[править] Подробное описание
The QSystemLocale class can be used to finetune the system locale of the user.
Warning: This class is only useful in very rare cases. Usually QLocale offers all the functionality required for application development.
QSystemLocale allows to override the values provided by the system locale ( QLocale::system()).
See also QLocale.

| QSystemLocale::DateToStringLong | 14 | converts the QDate stored in the in variant to a QString using the long date format |
| QSystemLocale::DateToStringShort | 15 | converts the QDate stored in the in variant to a QString using the short date format |
| QSystemLocale::TimeToStringLong | 16 | converts the QTime stored in the in variant to a QString using the long time format |

[править] Описание функций-членов
[править] QSystemLocale::QSystemLocale ()
Constructs a QSystemLocale object. The constructor will automatically install this object as the system locale and remove any earlier installed system locales.
[править] QSystemLocale::~QSystemLocale () [virtual]
Deletes the object.
[править] QLocale QSystemLocale::fallbackLocale () const [virtual]
Returns a fallback locale, that will get used for everything that is not explicitly overridden by the system locale.
[править] QVariant QSystemLocale::query ( QueryType type, QVariant in ) const [virtual]
Performs a query of the given type in the system locale for customized values or conversion. If the method returns a null QVariant, the conversion of the fallbackLocale() will be used.
in is unused for some of the query types.
