Codename One integrates localization, deep into the framework. It becomes transparent and invisible...

Last week I wrote about the effort of revitalizing the native themes in Codename One and I'm not sure if I got the point across as I would have liked it.

The solution was to use a custom title area with two toggle radio buttons representing each tab with a line below to indicate the selected button.
