Tree Widget: hilitedValue?

[Brian Milby]

I don't think there is an existing one liner, but it can be done a couple
ways.

Here is a recursive function defined in the PI code for Custom Props:

on fetchArrayDataOnPath pPath, pArray, @rData
   local tKey
   put item 1 of pPath into tKey
   if the number of items in pPath is 1 then
      if tKey is not among the keys of pArray then
         return "no such key"
      else
         put pArray[tKey] into rData
         return empty
      end if
   else
      delete item 1 of pPath
      fetchArrayDataOnPath pPath, pArray[tKey], rData
   end if
end fetchArrayDataOnPath

There are other handlers in that script that could be useful as well
(add/set/delete).

You could also turn the path into an array (but lose the error checking
above):

function getValue pArray, pPath
   split pPath by comma
   return pArray[pPath]
end getValue

Thanks,
Brian
