    if (key() == Qt::Key_AltGr)
        return Qt::KeyboardModifiers(QInputEvent::modifiers()^Qt::GroupSwitchModifier);
    return QInputEvent::modifiers();
}

But I think the Windows platform code may not enable it?

Could key() be returning different values for subsequent if statements? What about doing

k = key();
if (k == Qt::Key_Shift)
etc.
