template<class t_PROT>
class Signaler
: public Signaler_Invocable<Signaler<t_PROT>, t_PROT>This class template provides a thread-safe signaler that executes connected slots when invoked via its call operator. t_PROT is a function signature and must have a return type of void. The callable objects assigned to the slots may have return types other than void, in which case their return values will be discarded.
