Thanks, but no. What I'm passing in is the keys for the dictionary I get as a
result of this code:
io_connect_t thePort = CGDisplayIOServicePort(theScreenNumber);
CFDictionaryRef theInfo =
(CFDictionaryRef)IODisplayCreateInfoDictionary(thePort, 0);
CFDictionaryRef theNames = CFDictionaryGetValue(theInfo,
CFSTR(kDisplayProductName));
theNames will look something like this:
"en_US" -> "Color LCD"
"en_GB" -> "Colour LCD"
"fr_FR" -> "LCD couleur"
....
My workaround for the moment is to use NSLocale's currentLocale method, and if
I don't find a key matching that I'll loop over the preferred language list
until I find a key that has the language under consideration as a prefix.
Problem is that seems needlessly convoluted and if I do end up with a
dictionary that has multiple locales for the same language I'll essentially be
picking among them at random. As I'm typing I've realized that the rest of the
system uses the language list in preference to the current locale, though, so I
have to fix that anyway.
