Detailed Description

The QLocale class converts between numbers and their string representations in various languages.

QLocale is initialized with a language/country pair in its constructor and offers number-to-string and string-to-number conversion functions similar to those in QString.

Example:

QLocale egyptian(QLocale::Arabic, QLocale::Egypt);
QString s1 = egyptian.toString(1.571429E+07, 'e');
QString s2 = egyptian.toString(10);

double d = egyptian.toDouble(s1);
int i = egyptian.toInt(s2);

QLocale supports the concept of a default locale, which is determined from the system's locale settings at application startup. The default locale can be changed by calling the static member setDefault(). Setting the default locale has the following effects:

If a QLocale object is constructed with the default constructor, it will use the default locale's settings.
QString::toInt(), QString::toDouble(), etc., interpret the string according to the default locale. If this fails, it falls back on the "C" locale.
QString::arg() uses the default locale to format a number when its position specifier in the format string contains an 'L', e.g. "%L1".

The following example illustrates how to use QLocale directly:

QLocale::setDefault(QLocale(QLocale::Hebrew, QLocale::Israel));
QLocale hebrew; // Constructs a default QLocale
QString s1 = hebrew.toString(15714.3, 'e');

bool ok;
double d;

QLocale::setDefault(QLocale::C);
d = QString("1234,56").toDouble(&ok);   // ok == false
d = QString("1234.56").toDouble(&ok);   // ok == true, d == 1234.56

QLocale::setDefault(QLocale::German);
d = QString("1234,56").toDouble(&ok);   // ok == true, d == 1234.56
d = QString("1234.56").toDouble(&ok);   // ok == true, d == 1234.56

QLocale::setDefault(QLocale(QLocale::English, QLocale::UnitedStates));
str = QString("%1 %L2 %L3")
      .arg(12345).arg(12345).arg(12345, 0, 16);
// str == "12345 12,345 3039"

When a language/country pair is specified in the constructor, one of three things can happen:

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()).

Use language() and country() to determine the actual language and country values used.

An alternative method for constructing a QLocale object is by specifying the locale name.

QLocale korean("ko");
QLocale swiss("de_CH");

This constructor converts the locale name to a language/country pair; it does not use the system locale database.

Note: For the current keyboard input locale take a look at QApplication::keyboardInputLocale().

QLocale's data is based on Common Locale Data Repository v2.0.

enum QLocale::CurrencySymbolFormat

Specifies the format of the currency symbol.

Constant	Value	Description
`QLocale::CurrencyIsoCode`	`0`	a ISO-4217 code of the currency.
`QLocale::CurrencySymbol`	`1`	a currency symbol.
`QLocale::CurrencyDisplayName`	`2`	a user readable name of the currency.

This enum was introduced or modified in Qt 4.8.

enum QLocale::FormatType

This enum describes the types of format that can be used when converting QDate and QTime objects to strings.

Constant	Value	Description
`QLocale::LongFormat`	`0`	The long version of day and month names; for example, returning "January" as a month name.
`QLocale::ShortFormat`	`1`	The short version of day and month names; for example, returning "Jan" as a month name.
`QLocale::NarrowFormat`	`2`	A special version of day and month names for use when space is limited; for example, returning "J" as a month name. Note that the narrow format might contain the same text for different months and days or it can even be an empty string if the locale doesn't support narrow names, so you should avoid using it for date formatting. Also, for the system locale this format is the same as ShortFormat.

enum QLocale::Language

This enumerated type is used to specify a language.

Constant	Value	Description
`QLocale::AnyLanguage`	`0`
`QLocale::C`	`1`	The "C" locale is identical in behavior to English/UnitedStates.

Member Function Documentation

QLocale::QLocale()

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

See also setDefault().

QLocale::QLocale(const QString & name)

Constructs a 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,
script is a titlecase, four-letter, ISO 15924 script code,
country is an uppercase, two- or three-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 369 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).

See also bcp47Name().

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

Constructs a 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() and country().

See also setDefault(), language(), and country().

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

Constructs a 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() and country().

This function was introduced in Qt 4.8.

See also setDefault(), language(), script(), and country().

bool ok;
double d;

QLocale c(QLocale::C);
d = c.toDouble( "1234.56", &ok );  // ok == true, d == 1234.56
d = c.toDouble( "1,234.56", &ok ); // ok == true, d == 1234.56
d = c.toDouble( "1234,56", &ok );  // ok == false

QLocale german(QLocale::German);
d = german.toDouble( "1234,56", &ok );  // ok == true, d == 1234.56
d = german.toDouble( "1.234,56", &ok ); // ok == true, d == 1234.56
d = german.toDouble( "1234.56", &ok );  // ok == false

d = german.toDouble( "1.234", &ok );    // ok == true, d == 1234.0

Notice that the last conversion returns 1234.0, because '.' is the thousands group separator in the German locale.

If base is 0 the base is determined automatically using the following rules: If the string begins with "0x", it is assumed to be hexadecimal; if it begins with "0", it is assumed to be octal; otherwise it is assumed to be decimal.

If the conversion fails the function returns 0.

If ok is not 0, failure is reported by setting *ok to false, and success by setting *ok to true.

This function ignores leading and trailing whitespace.

See also toLongLong(), toInt(), toDouble(), and toString().

ushort QLocale::toUShort(const QString & s, bool * ok = 0, int base = 0) const

Returns the unsigned short int represented by the localized string s, using base base. If base is 0 the base is determined automatically using the following rules: If the string begins with "0x", it is assumed to be hexadecimal; if it begins with "0", it is assumed to be octal; otherwise it is assumed to be decimal.

If the conversion fails the function returns 0.

If ok is not 0, failure is reported by setting *ok to false, and success by setting *ok to true.

This function ignores leading and trailing whitespace.

See also toShort() and toString().

QString QLocale::toUpper(const QString & str) const

Returns an uppercase copy of str.

This function was introduced in Qt 4.8.

QStringList QLocale::uiLanguages() const

Returns an ordered list of locale names for translation purposes in preference order.

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 object to the QTranslator::load() function.

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

This function was introduced in Qt 4.8.

See also QTranslator and bcp47Name().

QList<Qt::DayOfWeek> QLocale::weekdays() const

Returns a list of days that are considered weekdays according to the current locale.

This function was introduced in Qt 4.8.

QChar QLocale::zeroDigit() const

Returns the zero digit character of this locale.

This function was introduced in Qt 4.1.

bool QLocale::operator!=(const QLocale & other) const

Returns true if the QLocale object is not the same as the other locale specified; otherwise returns false.

QLocale & QLocale::operator=(const QLocale & other)

Assigns other to this QLocale object and returns a reference to this QLocale object.

bool QLocale::operator==(const QLocale & other) const

Returns true if the QLocale object is the same as the other locale specified; otherwise returns false.
