Overview

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

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

  • Not implemented: implementation for the feature does not exist
  • Technology preview: the implementation of the feature is ready for experimentation and validation, but not for production use. The implementation may be incomplete and there may be known problems.
  • Experimental: the implementation of the feature can 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.
