jLabel = new JLabel("I am added by click on button"); 
    jPanel2.add(jLabel); 

    final JPanel jPanel = new JPanel(); 
    JButton button = new JButton("Click me to add pane in split"); 
    jPanel.add(button); 
    pane.add(jPanel); 

    button.addActionListener(new ActionListener() { 
     @Override 
     public void actionPerformed(ActionEvent arg0) { 
      pane.add(jPanel2); 
      pane.setDividerLocation(frame.getHeight()/2); // set Divider location. 
      pane.setEnabled(true); // let user change divider location. 
     } 
    }); 

    frame.setVisible(true);
