我尝试使用QLocale和setDefault函数更改语言环境,但似乎它不起作用.以下是使用C本地化库和QLocale更改语言环境的示例.对于C本地化库,似乎它可以工作,但对于QLocale,似乎忽略了setDefault函数调用.

QLocale curLocale(QLocale("pl_PL"));
QLocale::setDefault(curLocale);
QDate date = QDate::currentDate();
QString dateString = date.toString();
// prints "Fri Nov 9 2012" but that was not expected
std::cout << dateString.toStdString() << std::endl;
// prints "en_US", but shouldn't it be "pl_PL"?
std::cout << QLocale::system().name().toStdString() << std::endl;

std::setlocale(LC_ALL, "pl_PL");
// prints "pl_PL"
std::cout << std::setlocale(LC_ALL, 0) << std::endl;
std::time_t currentTime;
std::time(&currentTime);
std::tm* timeinfo = std::localtime(&currentTime);
char charArray[40];
std::strftime(charArray, 40, "%a %b %d %Y", timeinfo);
// prints "pi lis 09 2012" and that's cool
std::cout << charArray …
