Done.

nit: deleting a null pointer is fine, so you can remove the if statement.  also
suggest setting widget_ to NULL afterwards

[alicet1, 2011/10/20 22:36:30]

Done.

[Daniel Erat, 2011/10/20 15:43:39]

nit: comment style i've seen more frequently for parameters in chrome is

  StartFade(false /* fade_in */);

[Daniel Erat, 2011/10/20 15:43:39]

does this mean that we start fading the bubble out immediately?  if so, i don't
think that that's desired -- we should show it at full opacity for a bit and
then fade it out quickly

[alicet1, 2011/10/20 22:36:30]

Done.

[alicet1, 2011/10/20 22:36:30]

yup, changed.

Is this called anywhere?

[alicet1, 2011/10/20 22:36:30]

yeah, in SystemKeyEventListener::ShowVolumeBubble, we end with a hide on
brightness bubble there.
