Every Mac OS X program has a main menu bar—that familiar sight at the top of your computer's screen. Although every application adds its own menus and menu items, there is a fair amount of similarity between each program. Most programs have File, Edit, Window, and Help menus, for example. The guidelines for how menus should look and behave can be found in the Apple Human Interface Guidelines, which you learned about in Chapter 2.
In this Try It Out example, you create a menu bar for a Carbon application. Interface Builder provides some nice graphical tools for building menus, and it also sets up many of the common menus for you.

Click once on the File menu in your menu bar window. The File menu drops down, as shown in Figure 4-5. Notice that a bunch of items have already been filled in for you.
