    \brief The QDBusVariant class enables the programmer to identify
    the variant type provided by the D-Bus typesystem.

    A D-Bus function that takes an integer, a D-Bus variant and a string as parameters
    can be called with the following argument list (see QDBusMessage::setArguments()):

    \snippet qdbusextratypes/qdbusextratypes.cpp 0

    When a D-Bus function returns a D-Bus variant, it can be retrieved as follows:

    \snippet qdbusextratypes/qdbusextratypes.cpp 1

    The QVariant within a QDBusVariant is required to distinguish between a normal
    D-Bus value and a value within a D-Bus variant.
