The doc doesn't mention the LANGUAGE var. QLocale::QLocale() 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(). See also setDefault(). void QLocale::setDefault(const QLocale &locale) Sets the global default locale to locale. These values are used when a QLocale object is constructed with no arguments. If this function is not called, the system's locale is used. Warning: In a multithreaded application, the default locale should be set at application startup, before any non-GUI threads are created. Warning: This function is not reentrant. See also system() and c().
