unmount is the only valid option.

Indeed it does work as:

arg = QtDBus.QDBusArgument()
arg.beginArray(QMetaType.QString)
arg.add(unmount)
arg.endArray()


and so does:

arg = QtDBus.QDBusArgument()
arg.beginArray(QMetaType.QString)
arg.endArray()

Experimenting with other calls shows this is the way to create an empty 
Array of Strings.

The current snapshot also allows...

Try this...

arg = QDBusArgument()
arg.beginArray(QMetaType.QString)
arg.add()
arg.endArray()

...and pass arg to call().

If that works I'll change QDBusArgument so that you can do...

   call(DeviceEject, QDBusArgument([], QMetaType.QStringList))

[PyQt] QtDBus: Calling a method with an Array of Strings signature with Python 3

2011-12-04 Thread Chris Mayo


With Python 2 I can do (where /dev/sr0 is a cdrom):

bus = QtDBus.QDBusConnection.systemBus()
device_iface = QtDBus.QDBusInterface('org.freedesktop.UDisks',
	'/org/freedesktop/UDisks/devices/sr0', 'org.freedesktop.UDisks.Device', 
bus)

reply = device_iface.call(DriveEject, QStringList())


But with Python 3 this won't work because of QStringList. If I modify it 
with:


reply = device_iface.call(DriveEject, [, ])
print(reply.errorMessage())

I get:

Method DriveEject with signature av on interface 
org.freedesktop.UDisks.Device doesn't exist
