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.

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 is constructed with the default constructor it will use the default locale settings
QString8::toInteger(), QString::toDouble(), etc., interpret the string according to the default locale, if this fails these methods use the "C" locale
QString8::formatArg() uses the default locale to format a number when its position specifier in the format string contains an 'L'

Using QLocale

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

When the language/country pair is found the matching locale is used
When the language is found but the country is not the language is used with the most appropriate available country
If neither the language nor the country are found the default locale is used

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

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").formatArg(12345).formatArg(12345).formatArg(12345, 0, 16);    // str == "12345 12,345 3039"

An alternative method for constructing a QLocale object is by specifying the locale name. The following constructor converts the locale name to a language/country pair, it does not use the system locale database.

QLocale korean("ko");

QLocale swiss("de_CH");

enum QLocale::CurrencySymbolFormat

Specifies the format of the currency symbol.

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

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`	Long version of day and month names ("January" or "February")
`QLocale::ShortFormat`	`1`	Short version of day and month names ("Jan" or "Feb")
`QLocale::NarrowFormat`	`2`	Special version of day and month names for use when space is limited; for example, returning "J" as a month name. The narrow format might contain the same text for different months and days or it can even be an empty string if the locale does not support narrow names, so you should avoid using it for date formatting. Also, for the system locale this format is the same as ShortFormat.

Constructor & Destructor 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 using the format shown below.

The underscore can be replaced by a minus sign

If the format is invalid or the language is not a valid ISO 639 code, the "C" locale will be used

If country is missing or is not a valid ISO 3166 code, the most appropriate country is chosen for the specified language

Another option is to pass "C" for the name

"language[_script][_country][.codeset][\@modifier]"

Language: Two letter ISO 639 language code in lowercase
Script: Four letter ISO 15924 script code in titlecase
Country: Two or three letter ISO 3166 country code in uppercase
Codeset: Ignored
Modifier: Ignored

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

See also: bcp47Name()

QLocale::QLocale	(	Language	language,
		Country	country
	)

Constructs a QLocale object with the specified language and country. The language and country that are actually used can be queried using language() and country().

See also: setDefault(), language(), country()

QLocale::QLocale	(	Language	language,
		Script	script = `Script::AnyScript`,
		Country	country = `Country::AnyCountry`
	)

Constructs a QLocale object with the specified language, script and country. The language, script and country that are actually used can be queried using language(), script() and country().

See also: setDefault(), language(), script(), country()

QLocale::QLocale ( const QLocale & other )

Copy constructs a new QLocale from other.

QLocale::QLocale ( QLocale && other )

Move constructs a new QLocale from other.

Method Documentation

QString QLocale::amText ( ) const

Returns the localized name of the "AM" suffix for times specified using the conventions of the 12-hour clock.

See also: pmText()

QString QLocale::bcp47Name ( ) const

Returns the dash-separated language, script and country (and possibly other BCP47 fields) of this locale as a string. Unlike the uiLanguages() the returned value of the bcp47Name() represents the locale name of the QLocale data but not the language the user-interface should be in.

This method tries to conform the locale name to BCP47.

See also: language(), country(), script(), uiLanguages()

QLocale QLocale::c ( )

inlinestatic

Returns a QLocale object initialized to the "C" locale.

This locale is similar to using English for the language and UnitedStates for the Country, which would be "en_US". The main difference is with "C" the number and date formatting are simplified and the sort order is case sensitive.

See also: system()

Country QLocale::country ( ) const

Returns the country of this QLocale.

See also: language(), script(), countryToString(), bcp47Name()

QString QLocale::countryToString ( Country country )

static

Returns a QString containing the name of country.

See also: languageToString(), scriptToString(), country(), bcp47Name()

QString QLocale::createSeparatedList ( const QStringList & list ) const

Returns a string that represents a join of a given list of strings with a separator defined by the QLocale.

QString QLocale::currencySymbol ( CurrencySymbolFormat symbolFormat = CurrencySymbol ) const

Returns a currency symbol according to the symbolFormat.

QString QLocale::dateFormat ( FormatType formatType = LongFormat ) const

Returns the date format used for the current locale. If formatType is LongFormat the format will be a long version. Otherwise it uses a shorter version.

See also: QDate::toString(), QDate::fromString()

QString QLocale::dateTimeFormat ( FormatType formatType = LongFormat ) const

Returns the date time format used for the current locale. If formatType is ShortFormat the format will be a short version, otherwise uses a longer version.

See also: QDateTime::toString(), QDateTime::fromString()

QString QLocale::dayName	(	int	day,
		FormatType	formatType = `LongFormat`
	)		const

Returns the localized name of the day (where 1 represents Monday, 2 represents Tuesday and so on), in the format specified by formatType.

See also: monthName(), standaloneDayName()

QChar QLocale::decimalPoint ( ) const

Returns the decimal point character of this QLocale.

QChar QLocale::exponential ( ) const

Returns the exponential character of this QLocale.

Qt::DayOfWeek QLocale::firstDayOfWeek ( ) const

Returns the first day of the week according to this QLocale.

QChar QLocale::groupSeparator ( ) const

Returns the group separator character of this QLocale.

Language QLocale::language ( ) const

Returns the language of this QLocale.

See also: script(), country(), languageToString(), bcp47Name()

QString QLocale::languageToString ( Language language )

static

Returns a QString containing the name of language.

See also: countryToString(), scriptToString(), bcp47Name()

QList< QLocale > QLocale::matchingLocales	(	QLocale::Language	language,
		QLocale::Script	script,
		QLocale::Country	country
	)

static

Returns a list of valid locales which match the given language, script, and country.

// returns a list of every locale
QList<QLocale> list = QLocale::matchingLocales(QLocale::AnyLanguage, QLocale::AnyScript, QLocale::AnyCountry);
 
// returns a list of every locale for Switzerland
QList<QLocale> list = QLocale::matchingLocales(QLocale::AnyLanguage, QLocale::AnyScript, QLocale::Switzerland);

MeasurementSystem QLocale::measurementSystem ( ) const

Returns the measurement system for the locale.

QString QLocale::monthName	(	int	month,
		FormatType	formatType = `LongFormat`
	)		const

Returns the localized name of month, in the format specified by formatType.

See also: dayName(), standaloneMonthName()

QString QLocale::name ( ) const

Returns the language and country of this QLocale 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 or three-letter ISO 3166 country code.

If QLocale object was constructed with an explicit script, name() will not contain it for compatibility reasons. Use bcp47Name() instead if you need a full locale name.

See also: QLocale(), language(), script(), country(), bcp47Name()

QString QLocale::nativeCountryName ( ) const

Returns a native name of the country for the locale. For example "España" for Spanish/Spain locale.

double QLocale::toDouble	(	const QString &	s,
		bool *	ok = `nullptr`
	)		const

Returns the double represented by the localized string s. Unlike QString::toDouble() this method does not fall back to the "C" locale if the string can not be interpreted in this locale. Leading and trailing whitespace is ignored.

If the conversion fails 0.0 is returned. If ok is not a nullptr, this method will set the value according to the success of the conversion. The value is false to indicate the conversion failed, otherwise ok is set to true.

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

In the last conversion the return value is 1234.0 because '.' is the thousands group separator in the German locale.
