isn't it a daemon?
it checks if it's open or not.. !? so it'll check every X seconds to show the status, or am I wrong?

No, it is not a daemon.

It is a plugin module for the statusbar. Most of the time it does absolutly
nothing. It only registers function to be called on some events.
(open/close the lens cover and the screen lock).

Great! I actually made a DECW widget to do something similar, but this is way better! :D

One possible piece of cool intelligence would be to set a timer after the vibration and recheck the status, then play a sound if it's still open after say 10 seconds.

Another cool feature would be to set a similar timeout to take a brightness reading from the camera (is it possible?) or take photo and analyse the darkness. If it is dark (like in a pocket, laying on a table etc) then it is probably covered and you really want to close the lens cover as it is at high risk of scratching/dust getting in, so then the sound should be played.

(and for those who don't want sound, they can set it to off, or a silent sound file)

@benh_n900:
Check after a determinated time needs a timer, and it will drain the battery

@nicolai:
Try hildon_play_system_sound()

Linux is an event driven system. You don't need to actively track time. Just tell the kernel "please wake me up in X seconds" and go to sleep. :)

You may see g_timeout_add () for more details.

Good synthesis. I like the idea.

Rather complicated for something that you can just check by reading the proximity sensor's state.

This happens to me all the time, so thanks for this small but hugely useful app !

Brilliant :) Very needed indeed... Constantly forget to close it, mostly because im used to a digi cam that covers the lens automaticly when off :)

Thx for sharing your work with us :)

But maybe its time for the mobile developers to take a look at the digital camera designs out there... an auto open/close lens cover system has been used for years now... maybe its time to move this system to the mobile phones aswell :)
