opening webpage using qt....

[anupamgee]

hi all,
I hv some problem in opening the webpage using qtwebkit module..
I am using internet in a NAT environment.
i used the following code:

Widget::Widget(QWidget *parent): QWidget(parent)
{
      QNetworkProxy proxy;
        proxy.setHostName("10.8.58.40");
       proxy.setPort(8080);
        QNetworkAccessManager *manager=new QNetworkAccessManager(this);
        manager->setProxy(proxy);
        QUrl url;
        url.setUrl("http://www.google.co.in");
        QWebPage *page=new QWebPage();
        page->mainFrame()->load(url);
        QWebView *view = new QWebView(this);
        view->setPage(page);
        view->show();
}

Widget::Widget(QWidget *parent): QWidget(parent)
{
      QNetworkProxy proxy;
        proxy.setHostName("10.8.58.40");
       proxy.setPort(8080);
        QNetworkAccessManager *manager=new QNetworkAccessManager(this);
        manager->setProxy(proxy);
        QUrl url;
        url.setUrl("http://www.google.co.in");
        QWebPage *page=new QWebPage();
        page->mainFrame()->load(url);
        QWebView *view = new QWebView(this);
        view->setPage(page);
        view->show();
}

To copy to clipboard, switch view to plain text mode

You are created a network access manager and setting a proxy on it but QWebView never uses this object so it doesn't pick up the proxy. I'd try with QNetworkProxy::setApplicationProxy instead.

Thanx for reply .
can u explain this with the help of code .As i hv tried this also but didnt work for me .

[wysota]

I have a better idea - you explain what you did in code and I'll say what you did wrong (if anything).

hi,

i used this code:

#include <QApplication>
#include <QWebView>

int main(int argc, char **argv)
{
QApplication app(argc, argv);

QWebView *view = new QWebView();
view->load(QUrl("http://www.webstandards.org/files/acid2/test.html"));
view->show();

return app.exec();
}

but it is not showing the webpage.it is showing an empty widget.I want to change the proxy settings .

i used QNetworkProxy::setApplicationProxy() also. but still code doesn't work..

Widget::Widget(QWidget *parent): QWidget(parent)
{
QNetworkProxy proxy;
proxy.setType(QNetworkProxy::HttpProxy);
proxy.setHostName("10.8.58.40");
proxy.setPort(8080);
QNetworkProxy::setApplicationProxy(proxy);
QWebView *web=new QWebView();
web->load(QUrl("http://www.google.com"));
web->show();
}

Which version of Qt do you use? Releases earlier than 4.5.0 don't use applicationwide proxy settings for WebKit. It should work in 4.5.0 (at least it had been said it would work).

but still it is not working.....
