title: Need to save a new file with QFileDialog
body: <p>I am attempting to give the user an option of saving a file using QFileDialog
  However if the file does not exist the File Dialog states that the file does not exist.
  I want the QfileDialog to simply tell me the name of the file the user typed so that I can create it. I am doing the following</p>
  
  <pre><code>QFileDialog::getOpenFileNames(this, tr("Save File"))
  </code></pre>
  
  <p>and then create a file using the returned string.</p>
