Moving controls smoothly around the screen

[Peter Haworth]

Hi Craig,
You pretty much have it.  I've seen it referred to as "an accordion"
elsewhere.

Perhaps to clarify further, the initial display would be:

Button1
Button2
Button3
Button4

WHen Button 2 is clicked, the display would be:

Button1
Button2
  Group2
Button3
Button4

If Button 1 was then clicked:

Button1
  Group1
Button2
  Group2
Button3
Button4

If Button1 was then clicked again:

Button1
Button2
  Group2
Button3
Button4

In answer to your question, yes I could temporarily group the objects to be
moved and move them all as one entity.  But I'm missing how that helps with
the need for smooth movement.  The show command doesn't help since all the
objects to be moved are already visible and, so far, I haven't found a way
to make the move command do anything but snap the moved objects from their
original location to the new one.
