Feature request from apc.io at https://github.com/apc-io/apc-firefox-os/issues/8

They would like to have a way to disable the soft keyboard (other than via a pref). I guess the nice way would to add an API to navigator.mozInputMethod.mgmt in Gecko to handle this. Should not be very hard.

:yxl, what do you think?

It is reasonable way to add an API for that. But we need Rudy to confirm the requirement before implementation.

Gecko part

I think Rudy is traveling from Canada or something. Anyway, I was in a plane for two hours and didn't have anything to do, so here's the gecko part.

r=me. The code looks good to me.

I prefer to using `false` as default value.

The same. When keyboard is not active, return false.

Can we use the name `enabled` without prefix as that of the `hide()` method? Is the prefix `softKeyboard` necessary?

I don't really agree, the default should be that soft keyboard would pop up as it's the desired behavior for 99,999% of all devices running FxOS at the moment.

Could be, but it misses context. `mgmt.enabled = false` would give me the impression that you can disable the `mgmt` module or something. Let me know if you agree/disagree.
Sorry for late reply.
Yes, we need an API to know if there is an hardware keyboard present for the device.

Does the current implementation conform to what Tim proposed in,

If not, can we counter propose there?

I added comments in the API proposal. We're trying to reach the same path as in the proposal, so let's finish that discussion first before continuing here.
