Getting the events of other workbooks

[xEnOnn]

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?

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