Type-safe Signals and Slots in C++: Part 2

Getting the most of signalslot connections in Qt signal and slot qt The signals and slots mechanism is type safe The signature of a signal must match the signature of the receiving slot signal and slot in qt 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 All classes that inherit from QObject or one of its subclasses, like QWidget can contain signals and slots Signals are emitted by objects when they change
