How do I add an event listener for when pages are deleted?

[MarkP]

I’m trying to add a method that gets called when pages are deleted through the UI.

I’ve tried calling instance.Core.documentViewer.addEventListener() with “removePages”, “removePage” and “delete” but none of them worked. I can’t find anything else in the documentation that suggests how to do this.

Hello Mark,

The events for page alterations (adding, deleting, and moving pages) is all wrapped into 1 event: layoutChanged
Here is the API reference for layoutChanged

The event will return details on which operation was performed and on which pages.

Please let me know if there are any issues.
