QT Internationalization of the use of Qtranslator general use of QT design software, more use of the default English (including menus, buttons, dialog boxes, etc.) display, and then use the international functional class according to specific occasions, the same software to achieve the functions of different languages. Class Qtranslator is a class that implements internationalization and is easy to use. A simple and outrageous example:

    Qsettings settings;
    QString language = Settings.value ("language"). toString ();
    
    Qtranslator Qttranslator;
    QString translationfile = ":/translations/qt_" + language + ". QM";
    Qttranslator.load (translationfile);
    App.installtranslator (&qttranslator);
