Well, ALIGN_RIGHT has the right name to give you hope,
but none of the functionality, unfortunately. That is to
say, it doesn't do what you think it does. :-)

If you want to position a top-level base next to
another top-level base, that is easily done. Find
the position and size of the first TLB:

Widget_Control, TLB_1, TLB_GET_OFFSET=offsets, $
TLB_GET_SIZE=sizes

Then, position the second TLB next to the first:

Widget_Cotnrol, TLB_2, XOFFSET=offsets[0] + sizes[0] + 10, $
YOFFSET = offsets[1]

The window is not "glued" to anything, and if either window
is moved, you won't know about it unless you have TLB_MOVE_EVENTS
set for the TLBs. If you do, you can figure out where the
window moved to and reposition things.

Cheers,

David
