Stack Height/Menubar

[J. Landman Gay]

I haven't needed to create menubars for some time, but this is how it has 
always worked in the past:

LiveCode menus are objects that take up room at the top of a card. On 
Windows, this is standard; menus appear at the top of each window. When the 
same stack is run on a Mac, LiveCode pushes the top portion of the card 
above the top border of the window, out of view. The body of the window 
shortens to accomodate only that portion of the card that contains the 
actual stack content. The card is still technically the same height, but 
the part of the height that contains the menu group is hidden from view. 
LiveCode handles this window resizing transparently between platforms.

When the menu scrolls out of view, the actual content area will be, in this 
case, 800 pixels high. The other 22 pixels are above the top of the 
viewable area. You do not need to set the menu group invisible because it 
won't be in view. While you are working it's convenient to not set the 
group as the system menu. That way you can see where placement of the 
controls should go relative to the area that will disappear later. When 
layout is done, set it back to be used as the stack menubar so it will 
behave as you want.

If the menu group is not placed on every card, those cards will not scroll 
and the full height of the card is displayed. If you place the menu group 
on every card so the size remains consistent everywhere, the redraw problem 
at the bottom of the card shouldn't happen.

If you have already placed controls under the menubar area, you'll need to 
move them down.

Menubar behavior on Mac is a little quirky but it does allow you to write 
once and run on any OS, which is what LC is all about. As long as you don't 
make the menu group invisible, the stack will look as expected everywhere.
