libsigc++: LibSigC++ (Typesafe callback system for C++) libsigc++: libsigc++: libsigc++ implements a typesafe callback system for standard C++. libsigc++: It allows you to define signals and to connect those signals to libsigc++: any callback function, either global or a member function, libsigc++: regardless of whether it is static or virtual. It also contains libsigc++: adaptor classes for connection of dissimilar callbacks and has libsigc++: an ease of use unmatched by other C++ callback libraries. libsigc++: libsigc++: libsigc++: Packaged by Georgi D.
