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. 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.

Can do in code yes, but can't do this with the signal-slot editor. When I open the signal-slot editor, I see the custom slot on the right but the entire set of slots are disabled.

If QSignalSpy is not able to listen for a valid signal (for example, because obj is nullptr or signal does not denote a valid signal of obj), an explanatory warning message will be output using qWarning() and subsequent calls to isValid() will return false. This constructor is convenient to use when Qt's meta-object system is heavily used in a

Signals and slots are used for communication between objects. The signals The meta-object contains additional information such as the object's class name. The signal/slot mechanism is a central feature of Qt and probably the part that The meta object contains additional information such as the object's class name. Tested with Qt 5.5, mingw 4.9.2, -std=c++98. It relies on transforming a signal or slot name into its index, and then into the associated QMetaMethod.
