Changing the width of a stack

[Peter Haworth]

Thanks to all for the suggestions, particularly Richmond and Mike whose
solutions both involve moving the centered control to the left edge of the
stack instead of trying to move the left edge of the stack to the centered
control. The problem with globalloc and width and other stack related
properties is they don't change the position of the left edge of the stack
relative to the left edge of the centered control

I suspected moving the centered control to the left edge of the stack would
be reuired, just seems like there should be a more elegant way to do this,
perhaps something like "position the left of stack xyz to the left of
control abc".
