The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks. Signals and slots are made possible by Qt's meta-object system. Introduction Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt. In GUI programming, when we change one widget, we often want another widget to be notified.

Not much is done there, the slot is called by either directly calling QObject::qt_static_metacall obtained at the time the connection was established, or QObject::qt_metacall if the QMetaObject::connect was used to setup the connection. The latter allows dynamic creation of signals and slots. Queued Connections

Qt utilise le compilateur de méta-objects (MOC) pour faire fonctionner le signal et la fente (par exemple, effectuer des rappels de fonction basés sur les définitions de signal utilisateur et de slot). Donc, Qt n’est pas C ++, mais c’est vraiment la propre syntaxe de Qt, qui ressemble beaucoup à C ++, mais avec les signaux et les slots.
