Best practices for boost:signal
What is the best practice for using boost::signal? Should the signal be a public field? Should an accessor method be used? Should there be some special connection methods for every signal, like the following: private: signal<void()> x; public: void connectX(const signal<void()>::slot_type& slot); void disconnectX(const signal<void()>::slot_type& slot); If you use boost:signal, how do you do it? (Okay, actually connectX should return a connection object and disconnectX should take the it as its parameter, but it's about the general idea) -- Memfis

I used public signals in my project (http://vaca.sf.net), but I would like to known what people think about it. Personally, I don't like the idea to have two methods to connect and disconnect slots.

Another practice is to use proxies. This is what they do in gtkmm, albeit with libsigc++ instead of boost::signal, but it's quite similar. -- François Duranleau LIGUM, Université de Montréal

I hardly know what "best practises" to use. I submitted something recently for comments. It tries to be somewhat thread-safe. See [Boost.Signals] in Multithreaded Environment, submitted on Nov 11. (I don't know how to put a link here, sorry). terry begin 666 [Boost.Signals] in Multithreaded Environment.nws M4&%T:#H@;F5W<RYG;6%N92YO<F<A;F]T+69O<BUM86EL#0I&<F]M.B B5&5R
