Qt / PyQt: How do I proceed with the QWebView / QWebPage "Open in new window" action?

If I have a QWebView open, I like its default context menu with "Open in new window" as an option for links. However, I cannot find a way to proceed when the user asks to open the link in a new window. Overriding the QWebPage.createWindow method doesn't seem to work because the method is not called when the user decides to open the link in a new window.

Any recommendations? I am using PyQt.

Sample code:

class LocalWebPage(QWebPage):
    def acceptNavigationRequest(self, webFrame, networkRequest, navigationType):
        print '*acceptNavigationRequest**',webFrame, networkRequest, navigationType
        return QWebPage.acceptNavigationRequest(self, webFrame, networkRequest, navigationType)

    def createWindow(self, windowType):
        print '--createWindow', windowType
        return QWebPage.createWindow(self, windowType)


class Browser(Ui_MainWindow, QMainWindow):
    def __init__(self, base, name):

        ...
        self.page = LocalWebPage()
        self.webViewMain = QWebView(self.centralwidget)
        self.webViewMain.setPage(self.page)
        ...

I have debug prints to check that createWindow is not being called.

You will need to call the method createWindow

for QWebView

yourself, for example, by overriding triggerAction

QWebPage

something like this:



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

from PyQt4 import QtGui, QtCore, QtWebKit

class MyPage(QtWebKit.QWebPage):
    def __init__(self, parent=None):
        super(MyPage, self).__init__(parent)

    def triggerAction(self, action, checked=False):
        if action == QtWebKit.QWebPage.OpenLinkInNewWindow:
            self.createWindow(QtWebKit.QWebPage.WebBrowserWindow)

        return super(MyPage, self).triggerAction(action, checked)


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

        self.myPage = MyPage(self)

        self.setPage(self.myPage)

    def createWindow(self, windowType):
        if windowType == QtWebKit.QWebPage.WebBrowserWindow:
            self.webView = MyWindow()
            self.webView.setAttribute(QtCore.Qt.WA_DeleteOnClose, True)

            return self.webView

        return super(MyWindow, self).createWindow(windowType)

if __name__ == "__main__":
    import sys

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

    main = MyWindow()
    main.show()
    main.load(QtCore.QUrl("http://www.example.com"))

    sys.exit(app.exec_())

The link that was right clicked can be found using hitTestContent

in the method contextMenuEvent

QWebView

:



def contextMenuEvent(self, event):
  pos = event.pos()
  element = self.page().mainFrame().hitTestContent(pos)
  link_url = str(element.linkUrl().toString())
