That's kind of tricky with giving examples in terms of code. Let me try
to explain, it's a general condition that I am certain is trivial to
many of you, think basic, chances are I missed some piece at the lower
level
I have some app, document based or not is not of concern, I think. In my
app I have two NSObject subclasses, myClassA, myClassB. myClassA has an
accessor, let's say for some NSString -(NSString *)myString. Now, if I
need to retrieve the value that is currently in this string, but need to
do so in myClassB, I don't know how to go about this, if instances of
myClassA and myClassB were created at the same level, so that I could
not say #import myClassA in myClassB and #import myClassB in myClassA,
which, of course, gives me a compiler error. I can either do the one or
the other, but not both. myClassA doesn't, at this stage, 'possess' an
instance of myClassB, and neither vice versa, so I have problems having
the two accessing values from each other if I do not have some central
switchboard widget that allows me to get hold of one from within the
other.
Is that clearer now?
Thank you
Alex

Umm, I have problems figuring out exactly what it is you're trying to
achieve here -- could you give an example...?
in an earlier project, managed to do so by subclassing NSApplication
You almost certainly should not be doing that...
I have done some searching but didn't come up with anything useful.
The documentation on NSApplication is nto very helpful.
.. which is probably why the documentation isn't being very "helpful".
