Is there a cleaner way to register Qt custom events?

I need to create several custom event classes for a Qt application.

Right now, it looks like I will need to implement the following event type registration code for each event class:

class MyEvent : public QEvent
{
public:
    MyEvent() : QEvent(registeredType())
    {
    }

    static QEvent::Type eventType;

private:
    static QEvent::Type registeredType();
}

QEvent::Type MyEvent::eventType = QEvent::None;

QEvent::Type MyEvent::registeredType()
{
    if (eventType == QEvent::None)
    {
        int generatedType = QEvent::registerEventType();
        eventType = static_cast<QEvent::Type>(generatedType);
    }
    return eventType;
}

Any suggestions on how I can simplify this, or at least hide it with a macro?
