JFrame如何检测去图像化是否完成

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

public class JFrameImageCompletionDemo {
    public static void main(String[] args) {
        JFrame frame = new JFrame("JFrame Image Completion Demo");
        frame.setSize(400, 300);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 添加组件监听器
        frame.addComponentListener(new ComponentAdapter() {
            @Override
            public void componentShown(ComponentEvent e) {
                System.out.println("JFrame is fully shown and image completion is done.");
                // 在这里执行界面完全显示后的操作
            }
        });

        frame.setVisible(true);
    }
}
