How to pass enumerator type as a signal paramater in Qt

Question

I have a header file where i have:

enum event {UP, DOWN, LEFT, RIGHT, ACTION };

and I have Q_OBJECT class where I want to pass event type "events" as a signal paramater.

class GameView : public QGraphicsView {
            Q_OBJECT
            public:
                GameView(QWidget* parent, GameModel *m);
            ...
            signals:
                void sendEvent(event e);
            ...
};

But when I try to build it, the compiler says

'event' is not a type.

How can i pass the enumerator as a type correctly for the signal?

Is it the compiler? Is it moc? What's the *complete* error message? — peppe, Mar 25 '17 at 17:24

It is not a matter of signals or Qt. It is pure C++.

event is a member function of QGraphicsView. So when you write void sendEvent(event e);, event is not a type but a function.

You could write void sendEvent(::event e); which will force to resolve event at global scope.
