How to display a QDate-month with a different locale than system?

Question

The function QDate::toString(const QString &format) allows to display the month name with MMM (e.g. 'Jan' to 'Dec') or MMMM (e.g. 'January' to 'December').

But this function uses the system locale from QLocale::system() (source code).

What is the easiest way to display a QDate with a month name, for a specific QLocale ?

Answer 1

You must use toString() method of QLocale instead of QDate.

QDate d =  QDate::currentDate();
QList<QLocale> locales {QLocale(QLocale::Spanish),
            QLocale(QLocale::English),
            QLocale(QLocale::Dutch),
            QLocale(QLocale::Japanese),
            QLocale(QLocale::French),
            QLocale(QLocale::Chinese)};

QString format = "dd MMMM yyyy";

for(const QLocale locale: locales){
    qDebug()<<locale.toString(d, format);

}

output:

"16 octubre 2017"
"16 October 2017"
"16 oktober 2017"
"16 10月 2017"
"16 octobre 2017"
"16 十月 2017"
