Q_ENUMS outside of the class?

[stefan]

Hi all!

I want to use type safe enumeration like in C++11

enum class Fruit
{
    apple,
    orange,
    pear
}

enum class Fruit
{
    apple,
    orange,
    pear
}

To copy to clipboard, switch view to plain text mode 

and use it in more (then one) classes

class FruitCake
{
    Fruit baseFruit; //use: baseFruit = Fruit::apple;
}
class Person
{
   Fruit favoriteFruit; //use: favoriteFruit = Fruit::apple;
}
 
if(john.favoriteFruit == myCake.baseFruit)
    john.eat(myCake)

class FruitCake
{
    Fruit baseFruit; //use: baseFruit = Fruit::apple;
}
class Person
{
   Fruit favoriteFruit; //use: favoriteFruit = Fruit::apple;
}

if(john.favoriteFruit == myCake.baseFruit)
    john.eat(myCake)

To copy to clipboard, switch view to plain text mode 

OK, this can be done easily. But I want all the goodies that Q_ENUMS provides (The meta data of enum).
How can i do that?

Sorry for non-imaginative example

Q_ENUMS is processed by MOC, so it needs to be in a class that is QObject derived and has a Q_OBJECT marker.

Or you can try Q_GADGET on your enum class

Q_GADGET is only mentioned in passing in the QObjectvdocs. I suspect it will not well in the enum class.

Thanks for your answers.
I think that I will adjust my design and go with Qt style (QObject class with Q_ENUMS)
