如何检测JPanel子组件绘制事件？

import javax.swing.*;
import java.awt.*;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;

public class MyPanel extends JPanel {
    public MyPanel() {
        // 添加组件监听器
        addComponentListener(new ComponentAdapter() {
            @Override
            public void componentShown(ComponentEvent e) {
                // 子组件绘制事件处理逻辑
                System.out.println("子组件被绘制");
            }
        });
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        // 绘制子组件
        // ...
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("JPanel子组件绘制事件检测");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        MyPanel panel = new MyPanel();
        frame.add(panel);

        frame.setSize(300, 200);
        frame.setVisible(true);
    }
}
