A C++ signal/slots library, mostly from the ground up Calling Disconnect() on a signal while the same signal is still processing an Emit() certainly sounds like trouble. The current implementation of jl_signal does not handle this well at all: as soon as a slot is disconnected, the internal delegate node is freed and the iterator is left with a dangling pointer. What is a C++ library that you've regretted using ... - reddit But all in all, JUCE’s performance couldn’t be taken seriously. Measurement in CPU usage rather than framerates was equally horrid. With OpenGL, Qt would use 6% CPU for awesome vector stuff, effectively making my GPU do all the work, whereas JUCE doing the same thing would peg my core to 95%. Threadsafe C++ signals done right : cpp - reddit.com It may be stored inside the signal like in wigwag and boost, or inside the base class like in Qt and, probably, GObject. So, if noone connected to a signal, you still have that overhead of an empty handlers list with any approach. Regarding sharing a single mutex between signals, bo_on_software is right: it is quite easy to do that in wigwag. Signals and slots - Wikipedia
QObject::disconnect(sender, signal, reciever, method) disconnects all connections, not just the first one. The attached example should print "myslot" three times, instead of just twice. Some way to just disconnectOne() is essential for qml.

Boost.Signals The Boost.Signals library is an implementation of a managed signals and slots system.Signals and slots are managed, in that signals and slots (or, more properly, objects that occur as part of the slots) track all connections and are capable of automatically disconnecting signal/slot connections... Signal and Slots - kjellkod | Boost.Signals Signal and slots is a concept developed from Qt.

and are capable of automatically disconnecting signal/slot connections when either is destro yed. This enables the user to mak e signal/slot connections without expending a great effort to manage the lifetimes of those connections with re gard to the lifetimes of all objects involved. boost::signals2 - C++ Forum The focus of the signal/slot mechanism is the connection. When a signal dies everything is ok since the slot is not called anymore. When a slot dies we have a problem since if it is called it's likely that the program crashes, therefore a slot (using the result of connect(...)) can disconnect itself.
Disconnect specific slot from all signals | Qt Forum Is there any disconnect function that can be used to disconnect everything connected to a specific slot?but this connects only the signals in the current object. I want to disconnect ALL signals, without knowing the objects that are connected to the slot. c++ Программирование: Библиотека boost::signals2 изнутри Если перевести кратко: библиотека signals2 является реализацией инфраструктурыСигнал, принимающий 1 целочисленный аргумент и возвращающий void boost:: signals2::signal
