Hello,

I have implemented a list using TkText that holds a list of sales tax  
rates.  
I am comparing this list to a list of other rates, which is also  
implemented  
via a TkText widget. I was wondering how to highlight the rates (using a  
different color) in the list that differ from the rates in the other  
list. I  
am aware of TkList, but did not want to go that route on this project.

Any help would be appreciated.

Thank You,

Harry

Please use TkTextTag.  
You can find examples using TkTextTag on “/ext/tk/sample/\*”.  
“/ext/tk/sample/tkmulticolumnlist.rb” may be a useful example  
for your purpose.

Or, do you want any other one?
