    I want to count number of rows in a selected file. I also need to do it with QFile and QDir.
    Thanks for your help.

      Assuming by "rows" you mean "lines". Open the file for text read, use QFile::readline() to read lines, count as you go?

        why do something programatically that already exists in command line utils?

        wc -l file

        but I digres since these kind of questions often indicate a sub-optimal file IO paradigm like line based file records. Bleck!

        If you meet the AI on the road, kill it.
