Cannot load HTML file with QWebEngineView.setHtml()
Question
The solution of my problem is probably very simple but yet out of my understanding. I am trying to load an HTML file into a QWebEngineView with PyQt5. The way I am doing it is:
self.webView = QtWebEngineWidgets.QWebEngineView(self.splitter)
html = r"C:\DATI\git\webgis\map.html"
self.webView.setHtml(html)
The only thing I get is a string representing the path and name of my HTML file:
C:\\DATI\\git\\webgis\\map.html
My map.html looks like this:
<html>
<head>
<title>Simple Map</title>
<link rel="stylesheet" href="https://openlayers.org/en/v4.5.0/css/ol.css" type="text/css">
<!-- The line below is only needed for old environments like Internet Explorer and Android 4.x -->
<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=requestAnimationFrame,Element.prototype.classList,URL"></script>
<script src="https://openlayers.org/en/v4.5.0/build/ol.js"></script>
<script src=".js/qwebchannel.js"></script>
<style>
body { padding: 0; margin: 0; }
html, body, #map { height: 100%; }
</style>
</head>
<body>
<div id="map" class="map"></div>
<script src="./js/map.js"></script>
</body>
</html>
Strangely (to me at least), if I do self.webView.setHtml("<html><head></head><body><h1>ciao</h1></body></html>") , this will render the HTML properly.
What am I missing?

The setHtml method does exactly what its name suggests: it loads html content from a string. What you are trying to do is load a url , so for that, you need to use the load method :
url = QtCore.QUrl.fromLocalFile(r"C:\DATI\git\webgis\map.html")
self.webView.load(url)
