Livecode 如何复制选定行的内容

如何将选定内容复制到一行中。在下面代码的帮助下，我得到了行的行号。但我不知道如何复制特定行的内容

on mouseUp
   put the dgHilitedLines of group "data" into theLine
   answer theLine
end mouseUp

---

设置全局clipboarddata属性以设置剪贴板：

on mouseUp
   put the dgHilitedLines of group "data" into myLine
   set the clipboarddata["text"] to line myLine of the dgText \
     of grp "data"
end mouseUp
