List Box, How Do You Highlight The Value?

[The Buzzard]

Hello to all,

 

I decided to switch from popup_lists to list_boxes in one of my dcl's. I have the default values set and they work fine. The problem I am having here is the values do not highlight when the dcl first appears. I tried using value = 0;, But this did nothing so I removed it.

 

Is something missing? I would appreciate any help on this.

Thanks

 

             : column {
              : boxed_column {
                label = "Class";
                : list_box {
                  key = "CLASS";
                  height = 8.0;
                  width = 9.0;
                  fixed_height = true;
                  fixed_width = true;
                  alignment = centered;
                }
              }
            }
            : column {
              : boxed_column {
                label = "Size";
                : list_box {
                  key = "PSIZ";
                  height = 8.0;
                  width = 9.0;
                  fixed_height = true;
                  fixed_width = true;
                  alignment = centered;
                }
              }
            }

i think (mode_tile key mode) does this

[The Buzzard]

Thanks John,

 

But mode_tile will focus attention to the tile, It will not highlight it.

[JohnM]

you want to highlite a particular item correct?

i think you use set_tile then mode tile to mode 3

[The Buzzard]

you want to highlite a particular item correct?

i think you use set_tile then mode tile to mode 3

That would work for edit box contents, Not list box.

[JohnM]

Here ya go, save the dcl and lisp file then in AutoCAD map a path to the folder load the files in the vlide editor and run the lisp file and you will see the items in the list boxes highlighted. In the lisp file you will see set_tile set to the item in the list and mode tile set to highlight them . You can create variables for these to be remembered .

(set_tile <key> "1")

[The Buzzard]

(set_tile <key> "1")

Thanks Lee,

 

But it does not do a thing. I am using radio buttons to set the values of the Class list and the Class list in turn sets the value for Size list. The initial problem is when the dialog firsts starts there is no highlighting of the first value in each list as per the default setting.

 

Once selected the values are highlighted and remembers their last selection when the dialog reappears.

 

I do not use list boxes too often, But in this case it seemed like a nice change. Boy was I wrong.

[Lee Mac]

Buzzard, its not too difficult, list boxes work in the same way as popup_lists (oh, and it should've been "0")

 

An Example:

 

(defun c:test ( / dc f lst item )
 (cond
   (
     (or
       (<= (setq dc (load_dialog "ListBox.dcl")) 0)
       (not (new_dialog "test" dc))
     )
   )
   (t
     (start_list "lst")
     (mapcar (function add_list) (setq lst '("Item1" "Item2" "Item3")))
     (end_list)

     (setq item (set_tile "lst" "0"))

     (action_tile "lst" "(setq item $value)")

     (setq f (start_dialog) dc (unload_dialog dc))

     (if (= f 1)
       (alert
         (strcat "You Selected: "
           (nth (atoi item) lst)
         )
       )
     )
   )
 )
 (princ)
)

test : dialog { label = "List_Box Example";
 spacer;
 : list_box { label = "Select Item"; key = "lst"; }
 spacer;
 ok_cancel;
}
            

Save the DCL as ListBox.dcl

[The Buzzard]

Here is the incomplete code with dcl. It will run, But is not set to do anything as of yet. But you will see what I am describing.

I tried it with 0 and have the same issue.

[Lee Mac]

Check my example.

[The Buzzard]

Check my example.

 

 

I just tried this:

 

           (setq AF:CLASS# (set_tile "CLASS"  "0"))
          (setq AF:PSIZ#  (set_tile "PSIZ"   "0")) 

 

Size highlights now, But not Class.

[Lee Mac]

I only set the variables so that the variables have the tile_value if no item is selected before the user hits OK.

 

The set_tile statements are the functions that highlight the list_box items - there isn't too much that can go wrong.

Ok, I moved the function calls for the List Extraction above the set_tile calls and it works now.

 

 

Thanks a lot, Thats the ticket.

 

        (t (start_list "CLASS" 3)(mapcar 'add_list CLASS_LST)(end_list)
          (start_list "PSIZ"  3)(mapcar 'add_list PSIZ_LST) (end_list)
          (AF_MT)
          (AF_CLU)
          (AF_SLU)
          (set_tile AF:FTYP$ "1")
          (set_tile AF:VIEW$ "1")
          (set_tile AF:FACE$ "1")
          (set_tile AF:DUNT$ "1")
          (set_tile "DF" AF:DF$)
          (setq AF:CLASS# (set_tile "CLASS" "0"))
          (setq AF:PSIZ#  (set_tile "PSIZ"  "0")) 

[The Buzzard]

Lee,

 

I am still seeing some quirky things happening with this arrangement. I am sure you gave a correct procedure to use. I will look over the sample code more completely and experiment a bit.

 

I will let you know what I find.

[Lee Mac]

Good luck.

[The Buzzard]

Lee,

 

After careful review of looking over your code and seeing how I could apply it to mine, I found that these are just two different situations. The code you are showing has one list with nothing controlling its contents such as a radio button or another list. My situation has radio buttons controlling the contents of the first list and the first list contolling the contents of the second list. Each time something is done to any of these controllers the highlighting disappears. There must be another way to do this, But nothing comes to mind. I have been changing this code around for days just to get past these obstacles. I guess i will let this one rest a while till I can find something similar to this situation.

 

Thanks for your help anyway,

The Buzzard

[Lee Mac]

Hi Buzzard, I posted my example to be the simplest possible - I shall try to post an example that would apply to your situation.

[Lee Mac]

Buzzard,

 

Have fun playing around with this one
