I am trying to write a simple widget that will interact with a mail client (at least with Thunderbird) to - record new mail notifications and optionally be able to signal Thunderbird to open a selected mail message. The widget engine I am using(google gadgets for linux) has access to DBUS System and Session buses. As I see it, Thunderbird sends new mail notifications to Gnome via DBUS (?) - how do I capture those signals and what signals should I be looking for? I wanted to start with capturing ALL notifications, and I cannot even get that to work. By poking around I am guessing I need to listen to something in "/org/freedesktop/Notification" but I see no signals under that which make sense. <div> I am really new to DBUS, so I have a feeling I am missing some basic knowledge about DBUS. I tend to learn by doing, so can someone point me in the right direction for doing this (or tell me if I am barking up the wrong tree) Thank you -M </div>
