Re: programmatic layout of controls

[Tom Sheffler]

Thanks Fred.

Indeed, that was a missing line!  

Compiles now.  Do not see any views.

Updated screenshot and description in repo.  Still not sure how to use this correctly for layout.

Thanks,

Tom

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
