This library implements a full callback system for use in widget libraries, abstract interfaces, and general programming. Originally part of the Gtk-- widget set, libsigc++ is now a separate library to provide for more general use. It is the most complete library of its kind with the ablity to connect an abstract callback to a class method, function, or function object. It contains adaptor classes for connection of dissimilar callbacks and has an ease of use unmatched by other C++ callback libraries. Package gtkmm, which is a c++ binding to the famous gtk+ library, uses libsigc++. https://libsigc.sourceforge.net/
