No problem. My point was about not letting user shutdown _easily_. By
this I meant that most people selecting 'Power off' really don't mean
shutdown but something like suspend/standby i.e. pause everything. It is
consumer device. When you pres red button on TV or hi-fi remote you
really don't expect it to poweroff completely and later wait 1 minute
until it powers on again. There should still be shutdown in case you
want to replace battery safely but this will be used rarely (and can be
deliberately a bit more complex like that button combo on ipaq). And my
second point was that in such rare ocassion users might accept that
alarms do not work. But if you implement it, it is better of course :) I
just thought it is hard to do properly (i.e booting up, showing alarm
and then shutting it down) and has little value. If someone has reason
to poweroff it is likely he will not hear the alarm anyway. But it
doesn't hurt of course.
Maybe suspending tasks is not needed after all just send them different
signal so they know device will be paused for many minutes and may wake
up in different environment so they should really finish/stop what they
do. So it is probably about more device modes than current offline or
flight mode (are they same?) and normal.
Introducing something like that would mean that we'd need to modify all
programs to handle custom signals.
By signal I mean message about device mode change. It is already there,
isn't it? It just need more fine-grained control or more modes. And you
need it anyway for implementing that special feature for me below :)
If you want the kind of soft "poweroff" you talk about,
try putting the cover on your device some time...
"Whoops! It pauses video playback! It disconnects network
connections!".
And if you really want the audio playback to be disabled too when
the cover is closed (personally I find it a quite nice that it keeps
playing), we can hack that up just for you, no problem.
Yes the cover is good way to go to this mode but it needs more options.
What if you stream your music from home network and want still listen
with cover on? Or what if you want it to 'soft poweroff' including the
sound because you throw in in the bag then and go somewhere?
All this said, the powerkeymenu is going to be redesigned to allow for
custom actions, and an action that emulates soft powerup by doing
"enable keypadlock + offline mode + pause sound playback" should be
trivial enough to implement.
Excellent. Thank you.
