Introduce QMetaType::UnknownType.
QMetaType::Void was ambiguous, it was pointing to a valid type (void) and in the same time it was signaling errors in QMetaType. There was no clean way to check if returned type was valid void or some unregistered type. This feature will be used by new QMetaObject revision which will store type ids instead of type names. So it will be easy to distinguish between: void mySlot(); MyUnregisteredType mySlot(); Change-Id: I73ff097f75585a95e12df74d50c6f3141153e771 Reviewed-by: Kent Hansen <> Reviewed-by: Olivier Goffart <>
