[Interest] Accessing attached properties from C++

[Oleg Shparber]

OK, I've managed to access QQmlComponentAttached:

QQmlComponentAttached *attached =
QQmlComponent::qmlAttachedProperties(item);

Still don't know how to make it work with QQuickKeyNavigationAttached. Any
ideas?

Thanks!

Best,
Oleg
