public:
  Action(): QObject(0) {}
  QString name() con         


        

Answer 1

It is possible using QJSValue. For example:

//C++
Q_INVOKABLE void getData(QJSValue value) {
    if (value.isCallable()) {
        QJSValueList args;
        args << QJSValue("Hello, world!");
        value.call(args);
    }
}

//QML
action.getData(function (data){console.log(data)});
