How do I programmatically detect presence changes in the messaging menu?

Question

Is there a way to subscribe to messaging menu events? Specifically, I'm looking for a signal (over DBus?) that is fired when the online presence status changes in the messaging menu

Answer 1

The messaging menu uses the Telepathy framework and sends the status events to Telepathy's Mission Control. The webpage that describes Telepathy and how it works is here:

• http://telepathy.freedesktop.org/wiki/

If you use the Telepathy-GLib library you're probably looking for the "most-available-presence-changed" signal from the TpAccountManager object.
