- \brief An introduction to the QtWebKit module.
-
- \keyword Browser
- \keyword Web Browser
-
- \since 4.4
-
- QtWebKit provides a Web browser engine that makes it easy to embed content
- from the World Wide Web into your Qt application. At the same time Web
- content can be enhanced with native controls.
-
- QtWebKit provides facilities for rendering of HyperText Markup Language
- (HTML), Extensible HyperText Markup Language (XHTML) and Scalable Vector
- Graphics (SVG) documents, styled using Cascading Style Sheets (CSS) and
- scripted with JavaScript.
-
- A bridge between the JavaScript execution environment and the Qt object
- model makes it possible for custom QObjects to be scripted. Integration
- with the Qt networking module enables Web pages to be transparently loaded
- from Web servers, the local file system or even the Qt resource system.
-
- In addition to providing pure rendering features, HTML documents can be
- made fully editable to the user through the use of the \c{contenteditable}
- attribute on HTML elements.
-
- QtWebKit is based on the Open Source WebKit engine. More information about
- WebKit itself can be found on the \l{WebKit Open Source Project} Web site.
-
- The QtWebKit module is part of the \l{Qt Full Framework Edition}, and the
- \l{Open Source Versions of Qt}.
-
- \note Building the QtWebKit module with debugging symbols is problematic
- on many platforms due to the size of the WebKit engine. We recommend
- building the module in release mode only for embedded platforms.
-
- \note Web site icons, also known as "FavIcons", are currently not supported
- on Windows. We plan to address this in a future release.
-
- \note WebKit has certain minimum requirements that must be met on
- Embedded Linux systems. See the \l{Qt for Embedded Linux Requirements}
- document for more information.

- \section1 Configuring the Build Process
-
- Applications that use QtWebKit's classes need to be configured to be built
- against the QtWebKit module. The following declaration in a \c qmake
- project file ensures that an application is compiled and linked
- appropriately:
-
- \snippet doc/src/snippets/code/doc_src_qtwebkit.qdoc 0
-
- This line is necessary because only the QtCore and QtGui modules are used
- in the default build process.
-
- To include the definitions of the module's classes, use the following
- directive:
-
- \snippet doc/src/snippets/code/doc_src_qtwebkit.qdoc 1
-
- \section1 Architecture
-
- The easiest way to render content is through the QWebView class. As a
- widget it can be embedded into your forms or a graphics view, and it
- provides convenience functions for downloading and rendering web sites.
-
- \snippet snippets/webkit/simple/main.cpp Using QWebView
-
- QWebView acts as a view onto Web pages, each of which is represented by an
- instance of the QWebPage class. QWebPage provides access to the document
- structure in a page, describing features such as frames, the navigation
- history, and the undo/redo stack for editable content.
-
- HTML documents can be nested using frames in a frameset. An individual
- frame in HTML is represented using the QWebFrame class. It includes the
- bridge to the JavaScript window object and can be painted using QPainter.
- Each QWebPage has one QWebFrame object as its main frame.
-
- Individual browser features, defaults and other settings can be configured
- through the QWebSettings class. It is possible to provide defaults for all
- QWebPage instances through the default settings. Individual attributes
- can be overidden by the page specific settings object.
-
- \section1 Netscape Plugin Support
-
- Since WebKit supports the Netscape Plugin API, Qt applications can display
- Web pages that embed common plugins, as long as the user has the appropriate
- binary files for those plugins installed.
-
- The following locations are searched for plugins:
-
- \table
- \header \o Linux/Unix \o Windows
- \row \o{1,3}
- \list
- \o \c{.mozilla/plugins} in the user's home directory
- \o \c{.netscape/plugins} in the user's home directory
- \o System locations, such as
- \list
- \o \c{/usr/lib/browser/plugins}
