Essential classes signal Signals and slots - Wikipedia Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code.The concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as slots. This is similar to C/C++ function pointers, but ...

Simple thread-safe signal/slot C++14 library, which is templated and include-only. No linking required. Just include the header file "sigs.h".

@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 ... Is it safe to emit a signal on an object from another thread (if the slot is connected as QueuedConnection)?I couldn't find a specific piece of documentation that would mention this, the most relevant quote I found is this:. QObject is reentrant. Threadsafe C++ signals done right : cpp - reddit.com Indeed. Qt signal/slot are specifically designed to make threads easy. You just write the code with signals and then, depending on the thread where the objects are created at the beginning (or to which thread they are moved), same signals act as direct calls or as message queues.

C++ signals and slots. vdk-signals is a type-safe and thread-safe signals-slots system for standard C++ designed with performance and simplicity in mind. It follows the main philosophy of the C++ language avoiding unnecessary overheads and superfluous functionality that can slow down your program.

Chapter 67. Boost.Signals2 - Multithreading Almost all classes provided by Boost.Signals2 are thread safe and can be used in multithreaded applications. For example, objects of type boost::signals2::signal and boost::signals2::connection can be accessed from different threads. On the other hand, boost::signals2::shared_connection_block is not thread safe. Messaging and Signaling in C++ - Meeting C++
