%description
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++20 is now a separate library to provide for more general
use. 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 connection of dissimilar callbacks and has an
ease of use unmatched by other C++ callback libraries.
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.
Package GTK-- (gtkmm), which is a C++ binding to the GTK+ library,
starting with version 1.1.2, uses libsigc++20.
libsigc++ is used by gtkmm to wrap the GTK+ signal system. It does not
depend on GTK+ or gtkmm.
