The Log reads...2005-03-07 23:02:41.102 Chromatic
Space[934] aNotification object: <NSTextField:

How do I go from this to the float value in the
NSTextField?
Well, [aNotification object] is the textfield you want, the question
is to take the string stored there. Ok, look at the NSTextField
documentation.
Hm, nothing there. Maybe it is in one of its superclasses? (hint-hint,
NSControl).
Always look in the superclass, and its superclass, and its
superclass...!! :-)
The point is, that it is a behavior you expect from all controls, to
return the value in them at the moment, so the method would be there.
