The menu library is built using the curses library, and any program using menus routines must call one of the curses initialization routines,
such as initscr. A program using these routines must be compiled with -lmenu and -lcurses on the cc command line.
The menus package gives the applications programmer a terminal-independent method of creating and customizing menus for user interaction. The menus package includes: item routines, which are used
to create and customize menu items; and menu routines, which are used to create and customize menus, assign pre- and post-processing routines, and display and interact with menus.
Current Default Values for Item Attributes
| |
The menus package establishes initial current default values for item attributes. During item initialization, each item attribute is assigned the current default value for that attribute. An application
can change or retrieve a current default attribute value by calling the appropriate set or retrieve routine with a NULL item pointer. If an application changes a current default
item attribute value, subsequent items created using new_item() will have the new default attribute value. The attributes of previously created items are not changed if a current default
attribute value is changed.
