libsigc++ implements a typesafe callback system for standard C++. It allows you to define signals and to connect those signals to any callback function, either global or a member function, regardless of whether it is static or virtual.

libsigc++ is used by glibmm and gtkmm to wrap Glib and GTK+ signals. It does not depend on Glib, GTK+, glibmm or gtkmm.

libsigc++-3.0 API is a new API which installs in parallel with libsigc++-2.0. The API is not significantly different from libsigc++-2.0 but the implementation is far simpler, using variadic templates instead of generating C++ code from .m4 files.

libsigc++-3.0 requires a compiler with C++14 support.

*** Changes

2.99.2 (unstable):

• slots and signal: These should now be declared with the sigc::slot<R(Args...)> and sigc::signal<R(Args...)> syntax, like std::function<>. Version 2.9/2.10 of libsigc++-2.0 supports both the old and new syntax. (Murray Cumming)
• sigc::men_fun(): Take the instance by reference only.
