The critical piece that isn't always clear is that the menu bar doesn't
count as part of your display area; think of it in the same way as the
window title bar. It does exist in the stack and takes up space there,
but all content should be considered separately from that (it has to be,
otherwise on Windows any objects above that will intersect with the
menus.) To add a menu bar after the stack is already laid out, increase
the height of the stack by the height of the menu group, move all your
current content down that much, and put the menu bar group in the
now-empty space at the top. The actual content area is still 16:9, and
is the area below the menu group.
The menu builder tool will do the moving for you if you select the "set
as stack menu bar" checkbox on a stack that doesn't have a menu
assigned. Alternately you can use my "pushdown" handler to do it. First
increase the height of the stack by the height of your menubar group.
Then run this:
on pushDown tH,tY
if tH = "" and tY = "" then
ask "Enter horizontal and vertical offsets:" with "0,38"
if it = "" then exit pushDown
put item 1 of it into tH
put item 2 of it into tY
end if
if tH = "" then put 0 into tH
if tY = "" then put 0 into tY
set cursor to watch
repeat with x = 1 to the number of bgs
set the left of bg x to the left of bg x + value(tH)
set the top of bg x to the top of bg x + value(tY)
end repeat
repeat with x = 1 to the number of cds
go cd x
repeat with n = 1 to the number of cd controls
set the left of cd control n to the left of cd control n + value(tH)
set the top of cd control n to the top of cd control n + value(tY)
end repeat
end repeat
end pushDown
Call it from the message box this way:
pushdown 0,27
If the menu is already in place, the handler will move it down with
everything else so you'll have to drag it back up to the top. When
that's done, you'll see that the actual display area is still the same
proportions as before. On a Windows machine the menu will be in the
stack window as required, and the ratio of the actual content area below
it will be 16:9. On a Mac, the menu will scroll up out of view but the
visible area will still be 16:9.
