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.
