Hi Peer, sorry no there isn't any mechanism currently set up for a script to be run at shutdown time.

One way to avoid PromptSaveChanges from being shown is to all moi.exit( true /* NoQuerySaveChanges */ );

or also another way is if you clear the current content using moi.geometryDatabase.fileNew( true /* NoQuerySaveChanges */ );

Otherwise the way that PromptSaveChanges will be shown is when the last saved revision number is smaller than the current geometry database revision number.

Hi Michael,

Thanks for the tips about NoQuerySaveChanges and for the specifics on when PromptSaveChanges is shown.

That's a shame about not being able to run a script at shutdown since it seems like the X on the window for closing the window and also "Quit Moi" (on macOS) are outside of the html environment and so it's not like I can hook up script to them like html buttons.

I guess I'll have to add a Quit button somewhere and be careful to not use those other buttons that I'd normally go for and also be careful to not do cmd-Q. Unless you have any other ideas about how I can ensure that quitting always goes through a script.

Hi Peer,

re:

Sorry no there isn't any way that I'm aware of that would enable a script to take control of program shutdown.

In addition to window close button or Cmd+Q it can also be triggered by user logout or OS shutdown.

Hi Michael,

Thanks for explaining what causes PromptSaveChanges to get shown. I was able to get the behavior I want by doing this:

// force PromptSaveChanges to be shown when MoI exits
moi.geometryDatabase.incrementRevision();
moi.geometryDatabase.setUserText('dummy', 'dummy');
