Script with Event Listeners

[erieru103]

Hi

I want to create a tool that it will give a warning when the cross-reference marker is deleted while editing documents.

Is it possible to do it using Event Listeners?

If it is possable, I am considering the following properties,

which of the following properties should I use?

Event.AFTER_CONTEXT_CHANGED

Event.AFTER_DELETE

Event.AFTER_PLACE

Event.AFTER_SELECTION_CHANGED

If it is not possible, is this possible only with a plugin?

Can anyone give me some advice?

Regards.

Does using the options in the preflight panel provide a solution?
