Testing C++ signal-slot libraries by Julien Jorge In Qt's Signal and slots architecture the receiving slot can actually have fewer parameters than the emitted signal, the extra arguments will

And when there is a free standing function there is a signature, but there is no instance, so the third and the fourth arguments of the first
