title: Automatically provide save file name?
body: <p>I am a bit new to using the GUI programming application PyQt4 and I had a question about saving files. </p>
  
  <p>Is there some sort of way to create a save file button on a PyQt4 application that doesn't require you to use the <code>QFileDialog.getSaveFileName(...)</code> function? I want to create a button that will allow you to save files without the user having to enter the name, but rather having it specified based on an already-decided filename that I would provide.</p>
  
  <p>I was trying to look at PyQt4 documentation that could do this but I couldn't find anything that would save files without using the <code>QFileDialog.getSaveFileName(...)</code> function.</p>
  
  <p>If anyone could help me out that would be great! </p>
  
  <p>Thanks.</p>
