I'm not sure I'm following the question, but this is how you switch translation language in Qt:

#include <QDebug>
#include <QCoreApplication>
#include <QApplication>
#include <QTranslator>
#include <QSpinBox>
#include <QLibraryInfo>

int
main (int argc,
      char **argv)
{
    QTranslator translator;
    QApplication app( argc, argv );

    if (!translator.load("qt_uk", QLibraryInfo::location(QLibraryInfo::TranslationsPath))) {
        qDebug("Cannot load file");
    }
    app.installTranslator(&translator);

    qDebug() << QSpinBox::tr("More");

    if (!translator.load("qt_ru", QLibraryInfo::location(QLibraryInfo::TranslationsPath))) {
        qDebug("Cannot load file");
    }

    qDebug() << QSpinBox::tr("More");

    if (!translator.load("qt_es", QLibraryInfo::location(QLibraryInfo::TranslationsPath))) {
        qDebug("Cannot load file");
    }

    qDebug() << QSpinBox::tr("More");
}

Note you need libqt4-core-translations to be installed.
