A slot is called when a signal connected to it is emitted. Slots are normal C++ functions and can be 

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal. Slots and signals must have same parameters. Otherwise, the connection will not occur. Not only for connection, slot function must have same parameters with signal. For example, this sample doesn’t work: QObject::connect(ui.comboBox, SIGNAL (activated(int)), this, SLOT (onComboboxActivated())); But it works: So, no, signal-slots are not the same as events, they don't accomplish the same thing, and the fact that both exist is critical to the success of Qt. The button example cited completely ignores the general functionality of signal-slot system.

Le problème c'est que j'y connais rien, je débute avec les classes, les déclarations privées, publiques, signaux, slots et je suis un peu perdu. Je ne trouve pas de programme d'exemple complets pour des fonctions simples : Ce que je cherche, c'est un projet complet avec une structure "propre" (j'utilise Qt Creator 5.5 avec MinGW).

The good thing about this is that the subscriber (the slot side) doesn't need to care about details of the signal. It just needs to connect. Thus, here we have a great deal of loose coupling. You can change the buttons implementation, but the interface for the slots would still be the same. Look at Qt Signals/Slots or Boost Signals for more
