<![CDATA[pointer-to-memberfunction + typedef]]>Hi,
Hab ein Problem mit memberfunction-pointer/typedefs.
Sieht jemand, woran es scheitert?

template <class Class>
struct memfun_type {
  typedef void (Class::*draw_ptr_type)();
  typedef void (Class::*reshape_ptr_type)(int, int);
};

template <class Class>
struct memfun_holder {
  memfun_type<Class>::draw_ptr_type draw_ptr;       // error: expected `;' before "draw_ptr"
  memfun_type<Class>::reshape_ptr_type reshape_ptr; // error: expected `;' before "reshape_ptr"
};

template <class Class>
struct memfun_type {
  typedef void (Class::*draw_ptr_type)();
  typedef void (Class::*reshape_ptr_type)(int, int);
};

template <class Class>
struct memfun_holder {
  typename memfun_type<Class>::draw_ptr_type draw_ptr;
  typename memfun_type<Class>::reshape_ptr_type reshape_ptr;
};
