如何設置JTextField的標籤？

Question

如何修復Gateway的標籤，這是唯一沒有顯示的標籤。其餘的都在展示。

public TextLabelMirror() { 

    // DHCP 
    String[] petStrings = { "Static", "Auto" }; 
    JPanel namePanel = new JPanel(new BorderLayout()); 
    JLabel nameLabel = new JLabel("DHCP Mode: "); 
    nameLabel.setDisplayedMnemonic(KeyEvent.VK_N); 
    final JComboBox nameTextField = new JComboBox(petStrings);  
    nameLabel.setLabelFor(nameTextField); 
    namePanel.add(nameLabel, BorderLayout.WEST); 
    namePanel.add(nameTextField, BorderLayout.CENTER); 

    // IP - Address 
    JPanel namePanel0 = new JPanel(new BorderLayout()); 
    JLabel nameLabel0 = new JLabel("IP: "); 
    nameLabel0.setDisplayedMnemonic(KeyEvent.VK_N); 
    final JTextField nameTextField0 = new JTextField(20);   
    nameLabel0.setLabelFor(nameTextField0); 
    namePanel0.add(nameLabel0, BorderLayout.WEST); 
    namePanel0.add(nameTextField0, BorderLayout.CENTER); 


    // NetMask 
    JPanel namePanel1 = new JPanel(new BorderLayout()); 
    JLabel nameLabel1 = new JLabel("Netmask: "); 
    nameLabel1.setDisplayedMnemonic(KeyEvent.VK_N); 
    final JTextField nameTextField1 = new JTextField(20);  
    nameLabel1.setLabelFor(nameTextField1); 
    namePanel1.add(nameLabel1, BorderLayout.WEST); 
    namePanel1.add(nameTextField1, BorderLayout.CENTER); 

    // Gateway 
    JPanel namePanel2 = new JPanel(new BorderLayout()); 
    JLabel nameLabel2 = new JLabel("Gateway: "); 
    nameLabel2.setDisplayedMnemonic(KeyEvent.VK_N); 
    final JTextField nameTextField2 = new JTextField(20);  
    nameLabel2.setLabelFor(nameTextField2); 
    namePanel2.add(nameLabel2, BorderLayout.WEST); 
    namePanel2.add(nameTextField2, BorderLayout.WEST); 

    // Save now 
    JPanel namePanel3 = new JPanel(new BorderLayout()); 
    final JButton nameTextField3 = new JButton("Save");  
    namePanel3.add(nameTextField3, BorderLayout.CENTER); 
    .... 

    } 

Answer 1

您似乎已將它們都添加到WEST。我假設你打算將nameTextField2添加到CENTER或其他東西。

namePanel2.add(nameLabel2, BorderLayout.WEST); 
namePanel2.add(nameTextField2, BorderLayout.WEST); 

像這樣：

namePanel2.add(nameLabel2, BorderLayout.WEST); 
namePanel2.add(nameTextField2, BorderLayout.CENTER);
