The default locale can be changed by calling the + static member setDefault(). Setting the default locale has the + following effects: + + \list + \i If a QLocale object is constructed with the default constructor, + it will use the default locale's settings. + \i QString::toInt(), QString::toDouble(), etc., interpret the + string according to the default locale. If this fails, it + falls back on the "C" locale. + \i QString::arg() uses the default locale to format a number when + its position specifier in the format string contains an 'L', + e.g. "%L1". + \endlist + + The following example illustrates how to use QLocale directly: + + \snippet doc/src/snippets/code/src_corelib_tools_qlocale.cpp 1 + + When a language/country pair is specified in the constructor, one + of three things can happen: + + \list + \i If the language/country pair is found in the database, it is used. + \i If the language is found but the country is not, or if the country + is \c AnyCountry, the language is used with the most + appropriate available country (for example, Germany for German), + \i If neither the language nor the country are found, QLocale + defaults to the default locale (see setDefault()). + \endlist + + Use language() and country() to determine the actual language and + country values used. + + An alternative method for constructing a QLocale object is by + specifying the locale name. + + \snippet doc/src/snippets/code/src_corelib_tools_qlocale.cpp 2 + + This constructor converts the locale name to a language/country + pair; it does not use the system locale database. + + \note For the current keyboard input locale take a look at + QApplication::keyboardInputLocale(). + + QLocale's data is based on Common Locale Data Repository v1.8.1. + + The double-to-string and string-to-double conversion functions are + covered by the following licenses: + + \legalese + Copyright (c) 1991 by AT&T. + + Permission to use, copy, modify, and distribute this software for any + purpose without fee is hereby granted, provided that this entire notice + is included in all copies of any software which is or includes a copy + or modification of this software and in all copies of the supporting + documentation for such software. + + THIS SOFTWARE IS BEING PROVIDED "AS IS", WITHOUT ANY EXPRESS OR IMPLIED + WARRANTY.
