I have a custom NSView subclass that contains, among other things,
an NSTableView and need to know when focus changes happen so I can

on NSWindw's "firstResponder", but it appears that windows don't
report this change.
I think NSWindow sends an NSNotification in that case. At the least,
it would send a method to its delegate.
I don't believe this is the case, except maybe for the field editor
notification, but that wouldn't fire in all cases. windowDidUpdate:
may be sent, but probably really often so the method needs to be
pretty efficient.
Another option--just theorizing, as I have never done it--may be to
subclass NSWindow and overrride -selectNextKeyView:, –
selectPreviousKeyView:, and/or -makeFirstResponder:.
