Well, this piece of code is a bit tricky.

with:
eOSState state = cOsdMenu::ProcessKey(Key);

you call the ProcessKey function of the cOsdMenu class. It will manage 
the arrows and the back key. The 'navigation' in the menu will be ready 
out of the box. Perhaps you have a problem: you don't see the 'SetTitle' 
changing the title in the menu. I don't know if this is a bug or a 
feature, but you have to call Display() after SetTitle. If you use 
SetStatus you don't need it.

The rest of the code is ok I think, however I could suggest you to 
change it a bit:


eOSState cMyMenu::ProcessKey(eKeys Key)
{
        if(Key == kOk)
        {
                cMyItem* ci = (cMyItem*)Get(Current());
                SetTitle(ci->getCode());
		Display();
		return osContinue;
        }
        return cOsdMenu::ProcessKey(Key);
}


Hopep this helps. If there is somebody else that wants to expand the 
example even further....
