Detailed Description

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

QLocale is constructed for a specified language, optional script and territory. It offers various facilities for formatting data as text, localized appropriately, and for reading data out of localized text.

Example:

egyptian = QLocale(QLocale.Arabic, QLocale.Egypt)
s1 = egyptian.toString(1.571429E+07, 'e')
s2 = egyptian.toString(10)
d = egyptian.toDouble(s1)
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.

  • arg() uses the default locale to format a number when its position specifier in the format string contains an ‘L’, e.g. “%L1”.

The following example illustrates how to use QLocale directly:

ok = bool()
d = float()
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.
str = QString("%1 %L2 %L3").arg(12345).arg(12345).arg(12345, 0, 16)
# str == "12345 12,345 3039"

An alternative method for constructing a QLocale object is by specifying the locale name.

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

This constructor reads the language, script and/or territory from the given name, accepting either uderscore or dash as separator (and ignoring any trailing .codeset or @variant suffix).

Note

For the current keyboard input locale take a look at QInputMethod::locale().

QLocale ‘s data is based on Common Locale Data Repository v45.

Matching combinations of language, script and territory

QLocale has data, derived from CLDR, for many combinations of language, script and territory, but not all. If it is constructed with all three of these key values specified (treating AnyLanguage, AnyScript or AnyTerritory as unspecified) and QLocale has data for the given combination, this data is used. Otherwise, QLocale does its best to find a sensible combination of language, script and territory, for which it does have data, that matches those that were specified.

The CLDR provides tables of likely combinations, which are used to fill in any unspecified key or keys; if QLocale has data for the result of such a likely combination, that is used. If no language is specified, and none can be determined from script and territory, or if QLocale has no data for the language, the “C” locale (when reading the keys from a string) or default locale (otherwise) is used.

When QLocale has no data for the keys specified, with likely keys filled in where unspecified, but does have data for the resulting language, a fall-back is sought, based on ignoring either territory, script or both (in that order). This results in a QLocale which may not match what was asked for, but provides localization that’s as suitable as the available data permits, for the keys specified.

Use language() , script() and territory() to determine the actual keys used.

Note

Use the Territory alias for this enumeration where possible. The Country enum shall be renamed to Territory at a later release.

class MeasurementSystem

This enum defines which units are used for measurement.

Constant

Description

QLocale.MetricSystem

This value indicates metric units, such as meters, centimeters and millimeters.

QLocale.ImperialUSSystem

This value indicates imperial units, such as inches and miles as they are used in the United States.

QLocale.ImperialUKSystem

This value indicates imperial units, such as inches and miles as they are used in the United Kingdom.

QLocale.ImperialSystem

Provided for compatibility. Same as ImperialUSSystem

class FormatType

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

Constant

Description

QLocale.LongFormat

Longer format.

QLocale.ShortFormat

Shorter format.

QLocale.NarrowFormat

A special version for use when space is very limited.

Note

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.

class NumberOption

(inherits enum.Flag) This enum defines a set of options for number-to-string and string-to-number conversions. They can be retrieved with numberOptions() and set with setNumberOptions() .

Constant

Description

QLocale.DefaultNumberOptions

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

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

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

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

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

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

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.

class FloatingPointPrecisionOption

(inherits enum.IntEnum) This enum defines a constant that can be given as precision to number() , number() , and toString() when converting floats or doubles, in order to express a variable number of digits as precision.

Constant

Description

QLocale.FloatingPointShortest

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).

toString() number() number()

class TagSeparator

Indicate how to combine the parts that make up a locale identifier.

A locale identifier may be made up of several tags, indicating language, script and territory (plus, potentially, other details), joined together to form the identifier. Various standards and conventional forms use either a dash (the Unicode HYPHEN-MINUS, U+002D) or an underscore (LOW LINE, U+005F). Different clients of QLocale may thus need one or the other.

Constant

Description

QLocale.TagSeparator.Dash

Use '-', the dash or hyphen character.

QLocale.TagSeparator.Underscore

Use '_', the underscore character.

Note

Although dash and underscore are the only separators used in public standards (as at 2023), it is possible to cast any ASCII character to this type if a non-standard ASCII separator is needed. Casting a non-ASCII character (with decimal value above 127) is not supported: such values are reserved for future use as enum members if some public standard ever uses a non-ASCII separator. It is, of course, possible to use replace() to replace the separator used by a function taking a parameter of this type with an arbitrary Unicode character or string.

Added in version 6.7.

class CurrencySymbolFormat

Specifies the format of the currency symbol.

Constant

Description

QLocale.CurrencyIsoCode

a ISO-4217 code of the currency.

QLocale.CurrencySymbol

a currency symbol.

QLocale.CurrencyDisplayName

a user readable name of the currency.

Added in version 4.8.

class DataSizeFormat

(inherits enum.Flag) Specifies the format for representation of data quantities.

Constant

Description

QLocale.DataSizeIecFormat

format using base 1024 and IEC prefixes: KiB, MiB, GiB, …

QLocale.DataSizeTraditionalFormat

format using base 1024 and SI prefixes: kB, MB, GB, …

QLocale.DataSizeSIFormat

format using base 1000 and SI prefixes: kB, MB, GB, …

class LanguageCodeType

(inherits enum.IntFlag) This enum defines language code types that can be used to restrict set of language codes considered by codeToLanguage and languageToCode.

Constant

Description

QLocale.ISO639Part1

ISO 639 Part 1 Alpha 2 code.

QLocale.ISO639Part2B

ISO 639 Part 2 bibliographic Alpha 3 code.

QLocale.ISO639Part2T

ISO 639 Part 2 terminological Alpha 3 code.

QLocale.ISO639Part3

ISO 639 Part 3 Alpha 3 code.

QLocale.LegacyLanguageCode

Codes that are not part of the above set, but that were supported by Qt in the past. This value can only be used by codeToLanguage() . It is ignored when passed to languageToCode() .

QLocale.ISO639Part2

Any ISO 639 Part 2 code.

QLocale.ISO639Alpha2

Any ISO-639 2-letter code.

QLocale.ISO639Alpha3

QLocale.AnyLanguageCode

Specifies that any code can be used.

Added in version 6.3.

class QuotationStyle

This enum defines a set of possible styles for locale specific quotation.

Constant

Description

QLocale.StandardQuotation

If this option is set, the standard quotation marks will be used to quote strings.

QLocale.AlternateQuotation

If this option is set, the alternate quotation marks will be used to quote strings.

See also

quoteString()

Added in version 4.8.

PySide6.QtCore.QLocale.DefaultTwoDigitBaseYear
__init__()

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() .

__init__(name)
Parameters:

name – str

Constructs a QLocale object with the specified 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).

See also

bcp47Name() Matching combinations of language, script and territory

__init__(other)
Parameters:

otherQLocale

Constructs a QLocale object as a copy of other.

__init__(name)
Parameters:

name – str

This is an overloaded function.

__init__(language, territory)
Parameters:

Constructs a QLocale object for the specified language and territory.

If there is more than one script in use for this combination, a likely script will be selected. If QLocale has no data for the specified language, the default locale is used. If QLocale has no data for the specified combination of language and territory, an alternative territory may be used instead.

See also

setDefault() Matching combinations of language, script and territory

__init__(language[, script=QLocale.Script.AnyScript[, territory=QLocale.Country.AnyTerritory]])
Parameters:

Constructs a QLocale object for the specified language, script and territory.

If QLocale does not have data for the given combination, it will find data for as good a match as it can. It falls back on the default locale if

  • language is AnyLanguage and no language can be inferred from script and territory

  • QLocale has no data for the language, either given as language or inferred as above.

See also

setDefault() Matching combinations of language, script and territory

amText()
Return type:

str

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

See also

pmText()

bcp47Name([separator=QLocale.TagSeparator.Dash])
Parameters:

separatorTagSeparator

Return type:

str

Returns the BCP47 field names joined with dashes.

This combines as many of language, script and territory (and possibly other BCP47 fields) for this locale as are needed to uniquely specify it. Note that fields may be omitted if the Unicode consortium’s Likely Subtag Rules imply the omitted fields when given those retained. See name() for how to construct a string from individual fields, if some other format is needed.

Unlike uiLanguages() , the value returned by bcp47Name() represents the locale name of the QLocale data; this need not be the language the user-interface should be in.

This function tries to conform the locale name to the IETF Best Common Practice 47, defined by RFC 5646. Since Qt 6.7, it supports an optional separator parameter which can be used to override the BCP47-specified use of a hyphen to separate the tags. For use in IETF-defined protocols, however, the default, Dash , should be retained.

static c()
Return type:

QLocale

Returns a 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).

system()

static codeToCountry(countryCode)
Parameters:

countryCode – str

Return type:

Country

Note

Parameters:

langLanguage

Return type:

.list of QLocale.Country

Note

This function is deprecated.

Returns a currency symbol according to the format.

dateFormat([format=QLocale.FormatType.LongFormat])
Parameters:

formatFormatType

Return type:

str

Returns the date format used for the current locale.

If format is LongFormat , the format will be elaborate, otherwise it will be short. For example, LongFormat for the en_US locale is dddd, MMMM d, yyyy, ShortFormat is M/d/yy.

dateTimeFormat([format=QLocale.FormatType.LongFormat])
Parameters:

formatFormatType

Return type:

str

Returns the date time format used for the current locale.

If format is LongFormat , the format will be elaborate, otherwise it will be short. For example, LongFormat for the en_US locale is dddd, MMMM d, yyyy h:mm:ss AP t, ShortFormat is M/d/yy h:mm AP.

dayName(arg__1[, format=QLocale.FormatType.LongFormat])
Parameters:
Return type:

str

Returns the localized name of the day (where 1 represents Monday, 2 represents Tuesday and so on), in the format specified by type.

For example, if the locale is en_US and day is 1, LongFormat will return Monday, ShortFormat Mon, and NarrowFormat M.

decimalPoint()
Return type:

str

Returns the fractional part separator for this locale.

This is the token that separates the whole number part from the fracional part in the representation of a number which has a fractional part. This is commonly called the “decimal point character” - even though, in many locales, it is not a “point” (or similar dot). It is (since Qt 6.0) returned as a string in case some locale needs more than one UTF-16 code-point to represent its separator.

exponential()
Return type:

str

Returns the exponent separator for this locale.

This is a token used to separate mantissa from exponent in some floating-point numeric representations. It is (since Qt 6.0) returned as a string because, in some locales, it is not a single character - for example, it may consist of a multiplication sign and a representation of the “ten to the power” operator.

DayOfWeek

Returns the first day of the week according to the current locale.

formattedDataSize(bytes[, precision=2[, format=QLocale.DataSizeFormat.DataSizeIecFormat]])
Parameters:
  • bytes – int

  • precision – int

  • format – Combination of DataSizeFormat

Return type:

str

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.

groupSeparator()
Return type:

str

Returns the digit-grouping separator for this locale.

This is a token used to break up long sequences of digits, in the representation of a number, to make it easier to read. In some locales it may be empty, indicating that digits should not be broken up into groups in this way. In others it may be a spacing character. It is (since Qt 6.0) returned as a string in case some locale needs more than one UTF-16 code-point to represent its separator.

language()
Return type:

Language

Returns the language of this locale.

static languageToCode(language[, codeTypes=QLocale.LanguageCodeType.AnyLanguageCode])
Parameters:
Return type:

str

Returns the two- or three-letter language code for language, as defined in the ISO 639 standards.

If specified, codeTypes selects which set of codes to consider. The first code from the set that is defined for language is returned. Otherwise, all ISO-639 codes are considered. The codes are considered in the following order: ISO639Part1, ISO639Part2B, ISO639Part2T, ISO639Part3. LegacyLanguageCode is ignored by this function.

Note

For QLocale::C the function returns "C". For QLocale::AnyLanguage an empty string is returned. If the language has no code in any selected code set, an empty string is returned.

Parameters:

languageLanguage

Return type:

str

Returns a QString containing the name of language.

static matchingLocales(language, script, territory)
Parameters:
Return type:

.list of QLocale

Returns the measurement system for the locale.

monthName(arg__1[, format=QLocale.FormatType.LongFormat])
Parameters:
Return type:

str

name([separator=QLocale.TagSeparator.Underscore])
Parameters:

separatorTagSeparator

Return type:

str

The short name of this locale.

Returns the language and territory of this locale as a string of the form “language_territory”, where language is a lowercase, two-letter ISO 639 language code, and territory is an uppercase, two- or three-letter ISO 3166 territory code. If the locale has no specified territory, only the language name is returned. Since Qt 6.7 an optional separator parameter can be supplied to override the default underscore character separating the two tags.

Even if the QLocale object was constructed with an explicit script, name() will not contain it for compatibility reasons. Use bcp47Name() instead if you need a full locale name, or construct the string you want to identify a locale by from those returned by passing its language() to languageToCode() and similar for the script and territory.

nativeCountryName()
Return type:

str

Note

This function is deprecated.

Use nativeTerritoryName() instead.

Returns a native name of the territory for the locale. For example “España” for Spanish/Spain locale.

Return type:

str

Returns a native name of the language for the locale. For example “Schweizer Hochdeutsch” for the Swiss-German locale.

nativeTerritoryName()
Return type:

str

Returns a native name of the territory for the locale. For example “España” for Spanish/Spain locale.

negativeSign()
Return type:

str

Returns the negative sign indicator of this locale.

This is a token presumed to be used as a prefix to a number to indicate that it is negative. It is (since Qt 6.0) returned as a string because, in some locales, it is not a single character - for example, because it includes a text-direction-control character.

numberOptions()
Return type:

Combination of NumberOption

Returns the options related to number conversions for this QLocale instance.

By default, no options are set for the standard locales, except for the “C” locale, which has OmitGroupSeparator set by default.

__ne__(rhs)

Sets the options related to number conversions for this QLocale instance.

standaloneDayName(arg__1[, format=QLocale.FormatType.LongFormat])
Parameters:
Return type:

str

Returns the localized name of the day (where 1 represents Monday, 2 represents Tuesday and so on) that is used as a standalone text, in the format specified by type.

Parameters:
Return type:

str

Returns the localized name of month that is used as a standalone text, in the format specified by type.

swap(other)
Parameters:

otherQLocale

Swaps locale other with this locale. This operation is very fast and never fails.

static system()
Return type:

QLocale

Returns a QLocale object initialized to the system locale.

The system locale may use system-specific sources for locale data, where available, otherwise falling back on QLocale’s built-in database entry for the language, script and territory the system reports.

For example, on Windows, this locale will use the decimal/grouping characters and date/time formats specified in the system configuration panel.

Note

Qt for Python on macOS will not reflect the user’s region and language preferences though QLocale::system(), but will instead reflect the environment variables POSIX uses to specify locale, similar to Python’s locale module. If the system locale cannot be determined, which can be due to none of the variables ‘LC_ALL’, ‘LC_CTYPE’, ‘LANG’ or ‘LANGUAGE’ being set by your environment, then the default POSIX locale or ‘C’ locale is returned.

See also c().

  • baseYear – int

Return type:

QDate

Reads string as a date in a locale-specific format.

Parses string and returns the date it represents. The format of the date string is chosen according to the format parameter (see dateFormat() ).

Some locales use, particularly for ShortFormat , only the last two digits of the year. In such a case, the 100 years starting at baseYear are the candidates first considered. Prior to 6.7 there was no baseYear parameter and 1900 was always used. This is the default for baseYear, selecting a year from then to 1999. In some cases, other fields may lead to the next or previous century being selected, to get a result consistent with all fields given. See fromString() for details.

Note

Month and day names, where used, must be given in the locale’s language.

If the date could not be parsed, returns an invalid date.

If the string can be parsed and represents an invalid date-time (e.g. in a gap skipped by a time-zone transition), an invalid QDateTime is returned, whose toMSecsSinceEpoch() represents a near-by date-time that is valid. Passing that to fromMSecsSinceEpoch() will produce a valid date-time that isn’t faithfully represented by the string parsed.

toDateTime(string, format, cal[, baseYear=1900])
Parameters:
Return type:

QDateTime

This is an overloaded function.

toDateTime(string, format, cal[, baseYear=1900])
Parameters:
  • string – str

  • format – str

  • calQCalendar

  • baseYear – int

Return type:

QDateTime

This is an overloaded function.

toDouble(s)
Parameters:

s – str

Return type:

(float, bool ok)

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Returns the double represented by the localized string s.

Returns an infinity if the conversion overflows or 0.0 if the conversion fails for any other reason (e.g. underflow).

If ok is not None, failure is reported by setting *``ok`` to false, and success by setting *``ok`` to true.

ok = bool()
d = float()
c = QLocale(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, d == 0
german = QLocale(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 == 0
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.

If ok is not None, failure is reported by setting *``ok`` to false, and success by setting *``ok`` to true.

This function ignores leading and trailing whitespace.

toInt(s)
Parameters:

s – str

Return type:

(int, bool ok)

Returns the int represented by the localized string s.

If the conversion fails the function returns 0.

If ok is not None, failure is reported by setting *``ok`` to false, and success by setting *``ok`` to true.

This function ignores leading and trailing whitespace.

toString(f[, format='g'[, precision=6]])
Parameters:
  • f – float

  • format – int

  • precision – int

Return type:

str

This is an overloaded function.

Returns a string representing the floating-point number f.

The form of the representation is controlled by the format and precision parameters.

The format defaults to 'g'. It can be any of the following:

Format

Meaning

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'

same as 'f' except for INF and NAN (see below)

'g'

use 'e' or 'f' format, whichever is more concise

maximum number of significant digits (trailing zeroes are omitted)

'G'

use 'E' or 'F' format, whichever is more concise

The special precision value 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.

For the '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.

toString(f[, format='g'[, precision=6]])
Parameters:
  • f – float

  • format – int

  • precision – int

Return type:

str

This is an overloaded function.

Returns a string representing the floating-point number f.

The format and precision have the same meanings as described in toString(double, char, int) .

toTime(string[, format=QLocale.FormatType.LongFormat])
Parameters:
Return type:

QTime

Reads string as a time in a locale-specific format.

Parses string and returns the time it represents. The format of the time string is chosen according to the format parameter (see timeFormat() ).

Note

Any am/pm indicators used must match amText() or pmText() , ignoring case.

If the time could not be parsed, returns an invalid time.

toTime(string, format)
Parameters:
  • string – str

  • format – str

Return type:

QTime

Reads string as a time in the given format.

Parses string and returns the time it represents. See fromString() for the interpretation of format.

Note

Any am/pm indicators used must match amText() or pmText() , ignoring case.

If the time could not be parsed, returns an invalid time.

toUInt(s)
Parameters:

s – str

Return type:

(int, bool ok)

toUpper(str)
Parameters:

str – str

Return type:

str

Returns an uppercase copy of str.

If Qt Core is using the ICU libraries, they will be used to perform the transformation according to the rules of the current locale. Otherwise the conversion may be done in a platform-dependent manner, with toUpper() as a generic fallback.

Note

In some cases the uppercase form of a string may be longer than the original.

toUpper()

uiLanguages([separator=QLocale.TagSeparator.Dash])
Parameters:

separatorTagSeparator

Return type:

list of strings

List of locale names for use in selecting translations

Each entry in the returned list is the name of a locale suitable to the user’s preferences for what to translate the UI into. Where a name in the list is composed of several tags, they are joined as indicated by separator. Prior to Qt 6.7 a dash was used as separator.

For example, using the default separator Dash , if the user has configured their system to use English as used in the USA, the list would be “en-Latn-US”, “en-US”, “en”. The order of entries is the order in which to check for translations; earlier items in the list are to be preferred over later ones. If your translation files use underscores, rather than dashes, to separate locale tags, pass Underscore as separator.

Most likely you do not need to use this function directly, but just pass the QLocale object to the load() function.

weekdays()
Return type:

.list of Qt.DayOfWeek

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

zeroDigit()
Return type:

str

Returns the zero digit character of this locale.

This is a single Unicode character but may be encoded as a surrogate pair, so is (since Qt 6.0) returned as a string. In most locales, other digits follow it in Unicode ordering - however, some number systems, notably those using U+3007 as zero, do not have contiguous digits. Use toString() to obtain suitable representations of numbers, rather than trying to construct them from this zero digit.
