Qt4 and system locale

[L.Marvell]

I need to know system locale (en, uk, ru etc.) to load appropriate translation. In Qt3 there was QTextCodec::locale() method for this but Qt4 assistant says:

The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.
Also there is QLocale class that has country(), language() and name() methods in Qt4. But there is no locale().
On my Linux machine countryToString() gives me Default and language() - C, but locale is koi8-u. So how can I get system locale?

Sorry, already did it under win. Will try under Linux at home.

Also there is QLocale class that has country(), language() and name() methods in Qt4. But there is no locale().
QLocale::name() looks promising:

QString QLocale::name () const
Returns the language and country of this locale as a string of the form "language_country", where language is a lowercase, two-letter ISO 639 language code, and country is an uppercase, two-letter ISO 3166 country code.
See also language() and country().


but locale is koi8-u.
IMO that's the encoding, not locale.

Yes, exactly QLocale::name() helped. I had to look through examples before post question. :o

Hi, all!

I have similar problem in qt4 under win.
I want to get system encoding.

So I do:


QTextCodec * localCodec = QTextCodec::codecForLocale();
QByteArray name = localCodec->name();


variable name contain value "System". But I want to get value "cp1251" or "koi8-r" or something else depending of value current local encoding... Value "System" is not informatively.

Anybody know how to get name of current system encoding?

Have you tried QTextCodec::aliases()?

[Sergey]

Yes.
it returns NULL.

[jacek]

Then maybe if you use QTextCodec::mibEnum() first and then get a new codec using QTextCodec::codecForMib() it will have a proper name?

[Sergey]

I wrote next code:


QTextCodec * localCodec = QTextCodec::codecForLocale();
int mib = localCodec->mibEnum();
QTextCodec * codec = QTextCodec::codecForMib(mib);
QByteArray n = codec->name();


variable n contain value "System"...

Maybe this is a bug in QTextCodec?

Maybe this is a bug in QTextCodec?
I think that rather OS doesn't specify what encoding it uses currently.
