I want to run a script when a particular popup dialog is closed, but I’m not sure how to approach it. I haven’t found anything in DialogMonitorOps or UIAccessor which can handle that (no pun intended). I can TELL Max to close a dialog, i.e. UIAccessor.CloseDialog hwnd, but can’t figure out how to watch for it happening.
Ideally, I’d like something which would trigger both on clicking the dialog’s “X” button OR when the close dialog method mentioned above is used.
Can anyone help me out on this?
What do you know about the NativeWindow?
As of now, nothing. But since you’ve given me a starting place, I will soon know whatever the help files have to say about it.

you can use DialogMonitorOps to hook a specified opened dialog
read a documentation about how to destroy a nativewindow …
I think I’m in a bit deeper water than where I can swim right now.
EDIT:
I just want to clarify that I just meant that I don’t really know what I’m doing. The code you sent me works perfectly, even if I don’t understand it just now.
the native window allows to hook messages of a assign window…
i’ve overwrote WindProc and added new event handler to a native window object.
now when an assigned window receives any message i see it with the native window, and fire event in case of Window Destroy message
