Widget that is used to view and edit web documents
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.
In addition to providing pure rendering features, HTML documents can be made fully editable to the user through the use of the
contenteditable attribute on HTML elements.
Including In Your Project
To include the definitions of the module's classes, use the following directive:
To link against the module, add this line to your qmake
QT += webkit
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 only in release mode for embedded platforms. Currently QtWebKit will always be compiled without debugging symbols when using gcc. Take a look at the last lines of
src/3rdparty/webkit/Source/WebCore/WebCore.pro if you need to change this.
Note: Web site icons, also known as "FavIcons", are currently not supported on Windows. We plan to address this in a future release.
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.
QWebView is used to view Web pages. An instance of QWebView has one QWebPage. 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.
Common web 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.
Netscape Plugin Support
Note: Netscape plugin support is only available on desktop platforms.
Since WebKit supports the Netscape Plugin API, Qt applications can display Web pages that embed common plugins on platforms for which those plugins are available. To enable plugin support, the user must have the appropriate binary files for those plugins installed and the QWebSettings::PluginsEnabled attribute must be enabled for the application.
The following locations are searched for plugins:
