For example, you can do something like this: You can load generated HTML into it using the setHtml method. There are other interesting ways to load content into a QWebView. Equivalent would be to use the setUrl method, like so: That loads Python Central's main page in the QWebView control. The simplest - and possibly the most obvious - is its load method, which takes a QUrl the simplest way to construct a QUrl is with a unicode URL string: There are a number of ways to put content into it, however. You instantiate a QWebView like any othe QWidget, with an optional parent. Creating and Filling a QWebView Content from a QWebView's URL WebKit is an up-to-date, standards-compliant rendering engine used by Google's Chrome, Apple's Safari, and soon the Opera browser.

The QWebView is a highly useful control it allows you to display web pages from URLs, arbitrary HTML, XML with XSLT stylesheets, web pages constructed as QWebPages, and other data whose MIME types it knows how to interpret.
