详细描述

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 .

范例:

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".

以下范例阐明如何直接使用 QLocale:

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 == 0
d = QString("1234.56").toDouble(&ok);   // ok == true,  d == 1234.56
QLocale::setDefault(QLocale::German);
d = QString("1234,56").toDouble(&ok);   // ok == false, d == 0
d = QString("1234.56").toDouble(&ok);   // ok == true,  d == 1234.56
QLocale::setDefault(QLocale(QLocale::English, QLocale::UnitedStates));
QString 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 ()).

使用 language () 和 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.

注意: 对于当前键盘输入区域设置,请查看 QInputMethod::locale ().

QLocale's data is based on Common Locale Data Repository v39.

The DataSizeFormats type is a typedef for QFlags <DataSizeFormat>. It stores an OR combination of DataSizeFormat values.

另请参阅 formattedDataSize ().

[since 5.7] enum QLocale:: FloatingPointPrecisionOption

This enum defines constants that can be given as precision to QString::number (), QByteArray::number (),和 QLocale::toString () when converting floats or doubles, in order to express a variable number of digits as precision.

常量 描述
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.

该枚举在 Qt 5.7 引入或被修改。

另请参阅 toString (), QString ,和 QByteArray .

enum QLocale:: FormatType

This enum describes the different formats that can be used when converting QDate , QTime ,和 QDateTime objects, as well as months and days, to strings specific to the locale.

常量 描述
QLocale::LongFormat 0 Longer format.
QLocale::ShortFormat 1 Shorter format.
QLocale::NarrowFormat 2 A special version for use when space is very limited.

注意: NarrowFormat might contain the same text for different months and days. 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 .

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 () 和设置采用 setNumberOptions ().

常量 描述
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.

成员函数文档编制

QLocale:: QLocale (const QLocale & other )

Constructs a QLocale object as a copy of other .

QLocale:: QLocale ( QLocale::Language language , QLocale::Script script , QLocale::Country country )

构造 QLocale 对象采用指定 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 () 和 country ().

另请参阅 setDefault (), language (), script (),和 country ().

QLocale:: QLocale ( QLocale::Language language , QLocale::Country country = AnyCountry)

构造 QLocale 对象采用指定 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 () 和 country ().

另请参阅 setDefault (), language (),和 country ().

QLocale:: QLocale (const QString & name )

构造 QLocale 对象采用指定 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 '_' (U+005F, "low line") or a dash '-' (U+002D, "hyphen-minus").

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).

另请参阅 bcp47Name ().

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 ().

另请参阅 setDefault ().

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

赋值 other 到此 QLocale object and returns a reference to this QLocale 对象。

QLocale:: ~QLocale ()

Destructor

QString QLocale:: amText () const

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

另请参阅 pmText ().

QString QLocale:: bcp47Name () const

Returns the dash-separated language, script and country (and possibly other BCP47 fields) of this locale as a string.

不像 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.

另请参阅 language (), country (), script (),和 uiLanguages ().

[static] QLocale QLocale:: c ()

返回 QLocale object initialized to the "C" locale.

This locale is based on en_US but with various quirks of its own, such as simplified number formatting and its own date formatting. It implements the POSIX standards that describe the behavior of standard library functions of the "C" programming language.

Among other things, this means its collation order is based on the ASCII values of letters, so that (for case-sensitive sorting) all upper-case letters sort before any lower-case one (rather than each letter's upper- and lower-case forms sorting adjacent to one another, before the next letter's two forms).

另请参阅 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 () 函数。

The first item in the list is the most preferred one.

QList < Qt::DayOfWeek > QLocale:: weekdays () const

Returns a list of days that are considered weekdays according to the current locale.

QString QLocale:: zeroDigit () const

返回此区域设置的 0 数字字符。

bool operator!= (const QLocale & lhs , const QLocale & rhs )

返回 true 若两 QLocale 对象, lhs and rhs 不同;否则返回 false .

注意: 系统区域设置不等于 QLocale 对象构造从其 language (), script () 和 country (), even if the two agree in all data fields. Nor are two locales with different number options equal.
