三、在线协助

一、所需工具软件

1. VS, Qt

2. Win10, Win11

二、使用步骤

1.引入库

代码如下（示例）：

#include "QUrl"
#include <iostream>
#include<string>
#include<QKeyEvent>
#include<QFontDatabase>
#include<QWebEngineSettings>
#include<QWebEngineCookieStore>

2.窗体界面

代码如下（示例）：

QT_BEGIN_NAMESPACEclass Ui_MainWindowClass
{
public:QAction *actionaa;QWidget *centralWidget;QGridLayout *gridLayout_3;QFrame *frame_2;QGridLayout *gridLayout_2;QComboBox *comboBox;QHBoxLayout *horizontalLayout;QPushButton
