## Detailed Description

### template<class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_arg5, class T_arg6, class T_arg7, class T_return>
class sigc::pointer_functor7< T_arg1, T_arg2, T_arg3, T_arg4, T_arg5, T_arg6, T_arg7, T_return >

pointer_functor7 wraps existing non-member functions with 7 argument(s).

Use the convenience function ptr_fun() to create an instance of pointer_functor7.

The following template arguments are used:

- T_arg1 Argument type used in the definition of operator()().
- T_arg2 Argument type used in the definition of operator()().
- T_arg3 Argument type used in the definition of operator()().
- T_arg4 Argument type used in the definition of operator()().
- T_arg5 Argument type used in the definition of operator()().
- T_arg6 Argument type used in the definition of operator()().
- T_arg7 Argument type used in the definition of operator()().
- T_return The return type of operator()().
