Re: programmatic layout of controls

[Fred Kiefer]

Hi Tom,

I had a very short look at your stack view test code and could not see where 
you create the object `hbox`. This might be completely unrelated to the issue 
you are having with that code but maybe it points you in the right direction.

Cheers,
Fred
