Detailed Description

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()).
