const Document & | document () const |
Return a const copy of the Document for non redo/undo interaction. | |
MainWindow & | mainWindow () |
Return the MainWindow so it can be updated by this command as a last step. | |

Save, when called the first time, a hash value representing the state of the Document.
Then on succeeding calls the hash is recomputed and compared to the original value to check for consistency. This "post" method is called immediately after the redo method of the subclass has done its processing. See also saveOrCheckPreCommandDocumentState
