Lua Code:

  3.     self.valueText:SetText(newvalue);
  4.     self:set(newvalue);
  5. end

Note: Both tIndexOf() and Wrap() are Blizzard-defined functions located in SharedXML\TableUtil.lua and SharedXML\MathUtil.lua respectively.
more simple for me:
Lua Code:
  1. function own:getnext(tbl, item)
  2.     local found
  3.     for i = 1, #tbl do
  4.         if found then return tbl[i] end
  5.         found = tbl[i] == item
  6.     end
  7. end
