title: Reload webView widget automaticly with a loop and a timer
body: <p>I'm creating a GUI where I want to display a site with qWebView and reload it automaticly every 10 seconds.</p>
  
  <p>I tried with a qThread, no results. (I'm a new with threading)
  And if I use a normal while loop my window freeze.</p>
  
  <pre><code>from PyQt5 import QtCore, QtGui, QtWidgets, QtWebEngineWidgets
  
  class updator(QtCore.QThread):
      def __init__(self, window):
          QtCore.QThread.__init__(self)
  
  
      def run(self):
          while True:
              self.sleep(2000 * 2 / 1000)
              self.window.htmlreader_BTCLiveGraph.reload()
  
  class Ui_BTC_LiveGraph(object):
      def setupUi(self, BTC_LiveGraph):
          BTC_LiveGraph.setObjectName("BTC_LiveGraph")
          BTC_LiveGraph.resize(1600, 900)
          BTC_LiveGraph.setAccessibleDescription("")
          self.htmlreader_BTCLiveGraph = QtWebEngineWidgets.QWebEngineView(
              BTC_LiveGraph)
          self.htmlreader_BTCLiveGraph.setGeometry(
              QtCore.QRect(10, 10, 1500, 800))
          self.htmlreader_BTCLiveGraph.setAccessibleDescription("")
          # récupération du chemin absolu du fichier
          self.mypath = os.path.dirname(__file__)
          self.htmlreader_BTCLiveGraph.setUrl(QtCore.QUrl(
              str("file:///" + self.mypath + "/BTC_liveGraph.html")))
          self.htmlreader_BTCLiveGraph.setObjectName("htmlreader_BTCLiveGraph")
  
          self.retranslateUi(BTC_LiveGraph)
          QtCore.QMetaObject.connectSlotsByName(BTC_LiveGraph)
  
      def retranslateUi(self, BTC_LiveGraph):
          _translate = QtCore.QCoreApplication.translate
          BTC_LiveGraph.setWindowTitle(
              _translate("BTC_LiveGraph", "BTC Live Graph"))
  
  if __name__ == "__main__":
      import sys
      app = QtWidgets.QApplication(sys.argv)
      BTC_LiveGraph = QtWidgets.QDialog()
      ui = Ui_BTC_LiveGraph()
      ui.setupUi(BTC_LiveGraph)
      BTC_LiveGraph.show()
      update = updator(ui)
      update.start()
      sys.exit(app.exec_())
  </code></pre>
  
  <p>I would like the qwebviewWidget to reload every 10 seconds smouthly and having no freeze for the window</p>
