    Description

      The examples in the QtConcurrentRun documentation 'Using member functions' have errors (http://doc.qt.nokia.com/4.7/qtconcurrentrun.html#using-member-functions).

      The example of calling QByteArray::split() has an extra bracket. It would also be nice for the split to actually happen (the bytearray would have a comma). This would work:

          QByteArray bytearray = "hello, world";
          QFuture<QList<QByteArray> > future = QtConcurrent::run(bytearray, &QByteArray::split, ',');
          ...
          QList<QByteArray> result = future.result();
      

      The example of calling QImage::invertPixels is not doing anything to the image right now. A reference to the image should be given for the QtConcurrent::run:

          QImage image = ...;
          QFuture<void> future = QtConcurrent::run(&image, &QImage::invertPixels, QImage::InvertRgba);
          ...
          future.waitForFinished();
