I wrote my own light weight Signal/Slot classes which return connection handles. The existing answer’s key system is pretty fragile in the face of exceptions. You have to be exceptionally careful about deleting things with an ... C++11 Signals and Slots! - Simon Schneegans
The observer pattern. Nearly all UI toolkits have a mechanism to detect a user action, and respond to this action. Some of them use callbacks, others use listeners, but basically, all of them are inspired by the observer pattern. Observer pattern is used when an observable object wants to notify other observers objects about a state change ...

Observer Pattern on Swift with Signals – Hacker Noon The Observer Patter (sometimes also called Notifications, Broadcast-Listener, or Publish-Subscribe pattern) is a communicationI came across this awesome library while looking for alternative methods to implement an Observer Pattern. I liked this one particularly because of its simple implementation. Как использовать сигналы и слоты для шаблона… Сообщества (229) c++ design-patterns signals observer-pattern signals- slots.Мне нужно реализовать его с сигналом и слотами (например, с помощью boost :: signals2). Однако я не знаю, как должны выглядеть слоты и сигналы и как они должны быть размещены. c++ How to use signals and slots for observer pattern? -… So, in terms of signals and slots. The basics are that you connect signals to slots, which will be called each time the signal they're connected to is emitted. To go further, you could for example have a slot in the Observable, connected to a signal that an Observer will emit to tell the Observable it has to be...

Signal/Slot classes which return connection handles. The existing answer's key system is pretty fragile in the face of exceptions. You have to beSlotRegister provides a public interface which you can safely link to a private Slot. This protects against external objects calling your observer methods.
Boost.Signals2 implements the signal/slot concept. One or multiple functions – called slots – are linked with an object that can emit a signal. Every time the signal is emitted, the linked functions are called. The signal/slot concept can be useful when, for example, developing applications with graphical user interfaces. Observer Design Pattern - SourceMaking Observer design pattern. The Observer defines a one-to-many relationship so that when one object changes state, the others are notified and updated automatically. Encapsulate the core (or common or engine) components in a Subject abstraction.
When would polling for events be better than using
In my experience you should go with some hybrid Signal/Slots inside an abstract class, mainly because the Listener pattern doesn't work very well on C++ as inner classes have zero visibility over the outerI always found the Observer Pattern almost similar to the usual event-driven approach. Callback / Command vs EventListener / Observer Pattern -… I'm implementing my very own signal/slot (observer pattern, Qt style) mechanism so I can have a property that notifies ... stuff... that is has changed. I think C++11 provides everything necessary to make a very succint and featureful implementation.
