Re: Tk::Hlist questions

It makes sense to me to stick with the matrix that I used to build the 
hlist and just work off of it to get both the number of list entries 
and 
text data for a given entry path.  The itemStyle suggestion provided 
exactly what I needed.  Thanks for taking to time to respond, it helped 
out alot.
