    • discardAllUndoableEdits

      public void discardAllUndoableEdits()
      Get rid of any accumulated undoable edits. It is useful to call this method after opening a file into the text area. The act of setting its text content upon reading the file will generate an undoable edit. Normally you don't want a freshly-opened file to appear with its Undo action enabled. But it will unless you call this after setting the text.
