Getting the events of other workbooks

How do I refer to an event and create a function for the event of another workbook?

I have a AddInWorkbook.xla that works as a add in and it needs to refer to whatever new workbook that the user opens. I need the new workbook to tell the AddInWorkbook.xla when the new workbook's closing event is dispatched.

So it is possible to do something like this in VBA Excel?

Or otherwise like adding a event listener to it? Possible?

PHP Code:

---

//inside AddInWorkbook.xla
ActiveWorkbook.addEventListener("Workbook_Close", closeHandler)
function closeHandler(Event e) {
   if e.filename == ActiveWorkbook.filename {
      //then from here I can carry on...
   }
}

But how do I declare the events and set the class to the application? Are there any examples? Sorry as this is the first time I am doing this.
