In my app, I have implemented an NSUndoManager and everything is working
beautifully. I also have a preference pane version of the app which is
working except for undo. I create a undo manager in my subclass of
NSPreferencePane and when I add an operation to the undo stack, the undo
manager does exist. However, I can't undo the operation. I've even
implemented - (NSUndoManager *)undoManager in this object. I believe
that the problem is that something is supposed to get put in the
responder chain but I don't know what goes in the chain, which chain, or
how to add it to the chain. (Do I add my subclass of NSPreferencePane
to System Preferences window (or my interface window?) using a method
that I'm not finding?) Is there an undo manager in the System
Preferences app that I can get ahold of?
This is all done for me when creating a normal app, but I'm lost now
since I haven't really done much with the responder and is a little
foreign to me. If someone could help me out, that'd be swell.
