Qt - QFile - How to read only first word in every line

Question

How can I read only first word in every line in a text file while using QFile in Qt? Thanks.

Answer 1

use

    QFile ifile("in.txt");
    QString text = txStream.readLine();
    QStringList splitline = text.split(" ");
    QFile ofile("out.txt");
    ofile.open(QIODevice::WriteOnly | QIODevice::Text);

     QTextStream out(&ofile);

     // join QStringList by "\n" to write each single word in an own line
     out << splitline.join("\n");

     ofile.close();
