I use a Car-PC with Debian "Squeeze" with some additional hardware (cam, phone, gps, umts-stick…)
I would like to start a (shell-)script out of the gui.
E.g. for launching xawtv to take a smooth look into my backdrive-cam, the phone-app to start a call, musikplayer and so on.
Doing this by speech should work anymore (with "simon") but that's another thread…
you can do it with a button like this:
<osd enabled="yes" type="button" x="x-pos" y="y-pos" h="height" w="width" command='spawn("argument") src"path to icon file" >
(All in one line)
argument can be a bash script or something. I tried a complete single command line, but this don't work. So you have to use a script.
