You might get away with something like this on Windows,
but I seriously doubt you will get away with it in UNIX.
Typically, if you want to add widgets after you have
realized the widget hierarchy, you must destroy and
recreate the hierarchy. (There are keywords and techniques
you can use to recreate it in the same location as the old
hierarchy, etc., but basically, you have to rebuild it.)

I'm only about 80% sure of this answer. Changes in the
way widget events are handled, etc., may have changed things.
Let's just say, I would be surprised if you got this to work.

Cheers,

David
