Hi guys,

I am using evaluateJavaScript to change some JS values in my case
window.navigator. It works pretty well on first visited page
http://something.tld/first.php but when I click on any link on that page
and go to second.php it stops to be in effect.
How can I do it to stay this javascript in effect for every visited
(navigated, clicked) page from my application?

#!/usr/bin/env python
#-*- coding:utf-8 -*-

from PyQt4 import QtCore, QtGui, QtWebKit

getJsValue = """
window.navigator = {
  appCodeName: 'MyApp',
  appName: 'MyNewApp',
  vendor: 'MyCompany'
}
"""

class myWindow(QtWebKit.QWebView):
    def __init__(self, parent=None):
        super(myWindow, self).__init__(parent)

        self.page().mainFrame().evaluateJavaScript(getJsValue)

        self.page().mainFrame().addToJavaScriptWindowObject("myWindow",
self)
        self.loadFinished.connect(self.on_loadFinished)
        self.load(QtCore.QUrl('http://something.tld/first.php'))

    @QtCore.pyqtSlot(str)
    def showMessage(self, message):
        print "Message from website:", message

    @QtCore.pyqtSlot()
    def on_loadFinished(self):
        #self.page().mainFrame().evaluateJavaScript(getJsValue)
        pass

if __name__ == "__main__":
    import sys

    app = QtGui.QApplication(sys.argv)
    app.setApplicationName('myWindow')

    main = myWindow()
    main.show()

    sys.exit(app.exec_())
