RE: Confusing about DBus API specification

Dear Jirka, 

It's weird. After adjusting my script, it's still error: 

[Here is new script:]
#!/usr/bin/env python

import dbus
bus = dbus.SystemBus()

proxy = bus.get_object("org.freedesktop.NetworkManager",
"/org/freedesktop/NetworkManager")
proxy_prop = dbus.Interface(proxy, "org.freedesktop.DBus.Properties")
manager = dbus.Interface(proxy, "org.freedesktop.NetworkManager")


#proxy_user_setting =
bus.get_object("org.freedesktop.NetworkManagerUserSettings",
"/org/freedesktop/NetworkManagerUserSettings")
proxy_sys_setting =
bus.get_object("org.freedesktop.NetworkManagerSystemSettings",
"/org/freedesktop/NetworkManagerSystemSettings")
settings = dbus.Interface(proxy_sys_setting,
"org.freedesktop.NetworkManagerSettings")

print "========= active connection"
connections = proxy_prop.Get("org.freedesktop.NetworkManager",
"ActiveConnections")
print "%d" % proxy_prop.Get("org.freedesktop.NetworkManager",
"WirelessHardwareEnabled")
print "%d" % proxy_prop.Get("org.freedesktop.NetworkManager",
"WirelessEnabled")
print "%d" % proxy_prop.Get("org.freedesktop.NetworkManager", "State")
for con in connections:
	print "xxxx %s" % con
	con_obj = bus.get_object("org.freedesktop.NetworkManager", con)

print "========== list connection "
connections = settings.ListConnections()
for con in connections: 
	print "%s" % con



[Here is log:]

Please help.

ListConnections() method is not provided by /org/freedesktop/NetworkManager 
service, rather /org/freedesktop/NetworkManagerSystemSettings and 
org.freedesktop.NetworkManagerUserSettings.
See inline comments to adapt your script.

add here
proxy1 = bus.get_object("org.freedesktop.NetworkManagerUserSettings", 
"/org/freedesktop/NetworkManagerSettings")
for listing user connections or
proxy1 = bus.get_object("org.freedesktop.NetworkManagerSystemSettings", 
"/org/freedesktop/NetworkManagerSettings")
for listing system-wide connections.

You need to use proxy1 here instead of proxy.
settings = dbus.Interface(proxy1, "org.freedesktop.NetworkManagerSettings")

this line should look like this:
connections = settings.ListConnections()

i.e. using settings interface and no arguments to ListConnections()
