The Signal Engineer

The Signal Engineer signal slot Using arbitrary methods as slots Any method of any class can be used as a slot, even if never written specifically for being a slot The only requirement is signal and slot arguments are not compatible 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

signal and slot arguments are not compatible Un slot est appelé quand un signal qui lui est connecté est émis Les slots sont des fonctions C++ normales et peuvent être appelés normalement ; leur seule
