Feature documentation for QtWebKit 2.0

NOTE: This is page is incomplete and under construction. These tables will be moved to QtWebKit documentation.

Overview

QtWebKit 2.0 is a web content engine based on the Open Source WebKit engine.

High-level list of supported standards:

  • HTML 4.01, partial and experimental support for upcoming HTML 5
  • XHTML 1.0
  • CSS 2.1 and partial and experimental support for upcoming CSS3
  • ECMAScript 3 (JavaScript)
  • DOM Level 2
  • AJAX technologies, including XMLHTTPRequest
  • XHTML / MP support

This documentation uses the following classification for the levels of support:

  • Not implemented: implementation for the feature does not exist or is so incomplete that even validation and experimentation is not recommended
  • Technology preview: the implementation of the feature is available for experimentation and validation, but not recommended for production use. The implementation may be incomplete and there may be known problems.
  • Experimental: the implementation of the feature is ready to be used in production applications with the caveat that the API, standard or the implementation may be still change in future releases, or there may be some limitations in the implementation.
  • Supported: the feature has been implemented and verified, and we don't expect changes in the API or standard.

  • Linux on x86 platforms with gcc 4.1 or higher
  • Linux on ARM (Thumb-2 JIT is not currently used)

HTML5 canvas and media

Feature Status Layout test
<canvas> element Technology preview (partial support). LayoutTests/fast/canvas
WebGL 3D canvas Technology preview (partial support)

QtWebKit has had experimental support for HTML5 media via the Phonon multimedia integration since Qt 4.5. As of QtWebKit 2.0, we have added integration to the new QtMultimedia framework in Qt 4.7. In the future, improvements and new development will focus on the QtMultimedia framework based architecture.
