Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

▼Nsigc	The libsigc++ namespace
Cadaptor_base	A hint to the compiler
Cadaptor_functor	Converts an arbitrary functor into an adaptor type
Cadaptor_trait	Trait that specifies what is the adaptor version of a functor type
Cadaptor_trait< T_functor, false >	Trait that specifies the adaptor version of a functor type
Cadaptor_trait< T_functor, true >	Trait that specifies the adaptor version of a functor type
Cadapts	Base type for adaptors
Cbind_functor	Adaptor that binds arguments to the wrapped functor
Cbind_functor<-1, T_functor, T_type... >	Adaptor that binds argument(s) to the wrapped functor
Cbind_return_functor	Adaptor that fixes the return value of the wrapped functor
Cbound_argument	A bound_argument<Foo> object stores a bound (for instance, with sigc::bind(), or sigc::bind_return()) argument
Cbound_argument< std::reference_wrapper< const T_wrapped > >	Bound_argument object for a bound argument that is passed by bind() or returned by bind_return() by const reference, specialized for const reference_wrapper<> types
Cbound_argument< std::reference_wrapper< T_wrapped > >	Bound_argument object for a bound argument that is passed by bind() or returned by bind_return() by reference, specialized for std::reference_wrapper<> types
Cbound_mem_functor
Ccompose1_functor	Adaptor that combines two functors
Ccompose2_functor	Adaptor that combines three functors
Cconnection	Convenience class for safe disconnection
Cexception_catch_functor
Cfunctor_trait	Trait that specifies the appropriate functor type of any callable type
Chide_functor	Adaptor that adds a dummy parameter to the wrapped functor
Climit_reference	A limit_reference<Foo> object stores a reference (Foo&), but makes sure that, if Foo inherits from sigc::trackable, then visit_each<>() will "limit" itself to the sigc::trackable reference instead of the derived reference
Climit_reference< T_type, true >	Limit_reference object for a class that derives from trackable
Cmem_functor
Cnotifiable
Cpointer_functor	Pointer_functor wraps existing non-member functions with, or without, arguments
Cpointer_functor< T_return(T_args...)>
Cretype_functor	Adaptor that performs C-style casts on the parameters passed on to the functor
Cretype_return_functor	Adaptor that performs a C-style cast on the return value of a functor
Cretype_return_functor< void, T_functor >	Adaptor that performs a C-style cast on the return value of a functor
Cscoped_connection	Convenience class for safe disconnection, including automatic disconnection upon destruction
▼Csignal< T_return(T_arg...)>	Signal can be used to connect() slots that are invoked during subsequent calls to emit()
Caccumulated	Like sigc::signal but the additional template parameter T_accumulator defines the accumulator type that should be used
Csignal_base	Base class for the sigc::signal template
Csignal_with_accumulator	Signal declaration
Cslot< T_return(T_arg...)>	Converts an arbitrary functor to a unified type which is opaque
Cslot_base	Base type for slots
Ctrack_obj_functor	track_obj_functor wraps a functor and stores a reference to a trackable object
Ctrackable	Base class for objects with auto-disconnection
▼Ctrackable_signal< T_return(T_arg...)>	trackable_signal can be used to connect() slots that are invoked during subsequent calls to emit()
Caccumulated	Like sigc::trackable_signal but the additional template parameter T_accumulator defines the accumulator type that should be used
Ctrackable_signal_with_accumulator	Signal declaration
Ctype_trait
Ctype_trait< const T_type & >
Ctype_trait< T_type & >
Ctype_trait< T_type && >

Cunwrap_reference
Cunwrap_reference< std::reference_wrapper< const T_type > >
Cunwrap_reference< std::reference_wrapper< T_type > >
Cvisitor	Sigc::visitor<T_functor>::do_visit_each() performs a functor on each of the targets of a functor
