详细描述

QLocale 是为指定语言、可选脚本和地区构造的。它提供将数据格式化成文本、适当本地化及从本地化文本读取数据的各种设施。

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 支持默认区域设置概念，在应用程序启动时由系统区域设置确定。可以改变默认区域设置通过调用静态成员 setDefault ()。设置默认区域设置有下列影响：

若 QLocale 对象是采用默认构造函数构造的，将使用默认区域设置。
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)。

以下范例阐明如何直接使用 QLocale：

bool ok;
double d;
QLocale::setDefault(QLocale::C);      // uses '.' as a decimal point
QLocale cLocale;                      // default-constructed C locale
d = cLocale.toDouble("1234,56", &ok); // ok == false, d == 0
d = cLocale.toDouble("1234.56", &ok); // ok == true,  d == 1234.56
QLocale::setDefault(QLocale::German); // uses ',' as a decimal point
QLocale german;                       // default-constructed German locale
d = german.toDouble("1234,56", &ok);  // ok == true,  d == 1234.56
d = german.toDouble("1234.56", &ok);  // ok == false, d == 0
QLocale::setDefault(QLocale::English);
// Default locale now uses ',' as a group separator.
QString str = QString("%1 %L2 %L3").arg(12345).arg(12345).arg(12345, 0, 16);
// str == "12345 12,345 3039"

构造 QLocale 对象的替代方法是通过指定区域设置名称。

QLocale korean("ko");
QLocale swiss("de_CH");

此构造函数从给定名称读取语言、脚本和/或地区，接受下划线或破折号作为分隔符(并忽略任何结尾 .codeset or @variant 后缀)。

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

QLocale 的数据基于 CLDR (公共区域设置数据存储库)，第 42 版。

语言、脚本和地区的匹配组合

QLocale 针对语言、脚本和地区的很多组合 (但不是全部) 拥有派生自 CLDR (公共区域设置数据存储库) 的数据。若它是采用所有这些的 3 指定键值构造的 (视 AnyLanguage , AnyScript or AnyTerritory 为未指定) 且 QLocale 拥有针对给定组合的数据，则使用该数据。否则，QLocale 会尽力找出语言、脚本和地区的合理组合，为拥有如这些指定的匹配数据。

CLDR 提供可能的组合表，用于填充一个或多个任何未指定键；若 QLocale 拥有针对这种可能组合的数据结果，将使用它。若语言未指定，且无法从脚本和地区确定，或者若 QLocale 不拥有语言数据，则使用 C (当从字符串读取键时) 或默认区域设置 (否则)。

当 QLocale 不拥有如指定键的数据，在未指定的地方以可能的键填充，但拥有如结果语言的数据，则基于地区、脚本或两者 (按此次序) 的忽略寻址回退。这会导致 QLocale 可能不匹配要求，但将为指定键提供可用准许数据的合适本地化。

使用 language (), script () 和 territory () 以确定实际使用键。

另请参阅 QString::arg () 和 QInputMethod::locale ().

成员类型文档编制

enum QLocale:: Country

此枚举类型用于标识地区。

单独地区可能是一个国家的省，国家 (目前为止的最常见情况) 或更大地理实体，其中某些本地化细节是特定的。

enum QLocale:: FloatingPointPrecisionOption

This enum defines a constant 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. In particular, trailing zeros are omitted (from the mantissa, in exponent formats).

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

enum QLocale:: FormatType

此枚举描述可以使用的不同格式，当转换 QDate , QTime ，和 QDateTime objects, as well as months and days, to strings specific to the locale.

常量	值	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 .

另请参阅 dateFormat (), timeFormat (), dateTimeFormat (), monthName (), standaloneMonthName (), dayName (), standaloneDayName (), toDate (), toTime ()，和 toDateTime ().

QLocale:: QLocale ()

构造 QLocale 对象，初始化采用默认区域设置。

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 () 和 system ().

`[explicit]` QLocale:: QLocale (const QString & name )

这是重载函数。

`[explicit, since 6.3]` QLocale:: QLocale ( QStringView name )

构造 QLocale 对象采用指定 name .

The name has the format "language[_script][_territory][.codeset][@modifier]" or "C", where:

language is a lowercase, two-letter, ISO 639 language code (some three-letter codes are also recognized),
script is a capitalized, four-letter, ISO 15924 script code,
territory is an uppercase, two-letter, ISO 3166 territory code (some numeric codes are also recognized), and
codeset and modifier are ignored.

The separator can be either underscore '_' (U+005F, "low line") or a dash '-' (U+002D, "hyphen-minus"). If QLocale has no data for the specified combination of language, script, and territory, then it uses the most suitable match it can find instead. If the string violates the locale format, or no suitable data can be found for the specified keys, the "C" locale is used instead.

This constructor is much slower than QLocale(Language, Script, Territory) or QLocale(Language, Territory).

该函数在 Qt 6.3 引入。

另请参阅 bcp47Name () 和语言、脚本和地区的匹配组合 .

QLocale:: QLocale ( QLocale::Language 语言 , QLocale::Territory territory )

QString QLocale:: toString ( double f , char format = 'g', int precision = 6) const

这是重载函数。

Returns a string representing the floating-point number f .

The form of the representation is controlled by the format and precision 参数。

The format 默认为 'g' 。它可以是下列任一：

格式	含义	Meaning of precision
`'e'`	format as [-]9.9e[+\|-]999	number of digits after the decimal point
`'E'`	format as [-]9.9E[+\|-]999	"
`'f'`	format as [-]9.9	"
`'F'`	如同 `'f'` except for INF and NAN (see below)	"
`'g'`	使用 `'e'` or `'f'` format, whichever is more concise	maximum number of significant digits (trailing zeroes are omitted)
`'G'`	使用 `'E'` or `'F'` format, whichever is more concise	"

特殊 precision 值 QLocale::FloatingPointShortest selects the shortest representation that, when read as a number, gets back the original floating-point value. Aside from that, any negative precision is ignored in favor of the default, 6.

对于 'e' , 'f' and 'g' formats, positive infinity is represented as "inf", negative infinity as "-inf" and floating-point NaN (not-a-number) values are represented as "nan". For the 'E' , 'F' and 'G' formats, "INF" and "NAN" are used instead. This does not vary with locale.
