详细描述

The Locale object may only be created via the Qt.locale() function. It cannot be created directly.

The Qt.locale() function returns a JS Locale object representing the locale with the specified name, which has the format "language[_territory][.codeset][@modifier]" or "C".

Locale supports the concept of a default locale, which is determined from the system's locale settings at application startup. If no parameter is passed to Qt.locale() the default locale object is returned.

The Locale object provides a number of functions and properties providing data for the specified locale.

The Locale object may also be passed to the Date and Number toLocaleString() and fromLocaleString() methods in order to convert to/from strings using the specified locale.

This example shows the current date formatted for the German locale: 

import QtQuick 2.0
Text {
    text: "The date is: " + Date().toLocaleString(Qt.locale("de_DE"))
}

The following example displays the specified number in the correct format for the default locale: 

import QtQuick 2.0
Text {
    text: "The value is: " + Number(23443.34).toLocaleString(Qt.locale())
}

Qt Quick Locale's data is based on Common Locale Data Repository v1.8.1.

区域设置字符串格式类型

The monthName() , standaloneMonthName() , dayName() and standaloneDayName() can use the following enumeration values to specify the formatting of the string representation for a Date object.

  • Locale.LongFormat The long version of day and month names; for example, returning "January" as a month name.
  • Locale.ShortFormat The short version of day and month names; for example, returning "Jan" as a month name.
  • Locale.NarrowFormat 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.

Additionally the double-to-string and string-to-double conversion functions are covered by the following licenses:
