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.
