29.43 warn_hidevirtual

Controls the recognition of a non-virtual member function that hides a virtual function in a superclass.

Syntax

#pragma warn_hidevirtual on | off | reset

Remarks

If you enable this pragma, the compiler issues a warning message if you declare a nonvirtual member function that hides a virtual function in a superclass. One function hides another if it has the same name but a different argument type.

Listing 29-14 on page 454

shows an example.

Listing 29-14. Hidden Virtual Functions

class A {

public:

virtual void f(int);

virtual void g(int);

}; class B: public A {

public:

void f(char); // WARNING: Hides A::f(int)

virtual void g(int); // OK: Overrides A::g(int)

};

The ISO/IEC 14882:2003 C++ Standard does not require this pragma.

NOTE

A warning message normally indicates that the pragma name is not recognized, but an error indicates either a syntax problem or that the pragma is not valid in the given context.

This pragma corresponds to the Hidden Virtual Functions setting in the CodeWarrior
