I can't seem to find "windowDidMakeFirstResponder:" in any API or
reference I have handy. By any chance is it private? There may be a
reason it is private, namely that at the time it is called, the
responder chain may not be not complete.
This ain't Windows. The unpublished APIs aren't hidden gold.

I'm expecting the DelegatingView class to handle an action I wrote
called "noteFirstResponder:" which I send to the first responder when
it changes. I send it from the window controller's
windowDidMakeFirstResponder: method like so:
[NSApp sendAction:@selector(noteFirstResponder:) to:nil from:nil]
...
In my tests, the first responder is a checkbox within a
DelegatingView. I make the checkbox the first responder by tabbing to
it. The checkbox gets a focus ring, and windowDidMakeFirstResponder:
is called, so the checkbox should be the first responder and should
get the "noteFirstResponder:" action.
However, I can't trace execution past the sendAction:to:from: call. I
put breakpoints on the DelegatingView's tryToPerform:with: and
doCommandBySelector: methods, but they never get hit. This would seem
to mean that the DelegatingView is not actually part of the responder
chain, or else noteFirstResponder: does not get passed along the
responder chain, both of which seem very unlikely.
