WebA signal is an object that can emit typed notifications, really values parametrized after the signal class template parameters, and register any number of notification handlers … WebA slot does not know if it has any signal(s) connected to it. This is true information encapsulation, and ensures that the object can be used as a true software component. Signals and slots can take any number of arguments of any type. It is possible to connect as many signals as you want to a single slot, and a signal can be connected to as ...
