title: How to show a small hovering non pop up message in PyQt
body: <p>What i want to achieve is something like <strong>toast messages</strong> in android . I don't want a message box to be displayed to the user with an overlaying window of its own. I just want to display a small message that tells the user that some process is done. The message involves no user interaction and is only there to notify the user while he is interacting with the other GUI elements . </p>
  
  <p>I have no idea how to do this in PyQt. Any help is greatly appreciated.</p>
