Signals and slots have been the cornerstone of Qt programming since atleast Qt 3 or even earlier. I moved from Wx to Qt simply to take advantage of signals and slots back in 2002 and by then it was quite well developed (used macros and a custom C++ pre processor)

They are called ”signals” in Qt but they are a different thing. Qt signals are just places where you can hook callbacks, not observable values.
In that case I would need to send a complaint to my English teacher.
Jokes aside, in Qt, signals come with values. The receiver of a signal receives the changed value.
Signals represent an observable attribute of any object in Qt, and allow to decouple the receiver from the sender.
