title: PyQt5 - Python | QApplication.setStyle not working
body: <p>I am trying to set custom style to my PyQt5 application using the <code>setStyle()</code> method but it doesn't work.</p>
  
  <p>I am also not entirely sure about where this should be put.</p>
  
  <p>In my main I tried doing :</p>
  
  <pre><code>if __name__ == '__main__':
  
      QApplication.setStyle("mac") #here
      app = QApplication(sys.argv)
      splash_pix = QPixmap('../resource/logo.png')
      start = time.time()
      splash = QSplashScreen(splash_pix, Qt.WindowStaysOnTopHint)
      splash.show()
      while time.time() - start &lt; 1:
          time.sleep(0.003)
          app.processEvents()
      ex = Fy360()
      splash.finish(ex)
      sys.exit(app.exec_())
  </code></pre>
  
  <p>Edit : Upon importing <code>from PyQt5.QtWidgets import QStyleFactory</code> and printing the <code>QStyleFactory.keys()</code> I gotthe output as:</p>
  
  <p><code>[u'Windows', u'Fusion']</code></p>
  
  <p>why are there only these options?</p>
  
  <p><em>Whats going wrong here?</em></p>
