详细描述

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 .

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 ()。设置默认区域设置有下列影响：

• 若 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 () 使用默认区域设置格式化数字，当它在格式化字符串中的位置说明符包含 L 时 (如：%L1)。

The following example illustrates how to use QLocale 直接：

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 ()).

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 v35.1.

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	值	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 types of format that can be used when converting QDate and QTime objects to strings.

常量	值	描述
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.

QString QLocale:: toCurrencyString ( float value , const QString & symbol = QString()) const

QString QLocale:: toCurrencyString ( float i , const QString & symbol , int precision ) const

此函数重载 toCurrencyString ().

QLocale:: QLocale ()

构造 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 (const QString & name )

构造 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 语言 , 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 ( QLocale::Language 语言 , QLocale::Country country = AnyCountry)

构造 QLocale object with the specified 语言 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 ( QLocale::Language 语言 , QLocale::Script script , QLocale::Country country )

构造 QLocale object with the specified 语言 , 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),
• 若 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 ().

QString QLocale:: bcp47Name () const

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

[static] QLocale QLocale:: c ()

返回 QLocale 对象被初始化成 C 区域设置。

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).

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.
