How to get Object's pointer instantiated in QML engine

[kofr]

I have

qmlRegisterType<DataModel>("one.DataModel", 1, 0, "DataModel");

qmlRegisterType<DataModel>("one.DataModel", 1, 0, "DataModel");

To copy to clipboard, switch view to plain text mode 

and I instance this in QML

DataModel {
}

DataModel {
}

To copy to clipboard, switch view to plain text mode 

I need to get pointer to the istantiated objct in C++ side. BUT I do not want to use aproach with use of

findChild()

findChild()

To copy to clipboard, switch view to plain text mode 

.

Added after 30 minutes:

I got the solution

QObject *dataModel = engine.rootObjects()[0]->property("refToMainModelForC").value<QObject*>();
    qDebug() << dataModel << "is address of data model";

QObject *dataModel = engine.rootObjects()[0]->property("refToMainModelForC").value<QObject*>();
    qDebug() << dataModel << "is address of data model";

To copy to clipboard, switch view to plain text mode 

in QML

property var refToMainModelForC: treeModel
    DataModel {
        id: treeModel
        property var viewCurrentIndex: null
    }

property var refToMainModelForC: treeModel
    DataModel {
        id: treeModel
        property var viewCurrentIndex: null
    }

Or the model could register itself inside its C++ code.
Or you call a register function in QML when you want to register a particular model.

Both obviously a lot cleaner than making the C++ code depend in a specific property name on a specific object.

And as always when "the need" to access a QML instantiated object arises: what do you need this for?
