Translations of QMessageBox not work in Qt5.3

Question

I\'m a fan of Qt and update it frequently, Qt5.1->5.2->5.3.

However, the tranalations of Standard buttons like \"Ok\" \"Cancel\" \"Save\" do not work anymore in Qt5.

Answer 1

Starting from Qt5.3 the qt_*.qm is divided into multiple files (qt*_*.qm) and now you have to copy qtbase_*.qm to translation directory and use together.

QString translationsPath(QLibraryInfo::location(QLibraryInfo::TranslationsPath));
QLocale locale = QLocale::system();

QTranslator qtTranslator;
if (qtTranslator.load(locale, "qt", "_", translationsPath))
    a.installTranslator(&qtTranslator);

QTranslator qtBaseTranslator;
if (qtBaseTranslator.load(locale, "qtbase", "_", translationsPath))
    a.installTranslator(&qtBaseTranslator);
