Detailed Description#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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 setArguments() ):

arguments = QList()
    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
v = callMyDBusFunction()
# retrieve the D-Bus variant
dbusVariant = QDBusVariant(v)
# retrieve the actual value stored in the D-Bus variant
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.
