Creating an enum like structure for data types other than integral?

[fcarney]

When creating enums we can get do something like this:

enum Vals{
    Val1,
    Val2,
    Val3
};

Then access them Vals::Val2.
I wanted something similar, but for strings. The closest I could get was this:

struct Token{
    QString Invalid = " ";
    QString P1 = "X";
    QString P2 = "O";
} tokens;

Then accessing them like this: tokens.P1

Are there other, better ways to make enum like structures for data types other than integrals?
I could also use a map, hash, etc of course. I just like the Enum::Value syntax.

Not really, but you can "improve" your struct based solution by making the members static: then you don't have to create an instance of the struct and you can do:

Token::Invalid

Also, since enum values cannot be changed you should make the struct elements const:

struct Token{
    static const QString Invalid;
    static const QString P1;
    static const QString P2;
}

const QString Token::Invalid = " ";
const QString Token::P1 = "X";
const QString Token::P2 = "O";
