title: PyQt icons missing?
body: <p>I am new to PyQt and I am learning to make GUIs based on online tutorials I found. One of the examples in the tutorials uses an icon, here is the code from the tutorial:</p>
  
  <pre><code>import sys
  from PyQt5.QtWidgets import QMainWindow, QAction, qApp, QApplication
  from PyQt5.QtGui import QIcon
  
  class Example(QMainWindow):
  
      def __init__(self):
          super().__init__()
  
          self.initUI()
  
  
      def initUI(self):               
  
          exitAct = QAction(QIcon('exit24.png'), 'Exit', self)
          exitAct.setShortcut('Ctrl+Q')
          exitAct.triggered.connect(qApp.quit)
  
          self.toolbar = self.addToolBar('Exit')
          self.toolbar.addAction(exitAct)
  
          self.setGeometry(300, 300, 300, 200)
          self.setWindowTitle('Toolbar')    
          self.show()
  
  
  if __name__ == '__main__':
  
      app = QApplication(sys.argv)
      ex = Example()
      sys.exit(app.exec_())
  </code></pre>
  
  <p>The output according to the tutorial should be</p>
  
  <p><a href="https://i.stack.imgur.com/0tBPl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0tBPl.png" alt="enter image description here"></a>

  As I said, I just started with PyQt and I just installed PyQt through pip</p>
  
  <pre><code>pip install PyQt5
  </code></pre>
  
  <p>I'm using Python3.6 and PyQt5. Any help is greatly appreciated!</p>
