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 thread’s event loop.

The signals and slots mechanism is fundamental to Qt programming. It enables the application programmer to bind objects together without the objects knowing anything about each other. We have already connected some signals and slots together, declared our own signals and slots, implemented our own ... Qt e C++: signal e slot « Portale Programmazione Gli oggetti Qt comunicano tra loro mediante un flessibile meccanismo composto da signal e slot. Un signal è un metodo che viene emesso, mediante la parola chiave emit, quando si ritiene opportuno. Essi non vengono implementati ma solo dichiarati e vanno inseriti, all’interno della classe, nella sezione signals. Implementing my own signal slot mechanism using C++11 I programmed in C# and I used the Qt framework. Both of them have their own signal slot mechanism which are really powerful. I looked at several implementations in C++ and based on what I learnt from QThread - Qt Developer Days Cross Thread Signals/Slots Cross thread signals are really events The receiver needs a running event loop The sender does NOT need an event loop Signals are placed in the event queue All threads can emit signals regardless of pattern Only threads with running event loops should have in-thread slots

C ++ Thread / Slot Cross Security Signals - codesd.com It seem that the only implementation that provide Safe Cross-Thread Signals for both the Signal class and what's being called in the slot is QT.But I cannot use QT in the project I'm doing. So how could I provide safe Slots call from a different thread (Using Boost::signals2 for example)? Problem with QT / Threads / Signals / Slots - C / C++ The Signals and Slots mechanism is synchronous: when a signal is emitted, all slots are called immediately. The slots are executed in the threadQt, threading, Slots, and related things are not defined by the C++ language. They happen to be, therefore, outside the scope of this newsgroup.
