(De-)Serializing outer enums about qtjsonserializer HOT 3 CLOSED

I'm not exactly shure what you are asking, but I'll try to answer anyways.

Where the Enum is defined does not really matter for serializing, as long as the Q_ENUM macro is used (which it is for your example). Now all that needs to be done is declare the Q_PROPERTY with the enums full qualified name as type:

struct MySecondGadget
{
    Q_GADGET

    Q_PROPERTY(MyEnumWrapper::Enum myEnumField MEMBER myEnumField)

public:
    MyEnumWrapper::Enum myEnumField;
};

Q_DECLARE_METATYPE(MySecondGadget)

To ensure it works as intended, you should also register the gadget wrapper as metatype (As you should do with all your gadgets). Use Q_DECLARE_METATYPE(MyEnumWrapper) in the header and qRegisterMetaType<MyEnumWrapper>(); in your main.cpp. Finally, use the setEnumAsString(true); as you already mentioned, and your good to go.

Note: In case you have to use flags, use Q_PROPERTY(MyEnumWrapper::Flags myflagsField READ getField WRITE setFiled) instead, as member access for flags is broken. But for classic enums, using the member should suffice.

Thank you for your full answer. BTW, I've tried to disable Q_DECLARE_METATYPE(MyEnumWrapper) and qRegisterMetaType<MyEnumWrapper>();. It worked even without them.

Good to know. It's sometimes hard to know what works with the registrations and what not. Thats why I just always add them, to be on the safe side.
