[Qt-interest] Enumerations: 'qt_metatype_id' is not a member of ...

[Schimkowitsch Robert]

I find myself unable to get rid of the following error message:

qmetatype.h:169: error: 'qt_metatype_id' is not a member of
'QMetaTypeId<CCmn_UIUpdateTimer::EUiActivityMode>'

My main.cpp looks like this:

#include <QApplication>
#include <QVariant>
#include <QMetaEnum>
#include <QMetaObject>
#include <QDebug>
#include "cmn_uiupdatetimer.h"
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    CCmn_UIUpdateTimer::EUiActivityMode activityMode =
CCmn_UIUpdateTimer::eUiOff;
    QVariant vActivityMode;
    vActivityMode.setValue(activityMode);  // << ERROR LINE
    qDebug() << vActivityMode;
    return a.exec();
}

The header file "cmn_uiupdatetimer.h" has been stripped of all code, and
looks like this:

#include <QObject>
#include <QMetaType>
#include <QMetaEnum>
class CCmn_UIUpdateTimer : public QObject
{
    Q_OBJECT
    Q_ENUMS(EUiActivityMode)
public:
    enum EUiActivityMode
    {
        eUiOff = 0,
        eUiActive = 1
    };
};
Q_DECLARE_METATYPE(CCmn_UIUpdateTimer*)

I have declared the enum EUiActivityMode using Q_ENUMS. Why doesn't that
work?

Kind regards
