Accessing properties of 2D QML object in a 3DView via C++

srce

How can I access the properties of a 2D object that is in a 3D view?

example.qml:

View3D {
    Node {        
        objectName: "myNodeObj",
        x: 10
        Text {
            objectName: "myTextObj",
            text: "Some text"
      }
}

I can access the properties of Node with:

QObject *n = ui.quickWidget->rootObject()->findChild<QObject*>("myNodeObj");
n->setProperty("x", 3);

However, this doesn't work for 2D objects such as Text:

QObject *t = ui.quickWidget->rootObject()->findChild<QObject*>("myTextObj");

Returns nullptr, so I can't change the text.

If I print out the children of Node, then rather than finding a Text object, it's been replaced with an unnamed private QQuick3DItem2D. https://doc.qt.io/qt-6/qtquick3d-architecture.html says that 2D items get wrapped in QQuick3DItem2Ds. How can they be accessed?

Thanks.
