I am aiming toward a standalone that opens and closes several stacks. I
want to prompt the user to save changes in these stacks when they are
closed. I have written "on closeStackRequest" handlers that issue such
prompts. My question now is: Is there a straightforward way to avoid
bringing up this save prompt if there have been no changes made to the
stack?
The release notes for MetaCard 2.2.1 include this statement:
Numerous improvements to the standard UI have been made, including an
improve system for prompting to save your work when exiting MetaCard,
and protection against deleting a group that appears on multiple
cards.
My experience with MetaCard's own save changes prompts seems to indicate
that MetaCard has some built-in capacity to recognize if changes have been
made to a stack and not prompt for a save if none have been made. Is there
any way that one could take advantage of this capacity?
