I think there is a misunderstanding.
I am using the LocalisedStrings ability to set a customized tooltip (and not only) for each separate UI compoment, where the typical line ("hello" = "bonjour") in the LocalisedStrings-file has the following form :
"UI name" = "tooltiptext"
So, with this trick, I can define tooltips in multiple languages, according to the region of the user.
However, at initialization phase, when I am trying to find out the name of each child UI element contained in the setContentOwned-maincomponent, I receive some "internal" elements as I explained in my first message.
So, is there any characteristic in order to reject these elements?
Edit : Ok! I can handle the case in which the string (the UI element name) not found in the file.
The translate() function "If the string isn't found in the list, the resultIfNotFound string will be returned".
