How to store the item name of a listbox in a variable?

[JuniorNogueira]

I'm trying to create a .dcl with a listbox with all my blocks, how to store the ITEM NAME in a variable?

(action_tile "accept" "(setq nameitem $value)")
_$ "1"

How to get the ITEM name?
_$ "Block 01"

Use NTH with your list of blocks.

Something like this .. will work for multiple select too:

(defun _getlistboxselection (lst sel)
  (mapcar '(lambda (x) (nth x lst)) (read (strcat "(" sel ")")))
)
(_getlistboxselection '("My" "Items" "In" "A" "List") "0 2 4")

Glad to help

If you are only looking to present the user with a single List Box as an interface, below are two ready-made functions that you may wish to call from your program:

 

List Box

List Box with Filter

 

Or at least, you could look at the code to see how the selections are handled - essentially the same technique as @ronjonp

 

Hope this helps!
