如何创建涵盖Windows标题栏的Java Swing应用程序？

import javax.swing.*;

public class SwingApp {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JFrame frame = new JFrame("My Swing App");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setSize(400, 300);
                frame.setVisible(true);
            }
        });
    }
}

import javax.swing.*;
import java.awt.*;

public class SwingApp {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JFrame frame = new JFrame("My Swing App");
                frame.setUndecorated(true); // 移除默认的窗口装饰
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setSize(400, 300);
                frame.setVisible(true);

                // 添加自定义标题栏
                JPanel titleBar = new JPanel(new BorderLayout());
                JLabel titleLabel = new JLabel("My Swing App", SwingConstants.CENTER);
                titleBar.add(titleLabel, BorderLayout.CENTER);
                JButton closeButton = new JButton("X");
                closeButton.addActionListener(e -> System.exit(0));
                titleBar.add(closeButton, BorderLayout.EAST);
                frame.setLayout(new BorderLayout());
                frame.add(titleBar, BorderLayout.NORTH);
            }
        });
    }
}
