[PyQt] Issue of QWebPage.extension

Mon Jan 7 14:10:09 GMT 2013

Hello,

you have to cast it explicitly using sip.cast.

Here is a code extract of the eric5 web browser.

        if extension == QWebPage.ErrorPageExtension:
            info = sip.cast(option, QWebPage.ErrorPageExtensionOption)
            errorPage = sip.cast(output, QWebPage.ErrorPageExtensionReturn)

Regards,
Detlev

This need  reimplement  QWebPage.extension 
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qwebpage.html#extension, 
and get detail from the second argument ExtensionOption.

Code like this: 

    def extension(self, extension, info = None, errorPage = None):
        if extension == QtWebKit.QWebPage.ErrorPageExtension:
            content = u"<html><head><title>Failed loading 
page</title></head><body><h1>Failed loading page (%s)</h1><h2>%s</h2> 
</body></html>" % (info.errorString, info.url.toString())
            errorPage.content = QtCore.QByteArray(content.encode('utf-8'))
            gdata.log(u'Warn: Failed loading [%s] (%s)!' % (info.errorString, 
info.url.toString() ))
            return True
        return True

When extension == QtWebKit.QWebPage.ErrorPageExtension, the second argument 
should be QWebPage.ErrorPageExtensionOption, but it always 
be QWebPage.ExtensionOption, and can't get the detailed error message from it.

PySide has this problem in earlier versions, it be fixed later with test 
case http://pyside.sourcearchive.com/documentation/1.0.1-1/bug__694_8py_source.html 
. Hope PyQt can fix it.
