How to insert CFString into LPopUpButton

Hi there,

I am localizing my application, and searching how to put/insert
CFString in PopUpButton.
Here is the snippet of the code.

else if ( (l_popUpList = dynamic_cast<LPopupButton *>(pane) ) != NULL)
{
	Str255 l_pData;
	l_popUpList->GetMenuItemText(l_popUpList->GetValue(), l_pData);
	MapIDToUnicode(&l_pData, &dst);
        if( NULL != (cfS =
CFStringCreateWithPascalString(kCFAllocatorDefault, dst,
kCFStringEncodingUTF8)))
		{
		   // This method does change but not each and every items inside the
popup
                     l_popUpList->SetCFDescriptor( cfS );
                   // ?????? Here want to use something like
InsertMenuItem(...)
		     CFRelease(cfS);
		     l_popUpList->Refresh();
		}
}

Appreciate with your advice!

Thanks!
