That's one of the reasons many of the "data" classes in Qt are implicitly shared, and what's more they have internal thread-safe reference counting. On a side note one of the side effects of using signals and slots is you shouldn't need to use mutexes directly. The signal slot connection (with a few rare exceptions) is safe across thread ...

Signals and slots is a language construct introduced in Qt for communication between objects ... on the FunctionalInterface annotation introduced in Java 8. C ++: vdk-signals - thread-safe, type-safe, written in C++11 with atomic variables.
Qt documentation states that signals and slots can be direct, queued and auto. It also stated that if object that owns slot 'lives' in a thread different from object that owns signal, emitting such signal will be like posting message - signal emit will return instantly and slot method will be called in target...

Helloworld922's Blog: Thread-Safe Signals/Slots using C++11 Introduction. For any C++ developer who's used Qt, we've grown to love the Signals/Slots idiom it presents for creating clean Observer code. However, it relied on the Qt Moc pre-compiler tool, which meant any project that wanted to use this feature had to use follow along with the Qt idiom, which really made Qt applications look potentially foreign despite being written in C++.
Peer reviewing is an important step, and there is a reason why we do it in Qt. Code in libraries (such as Qt) requires much greater care than application code. The main reason is that you need to maintain compatibility for your users.
