Overview of QtWebKit 2.2
QtWebKit is a web content engine based on the Open Source WebKit project, the same engine used by browsers such as ​Google Chrome and ​Safari from Apple. QtWebKit has broad support for modern web technologies and is compliant with typical web content. QtWebKit is developed as a part of the WebKit community, which enables every new release of QtWebKit to include the latest developments from the WebKit project.
QtWebKit has a C++ API that allows Qt applications to embed web content, and to examine and manipulate the web content. The QtWebKit C++ API is extensively documented in the QtWebKit documentation.
QtWebKit-2.2 was branched from the WebKit trunk on May of 2011 and includes several HTML5, CSS and JavaScript improvements when compared to QtWebKit-2.1 and QtWebKit-2.0 (see details below).
