setGlobalPreferencesForLocale Sets the locale settings based on the given locale name.

Parameters

localeName

The locale name. Note this sets only the language and country, not the script or other settings. Even if the string violates the locale format, the string may be saved to the preferences anyway.

        const QStringList countryAndMaybeCodesetOrModifier{parts[2].split(".")};
        assert(countryAndMaybeCodesetOrModifier.length() > 0 && countryAndMaybeCodesetOrModifier.length() <= 3);

        if(countryAndMaybeCodesetOrModifier.length() > 0) {
            prefs.setCountryIsoCode(countryAndMaybeCodesetOrModifier[0].toStdString());
        }
        return;
    }
}

void geometrize::setTranslatorsForLocale

(

const QString &

locale

)

installTranslatorsForLocale Installs translators for the application.

Parameters

locale

A string in the form language_country. Note this is not threadsafe.

{
    QCoreApplication* application{QCoreApplication::instance()};
    if(application == nullptr) {
        assert(0 && "Attempting to set application translator before app is created");
        return;
    }

    // Remove and destroy old translators
    purgeTranslators(application);

    // Install the new translators
    const auto loadAndAddTranslator = [&application](const QString& file, const QString& directory) {
        QTranslator* translator{new QTranslator()};
        translator->load(file, directory);
