QLocale(3qt)
โจ NAME โจ
QLocale โ the lil icon that converts between numbers and their string representations in various languages ๐๐ฌ
That's the whole job bestie. Numbers in, cute localized strings out (and back again). No cap.
๐ฆ SYNOPSIS ๐ฆ
okay so before we get into it, one big heads-up: almost all the functions in this class are reentrant when Qt is built with thread support. The exception is setDefault(). So if you're threading, that one function is the odd one out โ it's giving main-character-only, single-file energy ๐

okay that's the whole map of the class bestie, we got the languages, we got the countries, we got the conversions ๐ฆ
to be continuedโฆ there's more of this page coming, so hold that thought ๐โจ
๐ DESCRIPTION ๐
Okay bestie, gather round, because QLocale is literally the moment. It's the class that converts between numbers and their string representations in various languages โ like, all of them. It is giving polyglot main character energy and we are obsessed. ๐โจ
You birth a QLocale with a country/language pair in its constructor, and then it hands you number-to-string and string-to-number conversion functions that are basically the same vibe as the ones hanging out 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 s2 = egyptian.toInt(s2);
QLocale also understands the concept of a default locale, which gets figured out from the system's locale settings at application startup. You can swap it out whenever by calling the static member setDefault(). And the default locale has these effects, no cap:
- If a
QLocaleobject is constructed with the default constructor, it will use the default locale's settings. ๐ซถ QString::toDouble()interprets the string according to the default locale. If that 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".
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"
So when you specify a language/country pair in the constructor, one of three things can happen:
- If the language/country pair is found in the database, it is used. Slay, straightforward.
- If the language is found but the country is not, or if the country is
AnyCountry, then the language is used with the most appropriate available country (for example, Germany for German). Close enough, bestie. ๐ - If neither the language nor the country are found,
QLocaledefaults to the default locale (seesetDefault()). Rip, but okay.
Fun fact: the "C" locale is identical to English/UnitedStates. Iconic crossover.
Wanna know which language and country values actually got used? Call language() and country(). Done. โ
There's also an alternative way to construct a QLocale object: just hand it 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. FYI.
And heads up: all the methods in QLocale, with the exception of setDefault(), are reentrant. ๐ง

โจ MEMBER FUNCTION DOCUMENTATION โจ
QLocale::QLocale ()
Constructs a QLocale object initialized with the default locale. ๐
See also: setDefault().
QLocale::QLocale ( const QString & name )
Constructs a QLocale object with the specified name, which has the format "language[_country][.codeset][@modifier]" or "C", where:
- language is a lowercase, two-letter, ISO 639 language code,
- territory is an uppercase, two-letter, ISO 3166 country code,
- and codeset and modifier are ignored. ๐
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 and country codes are converted to their respective Language and Country enums. After this conversion is performed the constructor behaves exactly like QLocale(Country, Language).
heads up bestie: this constructor is much slower than QLocale(Country, Language). ๐ญ
See also: name().
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. โจ
- 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,
QLocaledefaults to the default locale (seesetDefault()).
The language and country that are actually used can be queried using language() and country(). ๐ซถ

QLocale QLocale::system () [static]
Returns a QLocale object initialized to the system locale. ๐ฅ๏ธโจ
double QLocale::toDouble ( const QString & s, bool * ok = 0 ) const
Returns the double represented by the localized string s, or 0.0 if the conversion failed.
If ok is not 0, reports failure by setting *ok to false and success by setting *ok to true.
Unlike QString::toDouble(), this function does not fall back to the "C" locale if the string cannot be interpreted in this locale. ๐
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. sneaky little period ๐ญ
This function ignores leading and trailing whitespace.

that's the whole overload family, all seven of them showing up like it's a group chat roll call ๐
QString QLocale::toString ( float i, char f = 'g', int prec = 6 ) const
okay so bestie, this is an overloaded member function โ it's here for convenience and it behaves essentially like the function right above it. no cap. ๐ซถ
f and prec have the same meaning as in QString::number(double, char, int). periodt.
See also toDouble(). ๐
QString QLocale::toString ( double i, char f = 'g', int prec = 6 ) const
same vibe, another overloaded member function, provided for convenience. it behaves essentially like the above function. literally the same energy. โจ
f and prec have the same meaning as in QString::number(double, char, int). fr fr.
See also toDouble(). ๐
uint QLocale::toUInt ( const QString & s, bool * ok = 0 ) const
Returns the unsigned int represented by the localized string s, or 0 if the conversion failed. if it flops, you get a zero, bestie. ๐ญ
If ok is not 0, it reports failure by setting *ok to false and success by setting *ok to true. so you always know what's up. ๐
This function ignores leading and trailing whitespace. it's giving "i don't see that extra space, periodt." ๐
See also toString().
Q_ULONG QLocale::toULong ( const QString & s, bool * ok = 0 ) const
Returns the unsigned long int represented by the localized string s, or 0 if the conversion failed. no cap.
If ok is not 0, reports failure by setting *ok to false and success by setting *ok to true. ๐ซถ

Returns the unsigned long long int represented by the localized string s, or 0 if the conversion failed. big number energy. ๐ฅ
If ok is not 0, reports failure by setting *ok to false and success by setting *ok to true. slay.
This function ignores leading and trailing whitespace. yes bestie, it does not care about your spaces. โจ
See also toString().
ushort QLocale::toUShort ( const QString & s, bool * ok = 0 ) const
Returns the unsigned short int represented by the localized string s, or 0 if the conversion failed. short king behavior. ๐
