Wouldn't it be easier just to ask a question if it...

Hi. Look at this sample : https://doc.qt.io/qt-5/qtwebengine-webenginewidgets-webui-example.html It has a Html page that load statically via qwebengingeview. I Wana add more button to this Html page and connect it to c++ functions. I noticed that I should create qwebchanbel to communicate between Javascript and c++ worlds. But before that I should create my own class that I Wana share its method with javasctip side: class JsInterface: public QObject { Q_OBJECT public: /// Log, for debugging Q_INVOKABLE void log(const QString& str) const { qDebug() << "LOG from JS: " << str; } }; And in Html page inside a script tag, I used this snippet: new QWebChannel(qt.webChannelTransport, function (channel) { // now you retrieve your object var JSobject = channel.objects.TheNameOfTheObjectUsed; }); But when I run the application, it complains that there is no qwebchannel object exists. For more information look at the first answer to this question : https://stackoverflow.com/questions/28565254/how-to-use-qt-webengine-and-qwebchannel/36601118

Wouldn't it be easier just to ask a question if it's related to C++ instead of asking about asking? 🤔
