QTranslator检查

Question

How to check which file with translation was loaded ? (Current loaded translation) I load translation in main.c and I would like to check in MainWindow Class which translation was loaded.

Answer 1

I don't think you can do it, using Qt's methods.

The best way of doing it would be to write a wrapper around QTranslator and store all loaded translation files in it (you can load more than one translation file at a time).

Much worse, but easier way is to use a fake translation. Something like this:

const QString check = tr("lang");
if (check == "en") {
    // it's english
} else if (check == "fr") {
    // it's french
}
...

According to Internationalization with Qt , you anyway get the system locale to load the appropriate translation file. Just check the value of the locale string:

#include <QLocale>

QString locale = QLocale::system().name();

For example, for English, it is "en", for German - "de".
