在JPanel上填充JTextFields

通過下面的代碼，我使用JTextFields和JLabels創建JPanel並將該面板添加到另一個JPanel。如何調整infoPanel上的JTextField之間的間距？在JPanel上填充JTextFields

我試過GridBagLayout和GridLayout有不同的和不希望的結果。現在的方式至少讓它們垂直對齊，但我似乎無法在它們上方和下方添加空間。這個問題上的任何大師能夠幫忙嗎？

public DrawPanelMain() { 
    JPanel btnPanel = new JPanel(); //Creates a new Panel for the buttons 
    JPanel infoPanel = new JPanel(); 
    JPanel fields = new JPanel(); 

    //Text boxes for infoPanel 
    JTextField textField1 = new JTextField(20); 
    JTextField textField2 = new JTextField(20); 
    JTextField textField3 = new JTextField(20); 
    JTextField textField4 = new JTextField(20); 
    JTextField textField5 = new JTextField(20); 
    JTextField textField6 = new JTextField(20); 

    //JLabels for infoPanel 
    JLabel jLabel1 = new JLabel("Serial Number: "); 
    JLabel jLabel2 = new JLabel("Information: "); 
    JLabel jLabel3 = new JLabel("Information: "); 
    JLabel jLabel4 = new JLabel("Information: "); 
    JLabel jLabel5 = new JLabel("Information: "); 
    JLabel jLabel6 = new JLabel("Information: "); 

    //These are the buttons that will be added to the btnPanel 
    btnPanel.add(new JButton(new AddSwitchAction("Add Switch Panel"))); 
    btnPanel.add(new JButton(new PushConfigAction("Push Config"))); 
    btnPanel.add(new JButton(new ActivateAllAction("Activate All"))); 
    btnPanel.add(new JButton(new DeactivateAllAction("Deactivate All"))); 

    //Fields that will be added to infoPanel 
    fields.add(jLabel1); 
    fields.add(textField1); 
    fields.add(jLabel2); 
    fields.add(textField2); 
    fields.add(jLabel3); 
    fields.add(textField3); 
    fields.add(jLabel4); 
    fields.add(textField4); 
    fields.add(jLabel5); 
    fields.add(textField5); 
    fields.add(jLabel6); 
    fields.add(textField6); 

    //Sets border padding for the infoPanel 
    fields.setBorder(new EmptyBorder(20, 20, 0, 20)); 

    //Draws border for the infoPanel 
    infoPanel.setBorder(BorderFactory.createRaisedBevelBorder()); 

    //Sets layout for the fields panel 
    fields.setLayout(new GridLayout(6, 1)); 

    //Add fields to infoPanel 
    infoPanel.add(fields); 

    //Add panels to tabbedPane 
    setLayout(new BorderLayout()); 
    add(tabbedPane, BorderLayout.CENTER); 
    add(btnPanel, BorderLayout.PAGE_END); 
    add(infoPanel, BorderLayout.EAST); 

}

請看看這篇文章，關於[在Swing GUI的提供空格]（HTTP：// stackoverflow.com/q/17874717/1057230）。希望它對這個主題有一些幫助:-)簡而言之，對每個'Layout'關注使用重載的構造函數。 –

@ncEcOw你da man，這正是我一直在尋找的！ – feltersnach

創建一個組合邊框

field.setBorder(BorderFactory.createCompoundBorder(
     field.getBorder(), 
     BorderFactory.createEmptyBorder(int top, int left, int bottom, int right)));

或者放一些插圖

field.setMargin(new java.awt.Insets(int top, int left, int bottom, int right));
