[Interest] what are the requirements for QMetaType::metaObjectForType(QMetaType::type("QQuickLayout*")) to work?

QQuickLayout has a QML_NAMED_ELEMENT macro which means it's picked up by 
qmltyperegistrar which does what it says. Of course it only does that if 
you actually import QtQuick somewhere. That's probably the difference 
between the two cases.

No.
