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.
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 QInputMethod::locale().
QLocale's data is based on Common Locale Data Repository v34.
See also QString::arg(), QString::toInt(), QString::toDouble(), and QInputMethod::locale().

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::DataSizeFormat
flags QLocale::DataSizeFormats
Specifies the format for representation of data quantities.
| Constant | Value | Description |
|---|---|---|
QLocale::DataSizeIecFormat | 0 | format using base 1024 and IEC prefixes: KiB, MiB, GiB, ... |
QLocale::DataSizeTraditionalFormat | DataSizeSIQuantifiers | format using base 1024 and SI prefixes: kB, MB, GB, ... |
QLocale::DataSizeSIFormat | DataSizeBase1000 | DataSizeSIQuantifiers | format using base 1000 and SI prefixes: kB, MB, GB, ... |
This enum was introduced or modified in Qt 5.10.
The DataSizeFormats type is a typedef for QFlags<DataSizeFormat>. It stores an OR combination of DataSizeFormat values.
See also formattedDataSize().
enum QLocale::FloatingPointPrecisionOption
This enum defines constants that can be given as precision to QString::number(), QByteArray::number(), and QLocale::toString() when converting floats or doubles, in order to express a variable number of digits as precision.
| Constant | Value | Description |
|---|---|---|
QLocale::FloatingPointShortest | -128 | The conversion algorithm will try to find the shortest accurate representation for the given number. "Accurate" means that you get the exact same number back from an inverse conversion on the generated string representation. |
This enum was introduced or modified in Qt 5.7.
See also toString(), QString, and QByteArray.
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. |
See also QDateTime::toString(), QDate::toString(), and QTime::toString().
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. |

This enum was introduced or modified in Qt 4.4.
enum QLocale::NumberOption
flags QLocale::NumberOptions
This enum defines a set of options for number-to-string and string-to-number conversions. They can be retrieved with numberOptions() and set with setNumberOptions().
| Constant | Value | Description |
|---|---|---|
QLocale::DefaultNumberOptions | 0x0 | This option represents the default behavior, with group separators, with one leading zero in single digit exponents, and without trailing zeroes after the decimal dot. |
QLocale::OmitGroupSeparator | 0x01 | If this option is set, the number-to-string functions will not insert group separators in their return values. The default is to insert group separators. |
QLocale::RejectGroupSeparator | 0x02 | If this option is set, the string-to-number functions will fail if they encounter group separators in their input. The default is to accept numbers containing correctly placed group separators. |
QLocale::OmitLeadingZeroInExponent | 0x04 | If this option is set, the number-to-string functions will not pad exponents with zeroes when printing floating point numbers in scientific notation. The default is to add one leading zero to single digit exponents. |
QLocale::RejectLeadingZeroInExponent | 0x08 | If this option is set, the string-to-number functions will fail if they encounter an exponent padded with zeroes when parsing a floating point number in scientific notation. The default is to accept such padding. |
QLocale::IncludeTrailingZeroesAfterDot | 0x10 | If this option is set, the number-to-string functions will pad numbers with zeroes to the requested precision in "g" or "most concise" mode, even if the number of significant digits is lower than the requested precision. The default is to omit trailing zeroes. |
QLocale::RejectTrailingZeroesAfterDot | 0x20 | If this option is set, the string-to-number functions will fail if they encounter trailing zeroes after the decimal dot when parsing a number in scientific or decimal representation. The default is to accept trailing zeroes. |
The NumberOptions type is a typedef for QFlags<NumberOption>. It stores an OR combination of NumberOption values.
See also setNumberOptions() and numberOptions().
enum QLocale::QuotationStyle
This enum defines a set of possible styles for locale specific quotation.
| Constant | Value | Description |

Member Function Documentation
QString QLocale::toCurrencyString(float value, const QString &symbol = QString()) const
QString QLocale::toCurrencyString(float i, const QString &symbol, int precision) const
This function overloads toCurrencyString().
QLocale::QLocale()
Constructs a 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().
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 (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).
See also bcp47Name().
QLocale::QLocale(QLocale::Language language, QLocale::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(QLocale::Language language, QLocale::Script script, QLocale::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().

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 function tries to conform the locale name to BCP47.
This function was introduced in Qt 4.8.
See also language(), country(), script(), and uiLanguages().

QString QLocale::formattedDataSize(qint64 bytes, int precision = 2, QLocale::DataSizeFormats format = DataSizeIecFormat)
Converts a size in bytes to a human-readable localized string, comprising a number and a quantified unit. The quantifier is chosen such that the number is at least one, and as small as possible. For example if bytes is 16384, precision is 2, and format is DataSizeIecFormat (the default), this function returns "16.00 KiB"; for 1330409069609 bytes it returns "1.21 GiB"; and so on. If format is DataSizeIecFormat or DataSizeTraditionalFormat, the given number of bytes is divided by a power of 1024, with result less than 1024; for DataSizeSIFormat, it is divided by a power of 1000, with result less than 1000. DataSizeIecFormat uses the new IEC standard quantifiers Ki, Mi and so on, whereas DataSizeSIFormat uses the older SI quantifiers k, M, etc., and DataSizeTraditionalFormat abuses them.

QString QLocale::toUpper(const QString &str) const
Returns an uppercase copy of str.
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.
This function was introduced in Qt 4.8.
See also QString::toUpper().
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 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().
