Signal slot vs observer pattern

Signal and Slots. Signals and slots is a language construct introduced in Qt, which makes it easy to implement the Observer pattern while avoiding boilerplate code. The concept is that controls (also known as widgets) can send signals containing event information which can be received by other controls using special functions known as slots.

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.
