This article shows how to add proxy support at an application level using QNetworkProxy.

[edit] Introduction

Suppose you have an existing Qt application that makes use of QtNetwork classes. Qt let you specify a proxy for every connection you create, but there is simple way to set global proxy settings so the whole application will use those settings for any connection it will use.

[edit] Idea and implementation

You just need to insert this sample code in your main.cpp (please insert it right before return a.exec();) in the main(...) method. Of course in this way the proxy settings will be hardcoded, but you can always read/save them from a configuration file, using the QSettings class.

QNetworkProxy proxy;
proxy.setType(QNetworkProxy::HttpProxy);
proxy.setHostName("proxy.example.com");
proxy.setPort(1080);
proxy.setUser("username");
proxy.setPassword("password");
QNetworkProxy::setApplicationProxy(proxy);
