title: Qt - Selecting multiple folders/directories using a dialog
body: <p>I want to achieve something like the following:</p>
  
  <p><img src="https://i.stack.imgur.com/Ocgks.png" alt="enter image description here"></p>
  
  <p>Where I can select multiple folders across multiple drives and retrieve the folder paths of those selected.  Qt only has a crude multi-folder selection feature, but it does not support selected folders from other drives etc.</p>
  
  <p>Can anyone guide me on how to create such a dialog?  Better yet, does any one have any sample code I could use (this is an extension to an old project, and I'd much rather save my time and not re-invent the wheel!)</p>
  
  <p>Thanks </p>
