title: QFileSystemModel and QFileSystemWatcher delete from disk
body: <p>I have a QTreeView which is populated through a reimplementation of QFileSystemModel. As far as I know, QFileSystemModel installs a QFileSystemWatcher on the rootPath. What I'm trying to do is notify in my program when a file is being deleted directicly on the rootPath but i havent found any signal o reimplemented function which provides me that information.</p>
  
  <p>My application upload some files thrugh an ftp connection and when the file is fully uploaded i remove it from the location, so i want a notification from the reimplementation of QFileSystemModel when the file is deleted directicly (not from the remove method or something similar).</p>
  
  <p>I Hope you can help me. I have searched a lot on the web but I cant find anything.</p>
  
  <p>Cheers.</p>
