## Detailed Description

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

It is initialized with a country/language pair in its constructor and offers number-to-string and string-to-number conversion functions simmilar 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 s2 = 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(). 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::toDouble() interprets 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".

        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()).

The "C" locale is identical to English/UnitedStates.

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.

All the methods in QLocale, with the exception of setDefault(), are reentrant.

## Member Function Documentation

### QLocale::QLocale ()

Constructs a QLocale object initialized with the default locale.

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.

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).

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

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.
- 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 ( const QLocale & other )

Constructs a QLocale object as a copy of other.

### QLocale QLocale::c ()`[static]`

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

See also system().

### Country QLocale::country () const

Returns the country of this locale.

See also QLocale().

### QString QLocale::countryToString ( Country country )`[static]`

Returns a QString containing the name of country.

### Language QLocale::language () const

Returns the language of this locale.

See also QLocale().

### QString QLocale::languageToString ( Language language )`[static]`

Returns a QString containing the name of language.

### QString QLocale::name () const

Returns the language and country of this locale 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 ISO 3166 country code.

See also QLocale().

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

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

### void QLocale::setDefault ( const QLocale & locale )`[static]`

Warning: This function is not reentrant.

Sets the global default locale to locale. These values are used when a QLocale object is constructed with no arguments. If this function is not called, the system's locale is used.

Warning: In a multithreaded application, the default locale should be set at application startup, before any non-GUI threads are created.

See also system() and c().

### QLocale QLocale::system ()`[static]`

Returns a QLocale object initialized to the system locale.

### 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.

            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.

This function ignores leading and trailing whitespace.

See also toString() and QString::toDouble().

### float QLocale::toFloat ( const QString & s, bool * ok = 0 ) const

Returns the float 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.

This function ignores leading and trailing whitespace.

See also toString().

### int QLocale::toInt ( const QString & s, bool * ok = 0 ) const

Returns the int represented by the localized string s, or 0 if the conversion failed.

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

This function ignores leading and trailing whitespace.

See also toString().

### Q_LONG QLocale::toLong ( const QString & s, bool * ok = 0 ) const

Returns the long int represented by the localized string s, or 0 if the conversion failed.

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

This function ignores leading and trailing whitespace.

See also toString().

### Q_LLONG QLocale::toLongLong ( const QString & s, bool * ok = 0 ) const

Returns the long long int represented by the localized string s, or 0 if the conversion failed.

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

This function ignores leading and trailing whitespace.
