I took a look at the Qt# system, and found that they use a similar
method.  I've implemented it for wx.NET (not committed yet.)

In Qt, an event is sent to an object whenever an object is deleted.  I
was wondering if there is the same sort of thing for wxWindows?

In the handler of this event, I'd like to remove the reference in the
objects Hashtable.  I'm not sure if EVT_CLOSE would be suitable, unless
there's some sort of guarantee that the window will not recieve any more
events.

Alternatively, perhaps there's a way to attach to the destructor for
each wxWindow, using inheritance, or other.

Any ideas?
