[Interest] QSharedPointer and qRegisterMetaType

[Carsten Schneemann]

Hi Igor,

if you're using the code quoted in your message then you have simply registered your pointer class with the wrong type name. If you use
qRegisterMetaType<SharedInt>("SharedInt");
then things should work.

You should also be careful with typedefs like "SharedInt" for your pointer class. Qt's meta type system is largely based on string comparison, so even if a type is just an alias of another, moc might not have taken this into account and you will get an "incompatible sender/receiver arguments" warning at runtime.

Carsten.
