I was recently frustrated to find that I could not add the gnome "sensors-applet" to the unity bar/panel along the top of the desktop.

Assuming somebody (like me perhaps) wanted to modify an applet like "sensors-applet" (made for gnome desktop) so it could be added to the unity bar/panel, what source-code and/or libraries would I need to write/modify such software?

Could I do something like this by [more-or-less] finding an applet that can be added to the unity bar/panel, rip out that part of the code that puts the icon on the panel, then graft that onto the original "sensors-applet" in place of the equivalent gnome panel code? Or is this idea totally naive?

I think appindicator is what you are looking for

Thanks! I'm reading the documentation to learn more. One question though. Why doesn't someone create an open standard so all future bar/panel applets run on every bar/panel of every future desktop? It seems a shame that all sorts of really great applets become useless just because someone reinvents the bar/panel interface every 2 or 3 years. – honestann Jun 19 '12 at 18:21
The app was probably built as a gnome panel applet instead of an indicator. I don't know why they didn't offer some sort of a compatibility layer to bring exsisting panel applets to unity and gnome 3 but I'm sure they have their reasons why. – Reuben Swartz Jun 19 '12 at 18:26
