Abstract
A computer system runs an operating system and an application program, where the application program outputs a menu item as part of a menu on an output device. A function is provided in the operating system for specifying a checked bitmap or other image representation for the menu item and an unchecked bitmap or image representation for the menu item. The checked bitmap includes a check mark beside the text of the menu item and the unchecked bitmap lacks such a check mark. This function is called to specify at least one of these bitmaps. The application program uses the bitmaps when outputting the menu. This approach facilitates readily changing bitmaps for a menu item in a checked or unchecked state to accommodate changes in menu scaling and other changes in appearance of menu items.
