    • setStringTranslator

      public void setStringTranslator(ILcdStringTranslator aStringTranslator)

      Sets the ILcdStringTranslator that this action should use to translate the Strings that will be visible in the user interface.

      This method should be called before this action is used. Any Strings already created by this action will not be translated with the specified translator.

      The following list of Strings are translated by the given instance:

      • "Delete objects"
      • "Undo {0}". {0} will be replaced by the display name of the action that is to be undone. E.g. "Undo Delete objects".
      • "Redo {0}". {0} will be replaced by the display name of the action that is to be redone. E.g. "Redo Delete objects".
      The ILcdStringTranslator needs to be able to translate what is passed in {0}, but not the entire formatted String. For example, for "Undo {0}" it needs to be able to translate "Undo {0}" itself and "Delete objects", but not "Undo Delete objects".
      aStringTranslator - The ILcdStringTranslator that should be used. Must not be null.
    • getStringTranslator

      public ILcdStringTranslator getStringTranslator()

      Returns the ILcdStringTranslator set on this action.

      The translator set on this action. Never null.
