kamils has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I'd like to use Net::DBus to connect to a client of evince (pdf viewer) to make it sync to a document. My problem is that, being a client, it does not have a fixed name. It is just assigned a number such as ":1.10". I know how to get a list of all services, but I don't know how to find which one contains the "/org/gnome/evince/Window/0" object. Can you help me, please?
