Q_DECLARE_TYPEINFO and namespaces - how does it work?
I've used Q_DECLARE_TYPEINFO before on classes that I didn't put into any specific namespace, and never had any problems.
Now I have a class that should be in a specific namespace, something like this:
} // namespace MYNAMESPACE@
How do I declare the typeinfo of this class?
If I put the Q_DECLARE_TYPEINFO inside the namespace brackets, I get the error "error: specialization of 'template<class T> class QTypeInfo' in different namespace"
If I put the Q_DECLARE_TYPEINFO after the namespace brackets (now declaring the typeinfo for MYNAMESPACE::MyClass), I get the error "error: expected unqualified-id before 'namespace'" in my corresponding cpp file, which looks like this:
} // namespace MYNAMESPACE
How is this done correctly?

I've already check these two cases with MSVS2010 and they works fine.
Do your forget a semicolon sign before @#include <QTypeInfo>@?
I'm testing on Creator with MinGW.
#include <QTypeInfo> is the first line. Why should there be a semicolon before?
Ok, tested it on VS2010 as well.
Case 1 (inside namespace bracket) actually works on VS2010.
Case 2: I did forget the semicolon after the Q_DECLARE_TYPEINFO. This case now works on both compilers. Thanks!
