Advice on how to implement if possible?

[SPlatten]

I want to implement a function that is invokable from JavaScript, I want to be able to call C++ functions from JavaScript, all the controls have unique ID's.

This is what I have so far:

/**
 * @brief clsScriptHelper::invoke
 * @param crstrID Constant reference to ID for node / widget to invoke
 * @param crstrMethod Constant reference to method to invoke
 * @param crlstArgs Constant reference to stringlist containing arguments
 * @return true if invoke call ok else false
 */
bool clsScriptHelper::invoke(const QString& crstrID, const QString& crstrMethod
                                  , const QStringList& crlstArgs) {
    clsXMLnode* pobjNode(clsXMLnode::spobjGetNodeById(crstrID));
    QWidget* pobjWidget;
    bool blnRC(false);
    if ( pobjNode != nullptr
    && (pobjWidget = pobjNode->pobjGetWidget()) != nullptr ) {
        QGenericArgument ga(crlstArgs[0].toLatin1().constData());
        blnRC = QMetaObject::invokeMethod(pobjWidget, crstrMethod.toLatin1(), ga);
    }
    return blnRC;
}

I'm looking for some input / help on how I could implement this? Ideally I would like to pass all the required arguments from crlstArgs.

The above has no warnings, but presently its hard coded for just a single parameter, I would like it to adapt to the number of arguments passed in the list.
