the function. The menu ID or menu item ID that you pass to User Interface Library functions
is based on a depth-first traversal of all the items in the menu tree, starting at 2. For submenu
items, the submenu itself has an ID that is one greater than the item ID of submenu entry in
the parent menu.
If you save a .tui file in the User Interface Editor in LabWindows/CVI 5.0 or higher and you
have an up-to-date include (.h) file the User Interface Editor generates, you can use the panel,
control, menubar, menu, submenu, and menu item constants in the include file as parameters
to User Interface Library functions.
Warning of Change to Text Format (.tui) Files
The order in which panel and menubar sections are written has changed to allow you to use
user interface include file constants in conjunction with .tui files. In addition, the version
number has changed from 101 to 102.
If you use .tui files to find differences between versions of your .uir files and your
generated .tui files in previous version of LabWindows/CVI, use LabWindows/CVI 5.0
tocreate new baseline .tui files for all your .uir files.
