Hi guys,
Sorry about the last email I sent to the list (I went to close the
window and by accident hit send!) anyway, my problem is this:
I have a NSDocument based application, and its based on editing text
documents (in a subclassed NSTextView). Now, I can't remember when this
problem started, but it turns out that, if a user creates a new file
and starts typing, undo seems to work fine. If they then save their
work, and begin typing again, undo doesn't seem to work as expected. By
unexpected, I mean the dot doesn't show in the title bar close button.
If I go to edit (menu bar) and try undoing (it seems to record undo-ing
fine) it works fine. A person I know told me I should use
setDocumentEdited: on things like saveDocument, and textDidChange etc.
So I did this, and this (in a very hackish sort of way) works. But it
won't always, undo just gives up sometimes :-).
I was wondering if anyone else had, had this problem before and if
there was a workaround (apart from the setDocumentEdited:)?
Thanks for any help,
Oliver
