Re: [Boost-users] [signals2] Connect to overloaded slots

Florian Lindner via Boost-users писал 2017-11-10 15:54:

Hello,

Hi,

this code compiles just fine:

#include #include <iostream>

// void slot() { std::cout << "No args slot called." << std::endl; } void slot(int i) { std::cout << "Int " << i << " arg slot called." << std::endl; }

int main(int argc, char **argv) { boost::signals2::signal s; s.connect(&slot);

return 0; }

However, when I uncomment the slot() function, it does not do so, anymore:

boostsignals.cpp:78:5: error: no matching member function for call to 'connect' s.connect(&slot); ~~^~~~~~~ /usr/include/boost/signals2/detail/signal_template.hpp:689:18: note: candidate function not viable: no overload of 'slot' matching 'const boost::signals2::signal, boost::function, boost::signals2::mutex>::slot_type' (aka 'const slot >') for 1st argument connection connect(const slot_type &slot, connect_position position = at_back) ^ /usr/include/boost/signals2/detail/signal_template.hpp:693:18: note: candidate function not viable: requires at least 2 arguments, but 1 was provided connection connect(const group_type &group, ^

Is there a way to make it working with overloaded slot functions?
