Jan 18, 2015 · If you've ever used Qt to build a GUI, you're probably familiar with their signal/slots implementation. For me, it was my first encounter with the idiom and I really liked it. The design made me feel like I could have different elements interact with eachother without them even being aware of Chapter 28. Boost.Signals2 - 1.55.0 Signals are connected to some set of slots, which are callback receivers (also called event targets or subscribers), which are called when the signal is "emitted." Signals and slots are managed, in that signals and slots (or, more properly, objects that occur as part of the slots) can track connections and are capable of automatically Messaging and Signaling in C++ -
