需要解决以下几个问题
政府项目新浏览器兼容老系统ActiveX控件Qt WebEngineView没有直接的实现方案需要利用Qt的ActiveX兼容模块与浏览器往返多次交互Qt ActiveX未实现COM事件通知官方Win32示例存在滥用lambda函数的嫌疑lambda函数多层嵌套程序逻辑层次混乱整个逻辑被揉成一垛。
官方示例代码
官方介绍文档在这里https://learn.microsoft.com/microsoft-edge/webview2/get-started/win32。官方代码仓库在这里GitHub - MicrosoftEdge/WebView2Samples: Microsoft Edge WebView2 samples
摘录一段lambda多层嵌套的代码你们体会一下 CreateCoreWebView2EnvironmentWithOptions(nullptr, nullptr, nullptr,CallbackICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler([hWnd](HRESULT result, ICoreWebView2Environment* env) - HRESULT {// Create a CoreWebView2Controller and get the associated CoreWebView2 whose parent is the main window hWndenv-CreateCoreWebView2Controller(hWnd, CallbackICoreWebView2CreateCoreWebView2ControllerCompletedHandler([hWnd](HRESULT result, ICoreWebView2Controller* controller) - HRESULT {if (controller ! nullptr) {webviewController controller;webviewController-get_CoreWebView2(webview);}// Add a few settings for the webview// The demo step is redundant since the values are the default settingswil::com_ptrICoreWebView2Settings settings;webview-get_Settings(settings);settings-put_IsScriptEnabled(TRUE);settings-put_AreDefaultScriptDialogsEnabled(TRUE);settings-put_IsWebMessageEnabled(TRUE);// Resize WebView to fit the bounds of the parent windowRECT bounds;GetClientRect(hWnd, bounds);webviewController-put_Bounds(bounds);// Schedule an async task to navigate to Bingwebview-Navigate(Lhttps://www.bing.com/);// NavigationEvents// Step 4 - Navigation events// register an ICoreWebView2NavigationStartingEventHandler to cancel any non-https navigationEventRegistrationToken token;webview-add_NavigationStarting(CallbackICoreWebView2NavigationStartingEventHandler([](ICoreWebView2* webview, ICoreWebView2NavigationStartingEventArgs* args) - HRESULT {wil::unique_cotaskmem_string uri;args-get_Uri(uri);std::wstring source(uri.get());if (source.substr(0, 5) !

解决方案
下面以实现自动登录外网网关为目标企业微信自动上线免开机输入账号密码。这样领导看到你上线可以开机以后就可以慢慢吃早餐了。开个玩笑
本实现方案把官方示例代码做成了静态库没有添加其它东西。
新建CMake项目
这里用到了Qt5静态库目的是单文件可执行不需要部署。需要静态库的读者可以自行删除。代码如下

用Qt Designer设计一个简单的窗口类型
类型名字很简单就是MainWindow。这个窗口仅启用了布局没有添加任何控件。UI代码如下
