Accessing undo stack?

  • Subject: Accessing undo stack?

Hi folks.

I have an NSTextView that i am using as a text-editor. When the contents are changed, i set a flag to say that Edited=True, and use [NSWindow setDocumentEdited:hasChanged] to notify the window that an edit has happened (sets the little dot in the red top-left button).

Now if I do apple+z to undo, then my text-editor is now not edited - however I am not sure how to check this - I am thinking it may be possible to look at the Undo-stack, and if nothing is on it then I can assume that an edit has not happened? Is this a good approach to take? Can anyone offer any advice?

Cheers.
