I am looking to write a GUI front end to what basically amounts to a "tail -f", however, I am not sure how to go about doing this. I would like to use a ListView object to highlight any lines that come through as "Failed", but i'm not sure how to go about updating the ListView with new information. Could someone please give me some insight as to how I could write this front end to use either the "tail -f" command or even the File::Tail module so that any changes are automagically updated in the ListView.
Thanks. Len.
