Question

我使用GridLayout mananger创建我的gui，但我不喜欢额外的空间让我的按钮看起来很小。 My GUI

我希望它看起来更像这个。 Good GUI

我尝试将前两行放在另一个gridlayout中并将它们放在流布局中，但它没有用。它们最终会并排，除非窗口变得非常小，因为它应该是一个流程布局。任何想法？

标准服务小组构造函数

public StandardServices()
{
    // Create GridLayout manager with 5 rows and 1 column
    setLayout(new GridLayout(5,1));

    // Create the check boxes.
    iHardDrive = new JCheckBox("Install Hard Drive ($25.00)");
    ram = new JCheckBox("Install Ram ($15.00)");
    virus = new JCheckBox("Remove Virus ($50.00)");
    fHardDrive = new JCheckBox("Format Hard Drive ($80.00)");
    labourQuote = new JCheckBox("Hourly Labour Qoute ($10.00)");

    //Add a border around the panel.
    setBorder(BorderFactory.createTitledBorder("Standard Services"));

    // Add the checkboxes to the panel.
    add(iHardDrive);
    add(ram);
    add(virus);
    add(fHardDrive);
    add(labourQuote);
}

每小时服务面板构造函数

public HourlyService()       
{
    // Created grid layout with 2 rows, 1 column
    setLayout(new GridLayout(2,1));

    // Create labels to display instructions.
    cost = new JLabel("Parts Cost:");
    labour = new JLabel("Hours of Labour:");

    // Create two text fields 10 characters wide.
    costTextField = new JTextField(10);
    labourTextField = new JTextField(10);

    // Place a 0 in the text fields.
    costTextField.setText("0");
    labourTextField.setText("0");

    // Add a border around the layout
    setBorder(BorderFactory.createTitledBorder("Hourly Service"));

    // Add labels and text fields to the panel.
    add(cost);
    add(costTextField);
    add(labour);
    add(labourTextField);

}

LU Store GUI构造函数

public MyStoreGui()
{
    //Display a title
    setTitle("LU Computer Store");

    //Specify a default action for the close button
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    // Set the size of the window
    setSize(WINDOW_WIDTH, WINDOW_HEIGHT);

    // Create a GridLayout manager
    setLayout(new GridLayout(3,1));
    //setLayout(new FlowLayout());
    // create custom panels
    standard =  new StandardServices();
    hourly = new HourlyService();

    //Create the button panel
    buildButtonPanel();


    add(standard);
    add(hourly);
    add(buttonPanel);

    // Display the window
    setVisible(true);
}

使用GridLayout代替使用基于最大组件为所有组件提供相等间距的GridBagLayout，而不仅仅为import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import java.awt.GridLayout; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JCheckBox; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; import javax.swing.SwingUtilities; public class Test { public static void main(String[] args) { new Test(); } public Test() { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { JFrame frame = new JFrame(); frame.add(new MyStoreGui()); frame.pack(); frame.setVisible(true); } }); } public final class MyStoreGui extends JPanel { public MyStoreGui() { setLayout(new GridBagLayout()); //setLayout(new FlowLayout()); // create custom panels StandardServices standard = new StandardServices(); HourlyService hourly = new HourlyService(); GridBagConstraints gbc = new GridBagConstraints(); gbc.gridwidth = GridBagConstraints.REMAINDER; gbc.fill = GridBagConstraints.HORIZONTAL; //Create the button panel JPanel buttonPanel = buildButtonPanel(); add(standard, gbc); add(hourly, gbc); add(buttonPanel, gbc); // Display the window setVisible(true); } protected JPanel buildButtonPanel() { JPanel panel = new JPanel(); panel.add(new JButton("Calclate Changes")); panel.add(new JButton("Exit")); return panel; } } public class StandardServices extends JPanel { public StandardServices() { // Create GridLayout manager with 5 rows and 1 column setLayout(new GridLayout(5, 1)); // Create the check boxes. JCheckBox iHardDrive = new JCheckBox("Install Hard Drive ($25.00)"); JCheckBox ram = new JCheckBox("Install Ram ($15.00)"); JCheckBox virus = new JCheckBox("Remove Virus ($50.00)"); JCheckBox fHardDrive = new JCheckBox("Format Hard Drive ($80.00)"); JCheckBox labourQuote = new JCheckBox("Hourly Labour Qoute ($10.00)"); //Add a border around the panel. setBorder(BorderFactory.createTitledBorder("Standard Services")); // Add the checkboxes to the panel. add(iHardDrive); add(ram); add(virus); add(fHardDrive); add(labourQuote); } } public class HourlyService extends JPanel { public HourlyService() { // Created grid layout with 2 rows, 1 column setLayout(new GridLayout(2, 1)); // Create labels to display instructions. JLabel cost = new JLabel("Parts Cost:"); JLabel labour = new JLabel("Hours of Labour:"); // Create two text fields 10 characters wide. JTextField costTextField = new JTextField(10); JTextField labourTextField = new JTextField(10); // Place a 0 in the text fields. costTextField.setText("0"); labourTextField.setText("0"); // Add a border around the layout setBorder(BorderFactory.createTitledBorder("Hourly Service")); // Add labels and text fields to the panel. add(cost); add(costTextField); add(labour); add(labourTextField); } } }提供更多控制权，而且会尊重首选各个组件的大小
