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

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.
