[Qt-interest] Using typedef'ed custom type as Q_PROPERTY

[Andras Toth]

Thanks for making that clear. The problem is, however, that if the
type ID is not registered, a runtime warning is issued:

QMetaProperty::read: Unable to handle unregistered datatype 'ID' for
property 'Cat::id'

and indeed, the property setting and querying does not work for this value.

Is there a workaround for this, or can we state that it is impossible
to use typedef'ed types as properties in Qt?
