[maemo-developers] Making my app. appear on the Navigator menu

Thank you very much for your valuable feedback!

But shouldn't "most" applications provide a D-BUS service so that they can receive system messages (low battery, shutdown, screen blanking) and gracefully handle them? (kind of best practice??)

Whew - this clears it up. mClock currently is a pure Pygame thing, so that's why the WM_CLASS was needed. Now I understand. I was confused because:
- I read somewhere about the use of WM_CLASS not being necessary anymore
- Some apps I dissected had the WM_Class in their .desktop file, but nowhere in their app code, so it seemed unused (probably because they were GTK apps)

So I now fixed this and the icon shows up in the TN. Cool :-)
However, the TN still doesn't know the NAME of my app! (Fortunately, I'm not alone with this problem - UKMP has the same issue as I saw by coincidence)
-When in normal mode, pressing the Home icon brings up TN with my mClock icon, but named as "unknown"
-When in Fullscreen mode, pressing the Home icon brings up TN with my mClock icon, but named as "<unnamed>" (just like with UKMP)
What is missing now? How can I tell TN the name of my App?

Thanks again!
