Question

I have this enum in Item class

 enum EquipSlot
{
RightHand,
Head,
...
};

character class has this function declaration

void Character::UnequipSlot(Item::EquipSlot slot);

item class is not in any namespace or a part of another class.

i use Item::EquipSlot in implementation a lot with no error. it only gives compile error while in declaration.

What’s the correct way to call enum of another class?

(compiler is vc++ 9)
error is : error C2027: use of undefined type ‘Item’ (item class is used in other declarations)

thanks.

Answer 1

Include the header that defines Item.

If Item is only declared, Item may be used in some contexts, but not when the size or contents of Item are required.
