title: How to use QFileSystemWatcher to monitor a folder for change
body: <p>I'm new with QT and I want to use the QFileSystemWatcher to monitor a folder. I just can't figure how to do that.</p>
  
  <p>I read <a href="http://qt-project.org/doc/qt-4.8/qfilesystemwatcher.html">http://qt-project.org/doc/qt-4.8/qfilesystemwatcher.html</a> but I don't know how to even initialize it. </p>
  
  <p>I haven't found a single example, so now, I please if somebody could post an explanation or a simple example that monitors a folder and nothing more.</p>
  
  <p>Oh, and this is supposed to run in console if it matters.</p>
  
  <p>Thx for your answers and regards.</p>
