This type is made available by importing the \c QtWebKit module: \bold{import QtWebKit 1.0} The WebView item includes no scrolling, scaling, toolbars, or other common browser components. These must be implemented around WebView. See the \l{QML Web Browser} example for a demonstration of this. The page to be displayed by the item is specified using the \l url property, and this can be changed to fetch and display a new page. While the page loads, the \l progress property is updated to indicate how much of the page has been loaded. \section1 Appearance If the width and height of the item is not set, they will dynamically adjust to a size appropriate for the content. This width may be large for typical online web pages, typically greater than 800 by 600 pixels. If the \l{Item::}{width} or \l{Item::}{height} is explictly set, the rendered Web site will be clipped, not scaled, to fit into the set dimensions. If the preferredWidth property is set, the width will be this amount or larger, usually laying out the Web content to fit the preferredWidth. The appearance of the content can be controlled to a certain extent by changing the settings.standardFontFamily property and other settings related to fonts. The page can be zoomed by calling the heuristicZoom() method, which performs a series of tests to determine whether zoomed content will be displayed in an appropriate way in the space allocated to the item. \section1 User Interaction and Navigation By default, certain mouse and touch events are delivered to other items in preference to the Web content. For example, when a scrolling view is created by placing a WebView in a Flickable, move events are delivered to the Flickable so that the user can scroll the page. This prevents the user from accidentally selecting text in a Web page instead of scrolling. The pressGrabTime property defines the time the user must touch or press a mouse button over the WebView before the Web content will receive the move events it needs to select text and images. When this item has keyboard focus, all keyboard input will be sent directly to the Web page within. When the navigates by clicking on links, the item records the pages visited in its internal history Because this item is designed to be used as a component in a browser, it exposes \l{Action}{actions} for \l back, \l forward, \l reload and \l stop. These can be triggered to change the current page displayed by the item. \section1 Example Usage \beginfloatright \inlineimage webview.png \endfloat The following example displays a scaled down Web page at a fixed size. \snippet doc/src/snippets/declarative/webview/webview.qml document \clearfloat \sa {declarative/modelviews/webview}{WebView example}, {demos/declarative/webbrowser}{Web Browser demo} */ /*! \internal \class KDeclarativeWebView \brief The KDeclarativeWebView class allows you to add web content to a QDeclarativeView.
