NAME

       d_menu_proc - Dialog procedure implementing a menu bar object. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int d_menu_proc(int msg, DIALOG *d, int c);

DESCRIPTION

       This object is a menu bar which will drop down child menus when it is clicked or if an alt+key corresponding to one of the shortcuts in the
       menu is pressed. It ignores a lot of the fields in the dialog structure, in particular the color is taken from the  gui_*_color	variables,
       and  the  width	and height are calculated automatically (the w and h fields from the DIALOG are only used as a minimum size.) The dp field
       points to an array of menu structures: see do_menu() for more information. The top level menu will be displayed as a  horizontal  bar,  but
       when  child  menus drop down from it they will be in the normal vertical format used by do_menu(). When a menu item is selected, the return
       value from the menu callback function is passed back to the dialog manager, so your callbacks should return D_O_K, D_REDRAW, or D_CLOSE.
