Hi all,
I've a window with a fairly complex layout - one NSTextView and several
tables, all displaying different types of data. To keep things in order,
I've created a model object that holds the data for all these interface
elements. The window may also hold several instances of the model object and
I list them in a table.
My problem is how to keep the undo manager for the text view synchronised
with a particular instance of a model object. As the user switches between
model objects, I want him to be able to do cmd + z transparently with the
window knowing what changed in that particular instance.
Some research seems to indicate that using core data would give me this for
free - make my model objects extend NSManagedObject and I would have undo
for free. Is this correct?
