Linking the "document edited" flag to the Undo menu item state

Subject: Linking the "document edited" flag to the Undo menu item state

Hi everyone,

I am writing an application that offers support for Undo/Redo. Everything works fine, except for a small detail that bothers me.

Since I set the document edited flag manually, using the [theWindow setDocumentEdited:YES] instruction each time the document is modified, I have no way to remove the flag when a user undoes all the changes.

The solution would be to set the document edited flag based on the status of the Undo menu item state. Is there a simple way to do this?

Thanks in advance,

Huibert
