Type-safe Signals and Slots in C++: Part 2 - CodeProject Boost and QT also offer signal / slot functionality (see Part 1 of the article series). However, the signal slot system by ElmueSoft described in this article has the great advantage that it is tiny, does not need any big libraries or compiler plugins and it is free! You will not want to miss it if you once got used to it! P.S. Thread-Safety - 1.43.0 - boost.org It is expected that slot objects will be created then connected to a signal in a single thread. Once they have been copied into a signal's slot list, they are protected by the mutex associated with each signal-slot connection. The signals2::trackable class does NOT provide thread-safe automatic connection management. In particular, it leaves ...

@ddriver: It is really very very simple, he has two threads: main and worker, main emits a signal and so a slot gets called that deletes things and the worker thread signals back to the main thread when e.g. done, and that operates on the GUI items, too. He asks whether this is safe. – lpapp Dec 6 '14 at 10:32 | c++ - Is it safe to emit signal from another thread The queue is guaranteed to be thread safe so it is absolutely safe to emit signals across threads. The quote in your questions talks about the situation where you make a direct call on the object living in T1 from T2. There is a great article about threads, qobjects, signals, slots and how everything relates to each other: Threads Events c++ - how in BOOST send a signal in a thread and have the

Example 67.17 creates two threads that execute the loop() function, which accesses s one hundred times to call the associated lambda function. Boost.Signals2 explicitly supports simultaneous access from different threads to objects of type boost::signals2::signal.. Example 67.17 displays numbers from 0 to 99. Because i is incremented in two threads and written to the standard output stream in ...

Signals are connected to some set of slots, which are callback receivers (also called event targets or subscribers), which are called when the signal is "emitted." Signals and slots are managed, in that signals and slots (or, more properly, objects that occur as part of the slots) can track connections and are capable of automatically ...
