The QObject class is the base class of all Qt objects. QObject is the heart of the Qt Object Model. The central feature in this model is a very powerful mechanism for seamless object communication called signals and slots. You can connect a signal to a slot with connect() and destroy the connection with disconnect().

Sometimes when inheritance is problematic, one can replace it, or a part of it, with composition. That's the approach needed in Qt 4: instead of deriving from a QObject, derive from a non-QObject class (MyObjectShared) that carries a helper QObject that is used as a proxy to connect the signal to its slot; the helper forwards that call to the non-QObject class. Signals and Slots - Qt Documentation 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.
