for more general solution check boost::signals library
it is a type safe callback library
you can also check battle tested libsigc++
Right, but note that unlike boost::function and boost::bind,
boost::signals is not part of std::tr1 (some employers eschew Boost or
at least non-TR1 Boost). Which of these solutions is best will depend
on the OP's needs, I suppose.
(you spend most of your time designing
your program, typing five extra characters
should not be such a chore. Injecting whole
of std into your namespace is never a good
idea)
//using namespace std;
_Never_? I disagree just because of the absoluteness and universality
of your advice. Moreover, gurus Sutter and Alexandrescu say in _C++
Coding Standards_, item 59 (italics in original): "You can and should
use namespace using declarations and directives liberally _in your
implementation files after #include directives_ and feel good about
it. Despite repeated assertions to the contrary, namespace using
declarations and directives are not evil and they do not defeat the
purposes of namespaces. Rather, they are what make namespaces usable."
