Thanks Martin! I'd overlooked that one. Works nicely.
(I really wasn't looking forward to rewriting this app...)

Jeremy,
To disable the default close/save alert panel you will want to
override the method
- canCloseDocumentWithDelegate:shouldCloseSelector:contextInfo:
in NSDocument, and not call super's implementation. Just throw up your
own dialog and call the shouldCloseSelector depending.

This seems like it should be easy, but I can't find a solution. I have
a document-based application in which each document (representing a
project) manages its constituent source files in a manner similar to
Xcode. When the user tries to close the document window or quits, they
are (or should be) presented with a "Save All" window which lists any
unsaved files (again, similar to Xcode).
The problem is that NSDocument's default alert panel always butts in,
and I can't find a way to disable it. I've burrowed through the chain
of methods called during window closing and application termination,
but can't find any point at which I can choke this wretched little
panel. Is there a way to do this, or am I going to have to go back and
rewrite my application without the Cocoa document architecture?
