Does anyone have a code example for python (qt or gtk, doesn't matter) for a status bar application?

By status bar I don't mean the one like the "Clock & Alarms" button, or any other button that appear after you press the status bar itself, but those tiny icons next to the battery and the time, no press is needed.

Applications that do that, as an example, are mStatus applet (which was writted in C, not python) and Tor (which was also written in C).
