Method XbpMLE():undo() Foundation

Undo changes in the edit buffer.

:undo() --> lSuccess

This method returns the value .T. (true) if the changes made to the edit buffer could be undone, otherwise .F. (false) is returned.


The method :undo() resets the text in the edit buffer to what it was before editing began. For this method to be successful, the instance variable :undo must contain the value .T. (true) (this is the default setting). Changes can be undone until the method :getData()is executed.
