How to translate captions in TActionMainMenuBar and TActionToolBar?
Usually every TActionClientItem is linked to a corresponding TAction which provides string data for its clients. TsiLang components maintain Action’s string properties such as Caption or Hint, so all visual controls linked to the Action are updated when the active language is changed. However, those TActionClientItems that are not linked with any action, for example top-level items of TActionMainMenuBar, have no published string properties and cannot be handled directly.
