title: PyQt implementing dialog icons
body: <p>Every OS has their own implementation of a file browser and, in PyQt, using QFileDialog will always show that OS's version. </p>
  
  <p>Some applications even have their own implementations of these windows and have their own back/forward/up button icons for those dialogs. Here are a couple examples:</p>
  
  <p>The Foundry Mari</p>

  <p>Autodesk Maya</p>

  <p>Both windows come up from the same code,</p>
  
  <pre><code>from PySide import QtGui
  QtGui.QFileDialog.getExistingDirectory(QtGui.QWidget(), "Select Directory"))
  </code></pre>
  
  <p>I'm assuming this is either because of a stylesheet that's being applied by the software (in this case, Maya or Mari) or some other implementation but the point is, I'm making an application where I'd like to utilize the same method. That way, no matter what application a user calls my GUI in, it'll always kind of look like what they're used to seeing in that particular software.</p>
