# d\_menu\_proc(3alleg)

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

## 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.
