title: PyQt QLineEdit with history
body: <p>Do you know an easy way to make an "history" on a QLineEdit in PySide/PyQt?</p>
  
  <p>Example: Whenever Enter is pressed, the typed text will be stored, and pressing the "up" or "down" arrows allows you to navigate through the history.</p>
  
  <p>Thank you very much</p>
