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. Introduction In GUI programming, when we change one widget, we often want another widget to be notified.
More generally, we want objects of any kind to be able to communicate with one another. For example, if a user clicks a Close button, we probably want the window's close function to be called. Older toolkits achieve this kind of communication using callbacks. A callback is a pointer to a function, so if you want a processing function to notify you about some event you pass a pointer to another function the callback to the processing function. The processing function then calls the callback when appropriate.
Callbacks have two fundamental flaws: Firstly, they are not type-safe. We can never be certain that the processing function will call the callback with the correct arguments. Secondly, the callback is strongly coupled to the processing function since the processing function must know which callback to call. 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. Qt's widgets have many pre-defined slots, but it is common practice to subclass widgets and add your own slots so that you can handle the signals that you are interested in.
