title: Serving resource to QWebView of PyQT5
body: <p>How can serve resource (files like html, css, js, fonts) for a desktop app to QWebView (in PyQT5)?</p>
  
  <p>What I want is:</p>
  
  <ol>
  <li>If possible handling requested resource by Webkit engine of PyQT5
  with a custom scheme like say <code>custom://app/jquery.js</code> and returning the file.</li>
  <li>If possible handling standard http verbs (GET, POST, ...) for that
  custom scheme.</li>
  </ol>
  
  <p>If these 2 are not possible (at least not possible in a pure Pythonic way):</p>
  
  <ul>
  <li>How can I intercept requests coming from the embedded Webkit and
  provide resource (html, css, js) based on a pattern in url (like say
  some regex <code>(?&lt;controller&gt;[^/])/(?&lt;action&gt;[^/])</code>)?</li>
  </ul>
