Windows.Window.frame is a Views.RootFrame which is an extension of
Views.Frame. Hence you may be able to implement your own version of:

(From the Views documentation)

===================================================
PROCEDURE (f: Frame) Close
NEW, EMPTY
Perform finalization before the frame is removed.
After a call to Close, f.view and f.rider are set to NIL and
f.ConnectTo(NIL) is called.
Close is called internally.
===================================================
