Description:
type-safe Signal Framework for C++ - development files
This library implements a full callback system for use in widget libraries, abstract interfaces, and general programming. It provides the ability to connect an abstract callback to a class method, function, or function object, and contains adaptor classes for the connection of dissimilar callbacks. . These are the development files for libsigc++, needed only if you wish to write software which uses it.
