Making Boost.Signals2 More OOP‐Friendly - The Hermetic Vault 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 A C++ signal/slots library, mostly from the ground up This problem seems to speak towards a general weakness not only in the jl_signal library, but also in the signals/slots idiom and perhaps even the observer pattern at large. The general mechanic exists to obscure secondary side-effects at the source level, which is very useful, but the same obscurement can make it extremely difficult to see ...

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.
