如何拥有一个透明的JTextField？

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

public class TransparentTextFieldExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Transparent JTextField Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(300, 200);
        
        JPanel panel = new JPanel();
        panel.setLayout(new FlowLayout());
        
        JTextField textField = new JTextField();
        textField.setOpaque(false);
        textField.setBorder(null);
        textField.setFont(new Font("Arial", Font.PLAIN, 12));
        textField.setForeground(Color.WHITE);
        
        panel.add(textField);
        frame.add(panel);
        frame.setVisible(true);
    }
}
