Compiler Warning (level 4, off) C4263

  • Artikkeli

'function' : member function does not override any base class virtual member function

A class function definition has the same name as a virtual function in a base class but not the same number or type of arguments. This pattern effectively hides the virtual function in the base class.

This warning is off by default. For more information, see Compiler Warnings That Are Off by Default.

The following sample generates C4263:

// C4263.cpp
// compile with: /W4
#pragma warning(default:4263)
#pragma warning(default:4264)
class B {
public:
   virtual void func();
};

class D : public B {
   void func(int);   // C4263
};

int main() {
}
