Send shared_ptr using signal

[theZivkovic]

I have a thread which makes a huge object
and I want to pass it using qt signal back to main thread.

Can I pass the shared_ptr (c++11) reffering to that object,
and how?

You need to declare the specialized shared pointer type with Q_DECLARE_METATYPE and call qRegisterMetaType() somewhen before using the signal.
