成员函数文档编制

QLocale:: QLocale ()

构造 QLocale object initialized with the default locale. If no default locale was set using setDefault (), this locale will be the same as the one returned by system ().

另请参阅 setDefault ().

QLocale:: QLocale (const QString & name )

构造 QLocale object with the specified name , which has the format "language[_script][_country][.codeset][@modifier]" or "C", where:

• language is a lowercase, two-letter, ISO 639 language code (also some three-letter codes),
• script is a titlecase, four-letter, ISO 15924 script code,
• country is an uppercase, two-letter, ISO 3166 country code (also "419" as defined by United Nations),
• and codeset and modifier are ignored.

The separator can be either underscore or a minus sign.

If the string violates the locale format, or language is not a valid ISO 639 code, the "C" locale is used instead. If country is not present, or is not a valid ISO 3166 code, the most appropriate country is chosen for the specified language.

The language, script and country codes are converted to their respective Language , Script and Country enums. After this conversion is performed, the constructor behaves exactly like QLocale (Country, Script, Language).

This constructor is much slower than QLocale (Country, Script, Language).

另请参阅 bcp47Name ().

QLocale:: QLocale ( Language language , Country country = AnyCountry)

构造 QLocale object with the specified language and country .

• If the language/country pair is found in the database, it is used.
• If the language is found but the country is not, or if the country is AnyCountry , the language is used with the most appropriate available country (for example, Germany for German),
• If neither the language nor the country are found, QLocale defaults to the default locale (see setDefault ()).

The language and country that are actually used can be queried using language () 和 country ().

另请参阅 setDefault (), language ()，和 country ().

QLocale:: QLocale ( Language language , Script script , Country country )

构造 QLocale object with the specified language , script and country .

• If the language/script/country is found in the database, it is used.
• If both script is AnyScript and country is AnyCountry , the language is used with the most appropriate available script and country (for example, Germany for German),
• If either script is AnyScript or country is AnyCountry , the language is used with the first locale that matches the given script and country .
• If neither the language nor the country are found, QLocale defaults to the default locale (see setDefault ()).

The language, script and country that are actually used can be queried using language (), script () 和 country ().

If Qt Core is using the ICU libraries, they will be used to perform the transformation according to the rules of the current locale. Otherwise the conversion may be done in a platform-dependent manner, with QString::toUpper () as a generic fallback.

该函数在 Qt 4.8 引入。

QStringList QLocale:: uiLanguages () const

Returns an ordered list of locale names for translation purposes in preference order (like "en-Latn-US", "en-US", "en").

The return value represents locale names that the user expects to see the UI translation in.

Most like you do not need to use this function directly, but just pass the QLocale 对象到 QTranslator::load () 函数。

The first item in the list is the most preferred one.

该函数在 Qt 4.8 引入。
