## Detailed Description

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

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

Template Parameters

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

Since libsigc++ 2.4:
