      public void actionPerformedImpl(ActionEvent e, RTextArea textArea)
      Description copied from class: RecordableTextAction
      The actual meat of the action. If you wish to subclass this action and modify its behavior, this is the method to override.
      Specified by:
      actionPerformedImpl in class RecordableTextAction
      Parameters:
      e - The action being performed.
      textArea - The text area "receiving" the action.

    • getMacroID

      public final String getMacroID()
      Description copied from class: RecordableTextAction
      Returns the identifier for this macro. This method makes it so that you can create an instance of the RTextAreaEditorKit.CutAction action, for example, rename it to "Remove", and it will still be recorded as a "cut" action. Subclasses should return a unique string from this method; preferably the name of the action.

      If you subclass a RecordableTextAction, you should NOT override this method; if you do, the action may not be properly recorded in a macro.

      Specified by:
      getMacroID in class RecordableTextAction
      Returns:
      The internally-used macro ID.
