Adding USBNetworking Icon to StatusBar (catch lipc-set-prop event with nativeBridge)

[MaPePeR]

Hello,

i thought it would be nice to see the state of the USB Networking next to the Wifi Icon, so i tried to find the place, where the status bar is defined.

i was successful:
There is a html file at /usr/share/webkit-1.0/pillow/default_status_bar.html which holds the layout for the status bar.

also several .js files:

/usr/share/webkit-1.0/pillow/javascripts/default_status_bar.js
/usr/share/webkit-1.0/pillow/javascripts/default_status_bar_connection.js
/usr/share/webkit-1.0/pillow/javascripts/default_status_bar_activity.js
/usr/share/webkit-1.0/pillow/javascripts/default_status_bar_audio_icon.js
/usr/share/webkit-1.0/pillow/javascripts/default_status_bar_battery.js

this .js files uses

nativeBridge.subscribeToEvent(src.name, event.name);
nativeBridge.registerEventsWatchCallback(StatusBar.eventsCallback);
nativeBridge.registerClientParamsCallback(StatusBar.clientParamsCallback);

But i havent got a clue, how i can catch the lipc-event, that is fired by the usbnetwork.sh file

${LIPC_SET_PROP} -i -- com.lab126.volumd useUsbForNetwork ${USE_USBNET}

(or at least i couldn't catch it with lipc-wait-event)

Any tipps?
Which of the register/subscribe functions should i use in the js file to be informed about that event?
