Merge lp:~vbkaisetsu/unity/bug957927 into lp:unity

[Koichi Akabe]

Ensures hud ignores key presses once ibus is active

I fixed bug #957927
Please merge this branch.

[Marco Trevisan (Treviño) (3v1n0)]

Hi Koichi, thanks for your patch.
However, you need to sign the Canonical Contributor Agreement to get it merged.

[Koichi Akabe (vbkaisetsu)]

Hi,
Thank you for your information.
I sent the CCA on the internet just now.

[Marco Trevisan (Treviño) (3v1n0)]

Ok, the agreement is there.
So, I guess we need to wait the nux branch to be merged.

[Alex Launi (alexlauni)]

This needs a test. It should be very simple to write an autopilot test to ensure that this does not regress. Please ping me, or anyone else on irc if you need help with autopilot testing.

review: Needs Fixing

[Koichi Akabe (vbkaisetsu)]

Hi Alex,
I added autopilot codes for ibus-anthy and ibus-pinyin. But I didn't add for ibus-hangul because it commits hangul on input components.

Please review it.

[Gord Allott (gordallott)]

+1 here

review: Approve

[Marco Trevisan (Treviño) (3v1n0)]

This needs to be merged with trunk, other than that it's fine.

[Koichi Akabe (vbkaisetsu)]

It has many changes, but I think it was merged correctly.

[Brandon Schaefer (brandontschaefer)]

Looks good to me. +1.
