The same pattern with probable little modifications is known as Listener, Signal/Slot, Event Handling, etc. The idea is that one object somehow lets another object or objects know about some change (mouse click, text edited, some member data updated, a row deleted from the table in ...

The observer 1 design pattern is by far the most popular and widely known among behavioural patterns 2. Unfortunately, unlike other mainstream languages out there, the C++ standard library doesn’t provide out of the box observer implementation. Luckily, Boost contains Signals2, a signal/slot 3 library
Observer pattern Wikipedia Boost Signals Qt. There has been a great deal of discussion in the D newsgroups over this, and several implementations: signal slots library Signals and Slots in D Dynamic binding -- Qt's Signals and Slots vs Objective-C Dissecting the SS about harmonia Another event handling module Suggestion: signal/slot mechanism Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. Qt for Beginners - Qt Wiki 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 ...
