This property holds the location of the currently displaying web site icon, also known as favicon or shortcut icon. This read-only URL corresponds to the image used within a mobile browser application to represent a bookmarked page on the device's home screen.

The following snippet uses the icon property to build an Image component:

Image {
    id: appIcon
    source: webView.icon != "" ? webView.icon : "fallbackFavIcon.png";
    ...
}

Returns true if the web view is in fullscreen mode, false otherwise.

This QML property was introduced in QtWebEngine 1.1.

See also WebEngineView::fullScreenRequested and WebEngineView::fullScreenCancelled.

This property holds the amount of the page that has been loaded, expressed as an integer percentage in the range from 0 to 100.

Returns true if the HTML page is currently loading, false otherwise.

The navigation history of the current view.

This QML property was introduced in QtWebEngine 1.1.

See also WebEngineHistory.

The current profile used for the view.

This QML property was introduced in QtWebEngine 1.1.

See also WebEngineProfile.

Settings used by this view.

This QML property was introduced in QtWebEngine 1.1.

See also WebEngineSettings.

This property holds the title of the currently displaying HTML page, a read-only value that reflects the contents of the <title> tag.

The location of the currently displaying HTML page. This writable property offers the main interface to load a page into a web view. It functions the same as the window.location DOM property.

See also WebEngineView::loadHtml().

List of script objects attached to the view.

The web channel instance used by this view. This channel is automatically using the internal QtWebEngine transport mechanism over Chromium IPC, and exposed in the javascript context of the page it is rendering as qt.webChannelTransport. This transport object is used when instantiating the JavaScript counterpart of QWebChannel using the Qt WebChannel JavaScript API.

Note: The view does not take ownership for an assigned webChannel object.

This QML property was introduced in QtWebEngine 1.1.

Zoom factor for the view. Valid values are within the range from 0.25 to 5.0. The default factor is 1.0.

This QML property was introduced in QtWebEngine 1.1.

This signal is emitted when an invalid certificate error is raised while loading a given request.

The certificate error can be rejected by calling WebEngineCertificateError::rejectCertificate, which will stop loading the request.

The certificate error can be ignored by calling WebEngineCertificateError::ignoreCertificateError which will resume loading the request.

It is possible to defer the decision of rejecting the given certificate by calling WebEngineCertificateError::defer, which is useful when waiting for user input. By default the invalid certificate will be automatically rejected.

The corresponding handler is onCertificateError.

This QML signal was introduced in QtWebEngine 1.1.

See also WebEngineCertificateError.

This is signal is emitted when the web site identified by securityOrigin requests to make use of the resource or device identified by feature.

See also WebEngineView::grantFeaturePermission.

This signal is emitted when the web page requests fullscreen mode through the JavaScript API.

The corresponding handler is onFullScreenRequested.

This QML signal was introduced in QtWebEngine 1.1.

See also WebEngineFullScreenRequest and WebEngineView::isFullScreen.

This signal is emitted when a JavaScript program tries to print a message to the web browser's console.

For example in case of evaluation errors the source URL may be provided in sourceID as well as the lineNumber.

level indicates the severity of the event that triggered the message, i.e. if it was triggered by an error or a less severe event.

The corresponding handler is onJavaScriptConsoleMessage.

Within a mouse-driven interface, this signal is emitted when a mouse pointer passes over a link, corresponding to the mouseover DOM event. This event may also occur in touch interfaces for mouseover events that are not cancelled with preventDefault(). hoveredUrl provides the link's location.

The corresponding handler is onLinkHovered.

This signal is emitted when a page load begins, ends, or fails. The corresponding handler is onLoadingChanged.

When handling the signal with onLoadingChanged, various read-only parameters are available on the loadRequest:

See also WebEngineView::loading.

This signal is emitted when a page load is requested to happen in a separate WebEngineView. This can either be because the current page requested it explicitly through a JavaScript call to window.open, or because the user clicked on a link while holding Shift, Ctrl or a built-in combination that triggers the page to open in a new window.

If this signal isn't handled the requested load will fail.

An example implementation:

QtObject {
    id: windowParent
    // Create the initial browsing windows and open the startup page.
    Component.onCompleted: {
        var firstWindow = windowComponent.createObject(windowParent)
        firstWindow.webView.loadHtml('<input type="button" value="Click!" onclick="window.open(&quot;http://qt.io&quot;)">')
    }

    property Component windowComponent: Window {
        // Destroy on close to release the Window's QML resources.
        // Because it was created with a parent, it won't be garbage-collected.
        onClosing: destroy()
        visible: true

        property WebEngineView webView: webView_
        WebEngineView {
            id: webView_
            anchors.fill: parent

            // Handle the signal. Dynamically create the window and
            // use its WebEngineView as the destination of our request.
            onNewViewRequested: {
                var newWindow = windowComponent.createObject(windowParent)
                request.openIn(newWindow.webView)
            }
        }
    }
}

The corresponding handler is onNewViewRequested.

This QML signal was introduced in QtWebEngine 1.1.

See also WebEngineNewViewRequest, WebEngineView::NewViewDestination, and WebEngine Quick Nano Browser.

Finds the specified string, subString, in the page, using the given options.

To clear the selection, just pass an empty string.

The resultCallback must take a boolean parameter. It will be called with a value of true if the subString was found; otherwise the callback value will be false.

findText("Qt", WebEngineView.FindCaseSensitively, function(success) {
    if (success)
        console.log("Qt was found!");
});

This QML method was introduced in QtWebEngine 1.1.

Finds the specified string, subString, in the page, using the given options.

To clear the selection, just pass an empty string.

findText("Qt", WebEngineView.FindBackward | WebEngineView.FindCaseSensitively);

This QML method was introduced in QtWebEngine 1.1.

Finds the specified string, subString, in the page.

To clear the selection, just pass an empty string.

This QML method was introduced in QtWebEngine 1.1.

Immediately sets isFullScreen property to false. It can be used to notify the browser engine when the windowing system forces the application to leave fullscreen mode.

ApplicationWindow {
    onVisibilityChanged: {
        if (webEngineView.isFullScreen && visibility != Window.FullScreen)
            webEngineView.fullScreenCancelled()
    }

    WebEngineView {
        id: webEngineView
        ...
    }
}

This QML method was introduced in QtWebEngine 1.1.

See also WebEngineView::isFullScreen and WebEngineView::fullScreenRequested.

Go backward within the browser's session history, if possible. This function is equivalent to the window.history.back() DOM method.

See also WebEngineView::canGoBack.

If offset is positive, goes forward the specified number of offset pages in the current session history. If offset is negative, it goes back. If the offset is invalid, the page is not changed.

This QML method was introduced in QtWebEngine 1.1.

See also WebEngineView::goBack and WebEngineView::goForward.

Go forward within the browser's session history, if possible. This function is equivalent to the window.history.forward() DOM method.

Sets the permission for the web site identified by securityOrigin to use feature.

This QML method was introduced in QtWebEngine 1.1.

See also WebEngineView::featurePermissionRequested.

Loads the specified html as the content of the web view.

This method offers a lower-level alternative to the url property, which references HTML pages via URL.

External objects such as stylesheets or images referenced in the HTML document should be located relative to baseUrl. For example, if html is retrieved from http://www.example.com/documents/overview.html, which is the base url, then an image referenced with the relative url, diagram.png, should be at http://www.example.com/documents/diagram.png.

See also WebEngineView::url.

Reloads the current page. This function is equivalent to the window.location.reload() DOM method.

See also WebEngineView::reloadAndBypassCache.

Reloads the current page, ignoring any cached content.

See also WebEngineView::reload.

Runs the specified script in the content of the web view.

In case a callback function is provided it will be invoked after the script finished running.

runJavaScript("document.title", function(result) { console.log(result); });

Stops loading the current page.
