    Default Send shared_ptr using signal

    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.
