Changing locale in Qt

Question

I tried to change locale using QLocale and setDefault function but it seems that it doesn\'t work. Here is example of changing locale using C localization library and QLocal

Answer 1

QLocale::setDefault() does not change the system locale. It changes what QLocale object created with default constructor is.

Supposedly, system locale can only be changed via system control panel/preferences by the user. If you want to format something that is not in the system locale, you need to specifically do that with a locale object.

This code:

QLocale curLocale(QLocale("pl_PL"));
QLocale::setDefault(curLocale);
QDate date = QDate::currentDate();
QString dateString = QLocale().toString(date);
qDebug() << dateString;
qDebug() << QLocale().name();

Prints this:

"piątek, 9 listopada 2012" 
"pl_PL"
