Zoom is not going into undomanger. How can undo and redo zoom functions.
If user zooms in or zoom out then undo should goback to previous scaled position.
Can you suggest how can do this.
I don’t think you want it to undo zoom. Undo / Redo tracks changes to the GoDocument. Zoom isn’t a change to the document, it’s a change to the view parameters. Just like scrolling. Try Powerpoint or Word.
