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.

Using Enumeration Values as Signal and Method Parameters. C++ signals may pass enumeration values as signal parameters to QML, providing that the enumeration and the signal are declared within the same class, or that the enumeration value is one of those declared in the Qt Namespace. Qt signals and slots for newbies - Qt Wiki There are many problems with them. Qt offer new event-handling system - signal-slot connections. Imagine alarm clock. When alarm is ringing, signal is sending (emitting). And you're handling it as a slot. Every QObject class may have as many signals of slots as you want. You can emit signal only from that class, where signal is. Passing extra arguments to PyQt slots - Eli Bendersky's website
