Deprecated in 2. 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. 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.
Other 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. While successful frameworks using this method do exist, callbacks can be unintuitive and may suffer from problems in ensuring the type-correctness of callback arguments.
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.
The signals and slots mechanism is type safe: The signature of a signal must match the signature of the receiving slot. In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.
Since the signatures are compatible, the compiler can help us detect type mismatches when using the function pointer-based syntax.
The string-based SIGNAL and SLOT syntax will detect type mismatches at runtime. 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.
