How use different proxies for each QTwebview browser control in an application ?

Zain

Hello All,

I am developing an application that opens some sites on different-different QTwebview browser controls(for example 4 QTwebview browser).

Is it possible to use different proxy with each QTwebview browser ?

I am using below code to use proxy :-

@QNetworkProxy proxy;
proxy.setType(QNetworkProxy::HttpProxy);
proxy.setHostName(proxyName);
proxy.setPort(8080);
QNetworkProxy::setApplicationProxy(proxy);@

Thanks in advance
Zain

You can obtain the "QWebPage":http://qt-project.org/doc/qt-5.0/qtwebkit/qwebpage.html from your "QWebView":http://qt-project.org/doc/qt-5.0/qtwebkit/qwebview.html using method page() and then to change the network access manager of the "QWebPage":http://qt-project.org/doc/qt-5.0/qtwebkit/qwebpage.html using method "setNetworkAccessManager":http://qt-project.org/doc/qt-5.0/qtwebkit/qwebpage.html#setNetworkAccessManager. Please note the remark at the documentation:

bq. Note: It is currently not supported to change the network access manager after the QWebPage has used it. The results of doing this are undefined.

So it is a tricky and as you said you should try using separate QWebViews with separate QWebPages and separate "QNetworkAccessManagers":http://qt-project.org/doc/qt-5.0/qtnetwork/qnetworkaccessmanager.html

OK, I forgot to note that you should call method "setProxy":http://qt-project.org/doc/qt-5.0/qtnetwork/qnetworkaccessmanager.html#setProxy to specify which proxy should your network access manager use.

Thanks for the tip.

Just for your information, here I am talking about more than 1 proxy at a time!!

Just wondering is it possible in QT ?

Thanks

Yes, I understand you. As I noted in my previous post at the moment it is not possible to change the proxy after the QWebPage has already used it but you can try to use separate instances of QWebViews and QWebPages.
