As Graham mentioned, NSWindowController does not have a -delegate
method. The compiler seems to be telling you that you didn't
implement one yourself either.
If I had to hazard a guess, I would surmise that you are getting
tripped up by the fact that NSWindow DOES respond to -delegate and, in
practice, one often sets an NSWindow's delegate to be an
NSWindowController instance.
So, you could declare a delegate property on MyDataWindowController
and handle it that way.
An alternate approach, depending on the details of your
implementation, might be to make use of some of the other parameters
in that lengthy -beginSheet... method; setting appropriate values for
didEndSelector (and, potentially, contextInfo if your design requires
it) can probably get you what you need.
