Hi
I have a custom NSView subclass that contains, among other things, an
NSTableView and need to know when focus changes happen so I can
highlight the the view correctly. I tried setting up a KVO observer on
NSWindw's "firstResponder", but it appears that windows don't report
this change.
I'd like to do this without resorting to subclassing dozens of class
to broadcast when they receive a "becomeFirstResponder" or
"resignFirstResponder" message. What is the best way to go about
detecting responder changes in subviews of a custom view?
Thanks for any help
