How can I tell if the document is dirty?
In a different thread, Walter said
[quote]Define a GoDocument.Changed event handler, perhaps by overriding
GoDocument.OnChanged and calling the base method. Look for the Hint ==
GoLayer.ChangedObject and the SubHint == GoObject.ChangedBounds.[/quote]
but how can I tell if a user starts with a clean document, dirtys it by making an edit, and then undoes the edit, returning the document to it’s clean state?
