Menu Command Handler Unit

By David T. Craig, Kansas City, MO

Note: Source code files accompanying article are located on MacTech CD-ROM or source code disks.

[David has been involved with the Macintosh on the software side since its introduction in 1984. Currently he works as a Macintosh programmer for a small custom application development company in Kansas City, Kansas.]

Introduction

This unit manages menu commands in a manner similar to Apple’s MacApp “command menu” mechanism. Each application menu item should contain a unique “command number”, an integer value in the range 1 to 32767. This module scans the installed menus, parses the command numbers from each menu item, and stores the item command numbers in a table. When a menu item is selected, this module should be called to return the command number of the selected item. The parsed menu command number is also removed from the menu item.

Having each menu item define its own unique command value simplifies the job of the application programmer. Instead of using the menu id and menu item values for menu handling, the programmer needs only to use the unique command numbers. Using command numbers allows the programmer to move menu items around in the resource file without having to change the application source code. Users also benefit since they too can move menu items around via ResEdit as long as they don’t alter the item’s command number.

A menu item has a command number if the menu contains the character “#” followed by the command number. An example follows for a typical file menu (format compatible with Apple’s MPW Rez tool):

#1

“New#1”,noicon,nokey,nomark, plain;
“Open...#2”,noicon,”O”,nomark,plain;
“-”,noicon,nokey,nomark,plain;
“Quit#3”, noicon,”Q”,nomark,plain;

Note that the command number must exist at the menu item’s end.

Using this Unit

This module contains several routines which completely control access to menu command numbers.

Routine MC_Build_Menu_Command_Table builds the menu command table for an application. Call this at the start of an application after the application menus have been installed. This routine takes a pointer to a list of menu handles which define all the application menus. In Pascal a simple array of MenuHandle is adequate.

Once you are completely finished with all the menus call routine MC_UnBuild_Menu_Command_Table. This should generally be called when the application quits.

Routine MC_Fetch_Menu_Command should be called when the user selects a menu item via either the ROM MenuSelect or ROM MenuKey routines. This routine returns the command number for the selected menu item.

Routine MC_Fetch_Menu_ID_and_Item returns the menu id and item numbers for a menu command number. Once this routine is used you may use the command’s id and item numbers with the many routines supported by the Apple Menu Manager.

Routine MC_Version returns the version number and compilation date and time of this module.

Applications supporting menus that change may also use this module (MicroSoft Word is an example of an application with changing menus). Whenever the menus change you must deallocate the built menu command table and rebuild the new menu command table.

WARNING: The caller of these routines must not make any assumptions about the contents of a menu command table. This data structure, which is referenced thru a handle, must be considered off limits since its internal layout may change. Use only the public routines in this module and you will have no problems.
