title: PyQt5 FileDialog: Show network folders
body: <p>My system is as follows: python 3.6.0 with PyQt 5.8.1 installed in an anaconda environment on ubuntu 16.10.</p>
  
  <p>I want to show/select network folders (connected via samba) with the PyQt5 FileDialog, but am unable to do so.
  In PyQt4 (another environment) it works.</p>
  
  <p>relevant code:
          from PyQt5 import QtWidgets
          fileDialog=QtWidgets.QFileDialog()
          workDirectory = str(fileDialog.getExistingDirectory(caption= "Set Work Directory", directory=defaultWorkDirectory))
          fileDialog.deleteLater()</p>
  
  <p>The PyQt5 documentation just leads to the C++ one and there is this about network/local files: "Note: The non-native QFileDialog supports only local files." and "When possible, this static function will use the native file dialog and not a QFileDialog. On platforms which don't support selecting remote files, Qt will allow to select only local files."
  I thought, ubuntu supports this (just like in PyQt4).</p>
  
  <p>Is there a way to do this or do i have to settle with PyQt4?</p>
  
  <p>Thanks,
  Topsrek</p>
