Detailed Description

The QLocale class is used to format data based on a given language or country. The displayed formatting for fields like a calendar date, time, currency, and number separators can be set based on a given region of the world by calling methods in this class.

For example, the method currencySymbol() returns the appropriate string for the specified locale. In the United States the value will be "$" and in European countries which use the euro, the symbol will be "€".

In the following example the locale is set to the language of Arabic as used in Egypt. Various strings and numbers are formatted based on the rules of this region.

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 passed to 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 to specify 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");

Specifies the format of the currency symbol.

ConstantValueDescription
QLocale::CurrencyIsoCode0 ISO-4217 code of the currency
QLocale::CurrencySymbol1 Currency symbol
QLocale::CurrencyDisplayName2 User readable name of the currency

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

ConstantValueDescription
QLocale::LongFormat0 Long version of day and month names ("January" or "February")
QLocale::ShortFormat1 Short version of day and month names ("Jan" or "Feb")
QLocale::NarrowFormat2 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.

This enumerated type is used to specify a language.

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

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.

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.

float QLocale::toFloat ( const QString s,
bool *  ok = nullptr 
) const

Returns the float represented by the localized string s or 0.0. 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.

int QLocale::toInt ( const QString s,
bool *  ok = nullptr,
int  base = 0 
) const

Returns the int represented by the localized string s using the given base. If the value for base is 0 it will be determined 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. Leading and trailing whitespace is ignored.

If the conversion fails 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.

If the value for base is 0 it will be determined 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. Leading and trailing whitespace is ignored.

If the conversion fails 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.
