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()):
     QList<QVariant> arguments;
     arguments << QVariant(42) << QVariant.fromValue(QDBusVariant(43)) << QVariant("hello");
     myDBusMessage.setArguments(arguments);
When a D-Bus function returns a D-Bus variant, it can be retrieved as follows:
     // call a D-Bus function that returns a D-Bus variant
     QVariant v = callMyDBusFunction();
     // retrieve the D-Bus variant
     QDBusVariant dbusVariant = qvariant_cast<QDBusVariant>(v);
     // retrieve the actual value stored in the D-Bus variant
     QVariant result = dbusVariant.variant();
The QVariant within a QDBusVariant is required to distinguish between a normal D-Bus value and a value within a D-Bus variant.
Constructs a new D-Bus variant.
Constructs a new D-Bus variant from the given Qt variant.
See also setVariant().
Assigns the value of the given Qt variant to this D-Bus variant.
See also variant().
Returns this D-Bus variant as a QVariant object.
