Recommended Posts

Hello all
Hello to @Lee Mac
Is it possible to modify the code  List Box Synchronisation   to run without a  DCL File   
Please help from you

http://www.lee-mac.com/listboxsync.html

 

(defun c:listboxexample ( / *error* UpdateList data dclfile dclhandle )

  ;; This program demonstrates how to update a secondary list_box based
  ;; on user selection from a primary list_box.

  ;; Example courtesy of Lee Mac © 2010 (www.lee-mac.com)

  ;; Accompanying DCL File:

  (setq dclFile "listboxexample.dcl")
  
  ;; Ensure this file resides in an AutoCAD Support Path

  (defun *error* ( msg )

    ;; Error Handler - will unload the dialog
    ;; from memory should the user decide to hit Esc

    (if dclHandle (unload_dialog dclHandle))
    (or (wcmatch (strcase msg) "*BREAK,*CANCEL*,*EXIT*")
        (princ (strcat "\n** Error: " msg " **")))
    (princ)
  )

  (defun UpdateList ( key lst )

    ;; This function updates the list_box associated with the specified key
    ;; using the contents of the supplied lst

    (start_list key)
    (mapcar 'add_list lst)
    (end_list)
  )

  ;; Data used to Populate List_Boxes:
  ;; I've chosen to use this list structure because it suits the data,
  ;; but there are many other possibilities.

  (setq Data
   '(
     ("Audi"    ("TTS Quattro" "TT RS" "S3 Quattro" "S4 Quattro" "S5 Quattro" "RS5 Quattro" "RS6 Quattro"))
     ("BMW"     ("M3" "M5" "M6" "X5" "Z3" "Z4"))
     ("Porsche" ("911" "924" "928" "930" "944" "Boxster" "Cayenne" "Cayman"))
     ("Jaguar"  ("XF" "XJ6" "XJR" "XKR" "X-Type" "S-Type"))      
    )
  )

  ;; Start of Main Routine
  ;; Lots of Error Trapping to make sure the Dialog Loads:

  (cond
    ( (<= (setq dclHandle (load_dialog dclFile)) 0)

      (princ "\n--> DCL File not Found.")
    )
    ( (not (new_dialog "listboxexample" dclHandle))

      (setq dclHandle (unload_dialog dclHandle))

    )
    ( t

      (or *Make*  (setq *Make*  "0"))
      (or *Model* (setq *Model* "0"))

      ;; Set up some default selections, for the first-time running of the program.
      ;; The variables *Make* & *Model* are intended to be global and hence will
      ;; remember the user's last selections.

      ;; Populate the List_Boxes:

      ;; List_Box 'lst1'
     
      (UpdateList "lst1" (mapcar 'car Data))
      (set_tile "lst1" *Make*)

      ;; List_Box 'lst2'

      (UpdateList "lst2" (cadr (nth (atoi *Make*) Data)))
      (set_tile "lst2" *Model*)

      ;; Action_tile Statements:
      ;; These control what happens when the user interacts with a tile in the dialog.

      (action_tile "lst1"
        (strcat
          "(UpdateList \"lst2\" (setq lst2 (cadr (nth (atoi (setq *Make* $value)) Data))))"
          "(setq *Model*"
          "  (set_tile \"lst2\""
          "    (if (< (atoi *Model*) (length lst2)) *Model* \"0\")"
          "  )"
          ")"
        )
      )

      ;; Here, when the user selects an item from 'lst1', the UpdateList subfunction
      ;; is fired to update the items in list_box 'lst2'.

      ;; list_box 'lst2' is also set to the value of *Model* if the index is
      ;; available for the selected item, else the first item is selected.

      ;; Note that $value is a string containg the index of the item
      ;; that the user has selected.

      (action_tile "lst2" "(setq *Model* $value)")

      ;; Dialog setup, lets start it:

      (start_dialog)
      (setq dclHandle (unload_dialog dclHandle))
    )
  )
  (princ)
)

 

DCL File

// DCL File to be saved as listboxexample.dcl

Thank you

Are you saying you want the dcl to be created as required from your code, it does not exist, simple just add the write dcl to file to your code. 

 

(setq fo (open (setq fname (vl-filename-mktemp "" "" ".dcl")) "w"))

 

Just look at Multi radio buttons.lsp in "Downloads". This method is used by lots of us plenty of examples.

Since writing that particular tutorial, I have developed my DCL List Tile Dependency function, which extrapolates & generalises the concept to extend to and accommodate any number of dependent/synchronised DCL list tiles (whether they be list boxes or popup lists), nested to any number of levels deep.

 

Furthermore, the ListTileDependencyDemo.lsp demo program available to download from that page incorporates the DCL definition as part of the AutoLISP program, writing & loading the supporting DCL file during the evaluation of the AutoLISP function.

Thank you 

Yes, this is what I want
Thank you for the support and what you do for us and others
