[求助]列表框数据超过256行怎么获取

caoyin

在DCL对话框中，列表框超过256行，只能读取0~255行的数据，怎样读取256行及后面的数据？？

ZZXXQQ

列表框是list_box吧。当数据量超过表高时表的右侧会出现流动条，我曾经用过三千多行数据没出问题。

;;LSP

(defun c:TT (/ id i lst flag)
  (if (and (> (setq id (load_dialog "c:\\TEST.dcl")) 0)
           (new_dialog "TEST" id)
      )
    (progn
      ;;创建1000个测试数据
      (repeat (setq i 1000)
        (setq lst (cons (itoa (setq i (1- i))) lst))
      )
      ;;写入列表框
      (start_list "list")
      (mapcar 'add_list lst)
      (end_list)
      (action_tile "accept" "(done_dialog 1)")
      (action_tile "list" "(setq lin $value)")
      (setq flag (start_dialog))
      (unload_dialog id)
      (if (= flag 1)
        (mapcar '(lambda (x) (nth x LST)) (read (strcat "(" Lin ")")))
      )
    )
  )
)

//DCL

//多选列表框

TEST
  : dialog {
    : list_box {key= "list"; multiple_select=true; }
    ok_only;
  }

测试：

运行 TT 命令

将列表中数据全选，点确定，返回如下

命令: tt

字符串的限制吧?

楼上能否说详细一点，谢谢

(defun c:TT (/ id i lst lin flag)
  (if (and (> (setq id (load_dialog "c:\\TEST.dcl")) 0)
           (new_dialog "TEST" id)
      )
    (progn
      ;;创建1000个测试数据
      (repeat (setq i 1000)
        (setq lst (cons (itoa (setq i (1- i))) lst))
      )
      ;;写入列表框
      (start_list "list")
      (mapcar 'add_list lst)
      (end_list)
      (action_tile "accept" "(done_dialog 1)")
      (action_tile "list" "(setq lin $value)")
      (setq flag (start_dialog))
      (unload_dialog id)
      (if (= flag 1)
       ;;(mapcar '(lambda (x) (nth x LST)) (read (strcat "(" Lin ")")))
        lin
      )
    )
  )
)

好像跟 (read (strcat "(" Lin ")")) 没关系，好像是 $value 的值返回问题，上面的例子仍然返回

"0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

用(setq lin (get_tile \"list\"))可以超过256

不行啊，CAD 出错退出！！

1.看不懂，你都有了lst，你就知道了列表0~999的内容了。还搞最后一句，

(if (= flag 1)
       ;;(mapcar '(lambda (x) (nth x LST)) (read (strcat "(" Lin ")")))
        lin
      )
  看不懂

2.(action_tile "list" "(setq lin $value)") $value的意思是当你点到列表的时候的返回值，你没去点$value就是默认值

3. 如果想要获取列表框中，你所选的值就是(nth lin lst),这个楼主知道。

4.   ;;写入列表框
      (start_list "list")
      (mapcar 'add_list lst)
      (end_list)

     行数是没有限制的。。。刚刚测了1万行，OK
