Testing automatic language sensing

[Jon Heron]

Hello all,
I should start off by stating I am a beginner programmer!
I have recently completed my Qt for Symbian app and deployed it to OVI and other various mobile stores.
I just got my first translation of my application completed in Spanish. Here are the steps I used to add the translation to the application;

1. Selected File->Release in the Qt liguist tool which created the "applicationName_es.qm" file.
2. Added "TRANSLATIONS = ApplicationName_es.ts" to the pro file.
3. Added

   QString locale = QLocale::system().name();
       QTranslator translator;
       translator.load(QString("ApplicationName_") + locale);
        a.installTranslator(&translator);

   QString locale = QLocale::system().name();
       QTranslator translator;
       translator.load(QString("ApplicationName_") + locale);
        a.installTranslator(&translator);

   To copy to clipboard, switch view to plain text mode 
   to main.

Now I would like to see if the translation works...
My version of Windows7 does not support language packs so I used the RDA to load the app on a symbian device, then switched the devices language to Spanish which I would assume should be now detected as ES and intern load the Spanish version of my app... Unfortunately it does not, only the English version is loaded....

How do I test if the translated version is working?
I have tried

translator.load("ApplicationName_es.qm");

translator.load("ApplicationName_es.qm");

To copy to clipboard, switch view to plain text mode 

and it still shows up in English?
Any and all help would be greatly appreciated!

Cheers,
Jon
