<td>Event fired before view mode has been changed and before a new file has been opened using Open method.<br>
Should be used to perform some file finalization, like saving of current file position.<br>
Note:
<ul>
<li> If you don't close currently opened file on application closing, this event is not fired.
So you may need to additionally call its handler in your form's OnClose event.
</li></ul>
