How to pass reference of the GroupDataModel object from QML to C++?

I would like to hold reference of the GroupDataModel by passing it from QML to C++.

 

The C++ side is as follow:

 

void App::setCurrentGroupModel(GroupDataModel &groupModel) {
    currentGroupModel = &groupModel;
}

 

The QML side is as follow:

 

app.setCurrentGroupModel(favoriteGroupModel);

 

I received the following error:

 

assets//main.qml:246: Error: Unknown method parameter type: GroupDataModel&

 

I'm still learning QML and C++. Just wondering what did I do wrong to receive the above error?

 

Thanks!

You should probably just get a reference to your listview with container->findChild<ListView*>("objectName") and then you always have access to the datamodel that its using
