Overview of QtWebKit 2.1

UNDER CONSTRUCTION! This page is a draft that may still contain errors.

QtWebKit 2.1 is a web content engine based on the open source WebKit project. 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. As a general indicator of web compliance, QtWebKit passes all current ACID tests (1 to 3).

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 2.1 is an independent QtWebKit release that is not currently included in any Qt releases, so QtWebKit 2.1 is not covered by commercial Qt support from Nokia. QtWebKit 2.1 has been verified on Qt 4.7.


QtWebKit 2.1 runs on the following platforms:
