How Qt Signals and Slots Work - Part 2 - Qt5 New Syntax This is the sequel of my previous article explaining the implementation details of the signals and slots. In the Part 1 , we have seen the general principle and how it works with the old syntax. 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.
