java创建JOptionPane及其具有固定宽度和高度的对象

Question

我正在尝试创建一个类似这样的JOptionPane。我尝试了许多布局管理器，但是（GridBagLayout，GridLayout，AbsoluteLayout）我还没有成功

例如，如果我使用GridBagLayout，ipadx确实很有用，但是JTextFields宽度取决于它们的文本长度

如果使用GridLayout，则每个对象的宽度都属于列宽

如果我使用AbsoluteLayout，则JOptionPane不会将自身扩展到带有对象的配置的JPanel边界

我需要固定的对象宽度、高度和JOptionPane当我们使用带有项目的JPanel创建它时，它应该扩展自身

哪个布局管理器最适合此任务？如果你建议的话，我会集中精力的

网格布局示例

JPanel panel = new JPanel( new GridLayout(8, 2) );

JLabel inforForNameLabel = new JLabel();
inforForNameLabel.setText("Long Label Name....................................");

final JTextField userNameTextField = new JTextField();
userNameTextField.setText("aaaaaaaaaaaaa");
userNameTextField.setEditable(false);

JLabel inforForNameSurname = new JLabel();
inforForNameSurname.setText("Long Label Name..................................");

final JTextField NameSurnameTextField = new JTextField();
NameSurnameTextField.setText("aaaaaaaaaaaa aaaaaaaaaa");

JLabel inforForStatsCombobox = new JLabel();
inforForStatsCombobox.setText("Long Label Name.................................");

JComboBox statComboBox = new JComboBox();
DefaultComboBoxModel dt = new DefaultComboBoxModel();
statComboBox.setModel(dt);
dt.addElement("USER.....");
dt.addElement("ADMIN");
statComboBox.setSelectedItem("USER.....");

JLabel inforForAuthCombobox = new JLabel();
inforForAuthCombobox.setText("Long Label Name.................................");

String[] authComboBoxObjects = { "READ", "READ/WRITE"};
final JComboBox authComboBox = new JComboBox(authComboBoxObjects);
authComboBox.setSelectedItem("READ/WRITE");

panel.add(inforForNameLabel);
panel.add(userNameTextField);
panel.add(inforForNameSurname);
panel.add(NameSurnameTextField);
panel.add(inforForStatsCombobox);
panel.add(statComboBox);
panel.add(inforForAuthCombobox);
panel.add(authComboBox);

String[] buttons = { "EXIT", "OK" };
int rc = JOptionPane.showOptionDialog(null, panel,"User Config", JOptionPane.INFORMATION_MESSAGE,JOptionPane.QUESTION_MESSAGE, null, buttons, buttons[1]);

if(rc == 0 || rc == -1){
     System.out.println(userNameTextField.getText());
}
else{
     System.out.println("Cancel...");
}

下面的代码构建选项窗格，在问题处选择所需的格式

    JPanel panel = new JPanel();
    panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));

    JLabel inforForNameLabel = new JLabel();
    inforForNameLabel.setText("Long Label Name.............................");
    inforForNameLabel.setAlignmentX(LEFT_ALIGNMENT);

    JLabel inforForNameLabel2 = new JLabel();
    inforForNameLabel2.setText("Long Label Name............................");
    inforForNameLabel2.setAlignmentX(LEFT_ALIGNMENT);

    final JTextField userNameTextField = new JTextField();
    userNameTextField.setText("aaaaaaaaaaaaa");
    userNameTextField.setEditable(false);
    userNameTextField.setPreferredSize(new Dimension(345, 30));
    userNameTextField.setMaximumSize(new Dimension(345, 30));
    userNameTextField.setAlignmentX(LEFT_ALIGNMENT);

    JLabel inforForNameSurname = new JLabel();
    inforForNameSurname.setText("Long Label Nameeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee");
    inforForNameSurname.setAlignmentX(LEFT_ALIGNMENT);

    final JTextField NameSurnameTextField = new JTextField();
    NameSurnameTextField.setText("aaaaaaaaaaaa aaaaaaaaaa");
    NameSurnameTextField.setPreferredSize(new Dimension(345, 30));
    NameSurnameTextField.setMaximumSize(new Dimension(345, 30));
    NameSurnameTextField.setAlignmentX(LEFT_ALIGNMENT);

    JLabel inforForStatsCombobox = new JLabel();
    inforForStatsCombobox.setText("Long Label Name....................");
    inforForStatsCombobox.setAlignmentX(LEFT_ALIGNMENT);

    JComboBox statComboBox = new JComboBox();
    DefaultComboBoxModel dt = new DefaultComboBoxModel();
    statComboBox.setModel(dt);
    dt.addElement("USER.....");
    dt.addElement("ADMIN");
    statComboBox.setSelectedItem("USER.....");
    statComboBox.setPreferredSize(new Dimension(200, 30));
    statComboBox.setMaximumSize(new Dimension(200, 30));
    statComboBox.setAlignmentX(LEFT_ALIGNMENT);

    JLabel inforForAuthCombobox = new JLabel();
    inforForAuthCombobox.setText("Long Label Name................................");
    inforForAuthCombobox.setAlignmentX(LEFT_ALIGNMENT);

    String[] authComboBoxObjects = { "READ", "READ/WRITE"};
    final JComboBox authComboBox = new JComboBox(authComboBoxObjects);
    authComboBox.setSelectedItem("READ/WRITE");
    authComboBox.setPreferredSize(new Dimension(200, 30));
    authComboBox.setMaximumSize(new Dimension(200, 30));
    authComboBox.setAlignmentX(LEFT_ALIGNMENT);


    panel.add(inforForNameLabel);
    panel.add(inforForNameLabel2);
    panel.add(userNameTextField);
    panel.add(inforForNameSurname);
    panel.add(NameSurnameTextField);
    panel.add(inforForStatsCombobox);
    panel.add(statComboBox);
    panel.add(inforForAuthCombobox);
    panel.add(authComboBox);

    String[] buttons = { "EXIT", "OK" };
    int rc = JOptionPane.showOptionDialog(null, panel,"User Config", JOptionPane.INFORMATION_MESSAGE,JOptionPane.QUESTION_MESSAGE, null, buttons, buttons[1]);

    if(rc == 0 || rc == -1){
        System.out.println("Cancel...");
    }
    else{
        System.out.println(userNameTextField.getText());
    }

同意JDialog可以让你完全控制

i need to know how can i make same thing via JOptionPane

UIManager似乎控制着最小尺寸。在显示选项窗格之前，您可以使用以下命令覆盖：

Dimension size = UIManager.getDimension("OptionPane.minimumSize");
size.width = 100;
UIManager.put("OptionPane.minimumSize", size);

您可以在UIManager Defaults中查看由UIManager控制的其他属性的列表。请注意，并非所有LAF都能管理相同的物业
