Subclass NSTextView and override -changeFont: -changeAttributes:

disableUndoRegistration, call super, then turn it back on again.
I have to apologize for not stating my problem more clearly. Let's
try again:
I do want to see "Undo Set Font" or "Redo Paste Font" etc. in my Edit
menu. So disabling the undo manager is probably not the right thing.
Currently NSDocument does, whenever the undo stack changes:
document is dirty if and only if size of undo stack > 0
What I want it to do is:
document is dirty if and only if number of "real" operations in undo
stack > 0.

I have a document based Cocoa editor, which handles simple text
files (setRichText: NO).
It handles undo and font changes.
But the files are just plain text files; no font information gets
stored.
So I would like that the document does NOT get dirty
(isDocumentEdited) if only the font has been changed.
This would imply that we have two kinds of changes: "real" changes
(like typing, cut and paste of text, etc.) and "ephemeral" changes
(e.g. change of font).
Both are recorded by the NSUndoManager, but only "real" changes
make the document dirty.
How could this be done in 10.4.11 ?
Kind regards,
Gerriet.
