Dbus signals and knowing the activated connection

[Pietro Battiston <me pietrobattiston it>]

Hello,

I'd like to some apparently simple thing with nm dbus signals:

1) get warned that a connection has been activated
2) do something based on _which_ connection it is.

Unfortunately all I was able to do so far is:

1) get warned that a connection has been activated (by listening at the
dbus interface "org.freedesktop.NetworkManager.Connection.Active")
2) find out which connections are currently active (by getting the
"ActiveConnections" list from "org.freedesktop.NetworkManager")
3) pick one of them, not knowing which was just activated rather than
being already active before.


Basically, I'm currently combining
http://blog.g00se.org/2009/01/getting-dbus-messages-from.html
with
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/nm-state.py

Is there something obvious that I missed?

Or maybe the right question should be: since among the properties of
http://projects.gnome.org/NetworkManager/developers/api/09/spec.html#org.freedesktop.NetworkManager.Connection.Active
there is also "Connection", why does the dictionary received by the
signal handler of signal "PropertiesChanged" when a connection is
activated contain only parameters "Default" and "State"?

thanks in advance

Pietro
