Specify language when using the chromium-arg '--enable-spell-checking'

Hi,

There doesn’t seem to be any way to specify which language the spellchecker should use when using the chromium-args --enable-spell-checking. For me it always seems to default to en-US.

Does it set this based on the window.navigator.language?

Running nw 0.14.5 on Windows 10.

Thanks

It works like a charm! 😄 Thank you @rogerwang! I just tried in the dev console with nwjs v 0.22.3:

chrome.settingsPrivate.setPref('spellcheck.dictionaries', ["en-US"], "null", console.log.bind(console, "done"));

Now I can even switch the spellcheck language without restarting the app. Great! I guess this deserves mentioning in the api docs?

@dreamsavior I found the comments in the source code here: https://chromium.googlesource.com/chromium/src.git/+/62.0.3178.1/chrome/common/extensions/api/settings_private.idl

But I don’t know of documentation in this case. Perhaps @rogerwang has better knowledge in this area of Chromium’s documentation, but adding it to the documentation for NWjs would be helpful. When I go to “Search docs” and search for “spellcheck”, no pages come up in NWjs here: https://nwjs.readthedocs.io/en/latest/
