Hello Russell,
Eric Chatonet of So Smart Software has a fine example on how to do
this as part of his "Managing Resizing" tutorial.

In the example stack look under the "Tips and Tricks" tab and click
the "Two Fields Together" button. The script is in the divider bar.

Hi. I'm attempting to create an interface where I have two list
fields side by side. I would like the user to be able to click in
the space between the two lists and then drag left or right to and
have the lists widths to be resized.
What I've attempted to do, is to put a tall narrow rectangle in the
space between the two fields and then have it respond to the
mouseDown and dragMove messages.
They look like this:
on mouseDown
-- I set the dragdata, because the documentation led me to believe
-- it was necessary to get the rectangle to respond to dragMove
messages
set the dragdata["text"] to "text being dragged"
-- the rectangle's width is 10 and so this immediately moves the
rectangle
-- to be centered to the pointer, if the pointer escapes the
rectangle, the drag
-- operation fails
set the left of me to the mouseH - 5
end mouseDown
on dragMove
-- again, this centers the rectangle to the pointer
set the left of me to the mouseH - 5
-- this resizes the left hand field to be one pixel away from the
rectangle
set the width of field LeftSideField to the mouseH - 6
-- this gets the left hand field positioned properly again
against the left
-- edge of the window
set the left of field LeftSideField to 0
-- then, I set the width of the right hand field and fix it's
position
set the width of field RightSideField to width of this stack -
the mouseH - 6
set the left of field RightSideField to width the mouseH - 6
end dragMove
Now, this mostly works, but not as well as I'd like. If you move
the pointer too quickly (which is not hard to do), it will escape
from the rectangle and your drag operation will stop and the
dragMove messages will start making their way up the message path.
Also, even if you drag slowly enough to avoid this, when the window
is resized and the fields resize based on their geometry settings,
they are no longer within one pixel of the rectangle.
I'm thinking that there has two be a better way to accomplish what
I'm trying to do in Revolution. I'm hoping that someone out there
will be able to set me straight. Thanks in advance. :-)
