Re: [Boost-users] [signals2] analysing the signature

signal_type::arg<0>::type

Thanks. Originally I tried the following: #include #include int main() { boost::signals2::signal onEvent; typedef BOOST_TYPEOF(onEvent) OnEvent; typedef OnEvent::first_argument_type first; } And it doesn't compile (MSVC9.0) Note that if I add 1 argument, it does compile: //... boost::signals2::signal onEvent; typedef OnEvent::first_argument_type first;
