Add support for QQmlListProperty<QQmlComponent>

Currently in a class derived from QQuickItem I can declare a delegate property like that:

Q_PROPERTY(QQmlComponent delegate READ delegate ...)
Q_CLASSINFO("DefaultProperty", "delegate")

and apply a Text component in QML like that:

MyClass {
  Text {
  }
}

Now I want to add another Text component to my item class like so:

MyClass {
  Text {
  }
  Text {
  }
}

therefore I change my class to:

Q_PROPERTY(QQmlListProperty<QQmlComponent> delegates READ delegates ...)
Q_CLASSINFO("DefaultProperty", "delegates")

But now I get an runtime error saying that it's not possible to apply an object to my property. (Sorry I don't have the correct error message at hand.)

I don't need the instantiated objects in my list, I need the components to instantiate the actual objects in code.

Would it be possible to support multiple delegates that way?
