Detailed Description

template <typename T_functor, typename... T_obj>
class sigc::track_obj_functor< T_functor, T_obj >

track_obj_functor wraps a functor and stores a reference to a trackable object.

Use the convenience function track_object() to create an instance of track_obj_functor.

track_obj() is a deprecated alternative to track_object().

Template Parameters

T_functor	The type of functor to wrap.
T_obj	The types of the trackable objects.
