Detecting OS language within browser

[newaira]

So I'm trying to figure out what is the best approach to detecting what is the current OS language. From what I've read and tried so far, it looks like CEF starts up without in any way trying to figure out what is the currently selected OS language. It always defaults to --lang=en-US.

I can get the lang value from Javascript by calling navigator.language, so it's good that I can access it.

Now, what would be the best approach to set the --lang/CefSettings.locale to the correct OS language? Do I need to make native system calls myself in order to get the current language, or is there something that's already built-in?

You will need to make the system call yourself.

In case someone needs to do the same, here is how I did it on windows. You might want to add some error checks.

Would it be useful to include this kind of logic in the core rather than always defaulting to en_US?

Code: Select all

CefSettings settings;

// set language based on user's default lang
LANGID langId = GetUserDefaultLangID();

wchar_t languageCode[100];
GetLocaleInfo(langId, LOCALE_SISO639LANGNAME, languageCode, 100);
wchar_t countryCode[100];
GetLocaleInfo(langId, LOCALE_SISO3166CTRYNAME, countryCode, 100);

std::wstring lang(languageCode);
lang += L"_" + std::wstring(countryCode);

CefString(&settings.locale).FromWString(lang);


I'm also going to do it for OS X.
