不能 Java GUI 看起来像我想要的那样...？

Question

问题只是希望 GUI 看起来像这样：

这是我的代码

import javax.swing.JOptionPane;

class Customer
  {

    String n = JOptionPane.showInputDialog("Enter name");
    String id = JOptionPane.showInputDialog("Enter id");
    String sub = JOptionPane.showInputDialog("Enter Submit");

JOptionPane.showMessageDialog(null, null, null, JOptionPane.PLAIN_MESSAGE)

  }

}

我希望一切看起来都是水平的

Enter Name         [box to fill in name]

Enter id            [box to fill in id]

Submit              [box to enter submit]

Answer 1

您总共显示了 4 个选项面板。如果您希望所有内容都在一个选项窗格中，这可能会有所帮助：

JPanel msgPanel = new JPanel();
msgPanel.setLayout(new GridLayout(3 , 2));

msgPanel.add(new JLabel("Enter name");

JTextField nameField = new JTextField();
msgPanel.add(nameField);

//create other fields and labels

JOptionPane.showMessageDialog(null , msgPanel , "" , JOptionPane.PLAIN_MESSAGE);

String name = nameField.getText();
//read other fields

不能 Java GUI 看起来像我想要的那样...？
