Hi,

I use LispWorks HobbyistDV on Windows 10, and I'm trying to build a simple GUI app.


The code is as follows:

***************************************************************
(defpackage "MY-PACKAGE"

　(:add-use-defaults t)　(:use "CAPI"))

(in-package :my-package)

(setq interface

      (make-instance 'interface

                     :visible-min-width 200

                     :title "My Interface"))

(setq button

      (make-instance 'push-button

                     :data "Hello" 

                     :callback

                     #'(lambda (&rest args) 

                         (display-message 

                          "Hello World"))))

(contain button)
***************************************************************

And I face with the error as bellow:


***************************************************************
Quitting because of error:

   Trying to use CAPI without Multiprocessing
***************************************************************

Could you tell me how to fix this issue?

I'd appreciate your help.

I should have read the tutorial of application builder before I posted the question.
I read the tutorial and, I write down the example script.

************************************************************************

(capi:define-interface demo ()

  ()

  (:panes

      (page-up capi:push-button

               :text "Page Up"

               :selection-callback 'scroll-up)

      (page-down capi:push-button

                 :text "Page Down"

                 :selection-callback 'scroll-down)

      (open-file capi:push-button

                 :text "Open File"

                 :selection-callback 'file-choice)

      (viewer capi:editor-pane

              :title "File:"

              :text "No file selected."

              :visible-min-height '(:character 8)

              :reader viewer-pane))

   (:layouts

     (main-layout capi:column-layout 

                  '(row-of-buttons row-with-editor-pane))

     (row-of-buttons capi:row-layout

                     '(page-up page-down open-file))

     (row-with-editor-pane capi:row-layout

                           '(viewer)))

   (:menus 

     (file-menu "File"

                (("Open"))

                :selection-callback 'file-choice)

     (page-menu "Page"

                (("Page Up" 

                  :selection-callback 'scroll-up)

                 ("Page Down"

                  :selection-callback 'scroll-down))))

   (:menu-bar file-menu page-menu)

   (:default-initargs :title "Demo"))

(capi:display (make-instance 'demo))

***************************************************************************

I loaded the script on Application builder and set demo as the starting function,
then the building script was made.

*****************************************************************************

;;; Automatically generated delivery script

(in-package "CL-USER")

(load-all-patches)

;;; Load the application:

(load "//Mac/Home/Documents/test3.lisp")

(compile-system 'capi :load t)

(deliver 'demo "//Mac/Home/Desktop/test" 0

         :interface :capi)

*****************************************************************************

I loaded the building script and I tried to build.
But I faced the same error again.

I cannot find the good tutorial of the application builder.
Does anyone know the good tutorial?

I'd appreciate your help.
