How to get Object's pointer instantiated in QML engine

I have

Code:

---

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

---

and I instance this in QML

Code:

---

DataModel {
}

---

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

Code:

---

findChild()

---

.

Added after 30 minutes:

I got the solution

Code:

---

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

---

in QML

Code:

---

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?
