QDBusVariant露

PyQt5.QtDBus.QDBusVariant

Description露

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.
