3.4.1 LispWorks as a Cocoa application

The following startup function can be used to make LispWorks run as a Cocoa application. Typically, before calling "run" you would create an application delegate with a method on applicationDidFinishLaunching: to initialize the application's windows.

(defun init-function ()

  (mp:initialize-multiprocessing

   "main thread"

   '()

   #'(lambda ()

       (objc:ensure-objc-initialized

        :modules

        '("/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation"

          "/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa"))

       (objc:with-autorelease-pool ()

         (let ((app (objc:invoke "NSApplication"

                                 "sharedApplication")))

           (objc:invoke app "run"))))))

To use this, a bundle must be created, calling init-function on startup. For example, the following build script will create lw-cocoa-app.app:

(in-package "CL-USER")

(load-all-patches)

(example-compile-file

 "configuration/macos-application-bundle.lisp" :load t)

(save-image (when (save-argument-real-p)

              (write-macos-application-bundle "lw-cocoa-app"))

            :restart-function 'init-function)

See "Saving a LispWorks image" in the LispWorks User Guide and Reference Manual for information on using a build script to create a new LispWorks image.

3.4.2 Using a nib file in a LispWorks application

For a complete example demonstrating how to build a standalone Cocoa application which uses a nib file, see these two files:

(example-edit-file "objc/area-calculator/area-calculator") (example-edit-file "objc/area-calculator/deliver")

The area calculator example connects the nib file generated by Apple's Interface Builder to a Lisp implementation of an Objective-C class which acts as the MVC controller.
