Programmatically Show Versions Popup Menu for Document-Based App

Question

We have a custom window and titlebar for a document-based app, and we would like to support versioning with the standard disclosure button that appears beside the document title. Here is an image of the disclosure button and the popup menu when it is clicked (from TextEdit):

Is there a way to programmatically show this versions popup menu for a custom disclosure button?

Answer 1

I think you can't show programmatically the system version menu, but you can create your own and call the NSDocument methods

- (void)lockDocument:(id)sender
- (void)duplicateDocument:(id)sender
- revertToContentsOfURL:ofType:error:
- (void)browseDocumentVersions:(id)sender

lockDocument and browseDocumentVersions require 10.8
