I would actually do that in the action method. For instance, let's say that
your sheet has an text field and two buttons - OK and Cancel.

In the OK action method, I'd get the input from the text field and store it
wherever it needed to go, and call endSheet_returnCode() with a return code
of 1. In the Cancel action, I'd pass a code of 0.

In the callback, I'd first do an orderOut() on the sheet, then check the
return code. If it's 1 I'd notify anything that needs to know about the new
value read from the text field. By storing the changed data immediately but
delaying the notification until the callback, any visual updates won't
happen until after the sheet is out of the way - so the user is more likely
to notice the change.
