How does QT add and display pictures in TextEdit

    QString imagePath = "C:/Users/asus/Pictures/QQ_Image/add.png"; // 图片文件路径

    // 创建 QImage 对象，从文件读取图像数据
    QImage image(imagePath);
    if (image.isNull()) {
        qDebug() << "Failed to load image from" << imagePath;
        return;
    }

    // 将图像插入到文本编辑器中
    QTextCursor cursor = ui->textEdit->textCursor();
    cursor.insertImage(image);
    ui->textEdit->setTextCursor(cursor);
