libsigc++
From Wikipedia, the free encyclopedia
Libsigc++ is a C++ library for typesafe callbacks.
'libsigc++' implements a full callback system for use in abstract interfaces and general programming. It is the most complete library of its kind with the ability to connect an abstract callback to a class method, function, or function object. It contains adaptor classes for connecting dissimilar callbacks and has an ease of use unmatched by other C++ callback libraries.
