Re: Detecting A Changed Cell When Editing Ends

You always get the DidEndEditing whether any changes happened or not. 
You can either compare the value at that time with the original value
to see if it changed, or you can also catch DidChange and make a note
of it.

The first requires you know what the original value is, but usually the
text field is reflecting a model value somewhere so often this is easy
enough.  The second requires a little book-keeping, and it also will
have false positives if I edit the field but wind up editing it back to
the same value it had originally.
