returning a pointer to a member function

[Fraser Ross]

Can someone remind me of the syntax for a function that returns a
pointer to a member function? The functions are going to be defined at
the declaration. They will take no parameters. I've given the pointer
members here.

TColor const (TuserInterface ::*
pointerToGetPoi ntColourFunctio n_)(unsigned int const) const;

TColor const (TuserInterface ::*
Get_GetPointCol ourFunctionPoin ter())((unsigne d int) const) const {
return pointerToGetPoi ntColourFunctio n_;
};




void (TuserInterface ::* pointerToSetPoi ntColourFunctio n_)(unsigned int
const, TColor const) const;

void (TuserInterface ::* Get_SetPointCol ourFunctionPoin ter())((unsigne d
int, TColor) const) {
return pointerToSetPoi ntColourFunctio n_;
};

TColor const (TuserInterface ::* Get_GetPointCol ourFunctionPoin ter()
const)(unsigned int) const {
return pointerToGetPoi ntColourFunctio n_;
};
The pointed to function is constant. I appear to have had a syntax
mistake with the constness.

void (TuserInterface ::* Get_SetPointCol ourFunctionPoin ter())(unsigned
int, TColor) {
return pointerToSetPoi ntColourFunctio n_;
};
A similar syntax mistake here I think.

typedef void (MyClass::*pmf) (int);
pmf func()
{
return &MyClass::mem_f unc;
}

If for some reason you don't want to use a typedef, you're on your own.
