## Detailed Description

The WebEngineView type enables QML applications to render regions of dynamic web content. It may share the screen with other QML types, such as a TabView, or fill the screen, as specified within the QML application.

### Initializing Web Engine

For the web engine view to be rendered, the web engine must be initialized by using QtWebEngineQuick::initialize in the application main source file, as illustrated by the following code snippet:

     int main(int argc, char *argv[])
     {
         QCoreApplication::setAttribute(Qt::AA_ShareOpenGLContexts);
         QtWebEngineQuick::initialize();
         QGuiApplication app(argc, argv);
         QQmlApplicationEngine engine;
         engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
         return app.exec();
     }

### Loading Web Pages

An application can load pages into the WebEngineView, using either the url property or the loadHtml method and navigate within the view's session history. The GET method is always used to load URLs.

The history is represented by a WebEngineHistory data model that is held by the history property.

The following sample QML application loads a web page using the `url` property:

     import QtQuick
     import QtQuick.Window
     import QtWebEngine

     Window {
         width: 1024
         height: 750
         visible: true
         WebEngineView {
             anchors.fill: parent
             url: "https://www.qt.io"
         }
     }

The loading property holds whether an HTML page is currently loading. The loadingChanged() signal is emitted when loading the page begins, ends, or fails.

The title of an HTML page can be accessed with the title property. Additionally, a web page may specify an icon, which can be accessed using the icon property. The zoomFactor property enables zooming the contents of the web page by a scale factor.

If a certificate error is raised while loading a web page, the certificateError() signal is emitted. Certificate errors are handled by using the methods of the WebEngineCertificateError type.

### Interaction

By default, links to different pages load within the same WebEngineView object, but web sites may request them to be opened as a new tab, window, or dialog. The newWindowRequested() signal is emitted when a request to load the page in a separate web engine view is issued. The NewViewDestination property describes how the new view should be opened. In addition, the WebEngineNewWindowRequest utility type can be used to load web pages in separate web engine views.

The findText() method can be used to search for a string on a web page, using the options described by FindFlags.

The setActiveFocusOnPress() method can be used to create a UI element that should not get focus on press. This can be useful in a hybrid UI.

The focusOnNavigationEnabled setting can be used to make the view automatically receive focus when a navigation operation occurs (like loading or reloading a page or navigating through history).

The linkHovered() signal is emitted when a mouse pointer passes over a link and thus corresponds to the `mouseover` DOM event.

Actions, such as selecting and editing content, can be performed on a web page by using the triggerWebAction() method. The available actions are described by the WebAction property.

The backgroundColorChanged() signal is emitted when the web page background color changes.

### User Scripts

During the loading of a page, so called user scripts can be injected in the JavaScript engine at different points. The script objects attached to the web engine view are held by the userScripts property and injected by using the WebEngineScript type. Scripts can also be run by using the runJavaScript() method in the same world as other scripts that are part of the loaded site.

The webChannel property can be used to expose a WebChannel instance in the JavaScript context of the page it is rendering as `qt.webChannelTransport`.

### Fullscreen Mode

A web page can request through the JavaScript API to be loaded in fullscreen mode. The fullScreenRequested() signal is emitted when the web page issues the request. The FullScreenRequest utility type can be used to toggle fullscreen requests. The fullScreenCancelled method can be used to notify the browser engine when the windowing system forces the application to leave fullscreen mode.

### Profiles

Web engine views can be isolated from each other by using the WebEngineProfile type. A profile contains settings, scripts, and the list of visited links shared by all views that belong to the profile. For example, a dedicated profile could be created for a private browsing mode. The current profile for the view is held by the profile property and the current settings are held by the settings property. The settings are specified by using the WebEngineSettings type.

### Platform Features

Web pages can request access to platform features, such as geolocation or audio and video capture devices. The featurePermissionRequested() signal is emitted when a web page requests to make use of a resource. The supported platform features are described by the Feature property. If users grant the permission, the grantFeaturePermission() method is used to set it to granted.

### Rendering to OpenGL Surface

When using a QQuickRenderControl to render a Qt Quick user interface to an OpenGL surface, the WebEngineView type is not rendered correctly. The web engine view attempts to use a global OpenGL context created by QtWebEngineQuick::initialize, but there is no public API for accessing that context in order to share it with the `QQuickRenderControl` context.

To have the web engine view rendered correctly, it is possible to manually create a new offscreen context that is shared with the `QQuickRenderControl` and to call the non-public function `qt_gl_set_global_share_context()`, rather than calling `initialize()`. If `initialize()` is called after setting a global context, it will do nothing.

This property was introduced in QtWebEngine 1.2.

[since QtWebEngine 1.2] activeFocusOnPress : bool

Specifies whether the view should gain active focus when pressed. The default value is `true`.

This property was introduced in QtWebEngine 1.2.

[since QtWebEngine 1.3] audioMuted : bool

The state of whether the current page audio is muted.

This property was introduced in QtWebEngine 1.3.

See also recentlyAudible.

[since QtWebEngine 1.2] backgroundColor : color

Changes the color of the WebEngineView's background, behind the document's body. Can be set to `"transparent"` or to a translucent color to see through the document or to match the web content in a hybrid app to prevent the white flashes that may appear during loading.

The default value is white.

This property was introduced in QtWebEngine 1.2.

[read-only] canGoBack : bool

Returns `true` if there are prior session history entries, `false` otherwise.

[read-only] canGoForward : bool

Returns `true` if there are subsequent session history entries, `false` otherwise.

[read-only, since QtWebEngine 1.3] contentsSize : size

Size of the page contents.

This property was introduced in QtWebEngine 1.3.

[since QtWebEngine 1.7] devToolsView : WebEngineView

The view currently hosting the developer tools for this view. Setting it to a new view will navigate that view to an internal URL with the developer tools, and bind it to this view.

This property was introduced in QtWebEngine 1.7.

See also inspectedView.

[read-only, since QtWebEngine 1.1] history : WebEngineHistory

The navigation history of the current view.

This property was introduced in QtWebEngine 1.1.

See also WebEngineHistory.

[read-only] icon : url

An internal URL for accessing the currently displayed 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
         sourceSize: Qt.size(32, 32)
         source: webView.icon != "" ? webView.icon : "fallbackFavicon.png";
         // ...
     }

Specifying the Image::sourceSize property informs the Qt WebEngine's favicon provider about the requested size and resizes the icon to it. If Image::sourceSize property is not specified, the provider provides the icon with the largest available resolution.

[since QtWebEngine 1.7] inspectedView : WebEngineView

The view this view is currently inspecting, if any. Setting it will navigate to an internal URL with the developer tools of the view set.

It is recommended to unset this property when developer tools are not visible; otherwise some debug information may appear in the inspected WebEngineView.

This property was introduced in QtWebEngine 1.7.

See also devToolsView.

[read-only, since QtWebEngine 1.1] isFullScreen : bool

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

This property was introduced in QtWebEngine 1.1.

See also fullScreenRequested() and fullScreenCancelled().

[since QtWebEngine 1.10] lifecycleState : LifecycleState

The current lifecycle state of the page.

The following restrictions are enforced by the setter:

- A visible page must remain in the `Active` state.
- If the page is being inspected by a devToolsView then both pages must remain in the `Active` states.
- A page in the `Discarded` state can only transition to the `Active` state. This will cause a reload of the page.

These are the only hard limits on the lifecycle state, but see also recommendedState for the recommended soft limits.

This property was introduced in QtWebEngine 1.10.

See also recommendedState, Page Lifecycle API, and WebEngine Lifecycle Example.

[read-only] loadProgress : int

The amount of data from the page that has been loaded, expressed as an integer percentage in the range from `0` to `100`.

[read-only] loading : bool

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

[since QtWebEngine 1.1] profile : WebEngineProfile

The current profile used for the view.

[read-only] title : string

The title of the currently displayed HTML page. This is a read-only value that reflects the contents of the `<title>` tag.

[since QtWebEngine 6.4] touchHandleDelegate : Component

The touchHandleDelegate provides a template defining visual touch handles instantiated by the view whenever touch selection handling is required.

The handle's position, opacity, and visibility are updated automatically. The delegate should be a QML Item or any QML type which inherits it.

Note: If no QML Item is set, the default touch handles will be shown.

The following code uses a custom touch handle delegate:

     WebEngineView {
     // ...
         touchHandleDelegate: Rectangle {
             color: "red"
         }
         // ...
     }

The touch handles can be also switched dynamically:

      Component {
         id: circleTouchHandle
         Rectangle {
             color: "blue"
             radius: 50
         }
     }
     function showDefaultHandle(isDefault) {
         if (isDefault)
             webEngineView.touchHandleDelegate = circleTouchHandle
         else
             webEngineView.touchHandleDelegate = null
     }

Note: If no delegate is provided, Chromium's default touch handles will appear.

This property was introduced in QtWebEngine 6.4.

The user scripts' collection associated with the view.

This property was introduced in QtWebEngine 1.1.

See also WebEngineScriptCollection.

[since QtWebEngine 1.1] webChannel : QQmlWebChannel

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 property was introduced in QtWebEngine 1.1.

[since QtWebEngine 1.3] webChannelWorld : int

JavaScript world that the web channel instance used by this view is installed in. The world must be a number between `0` and `256`.

This property was introduced in QtWebEngine 1.3.

`[since QtWebEngine 2.0]` newWindowRequested(WebEngineNewWindowRequest request)

This signal is emitted when request is issued to load a page in a separate web engine view. 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.

The signal is handled by calling acceptAsNewWindow() on the destination view. If this signal is not 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.
                 onNewWindowRequested: function(request) {
                     var newWindow = windowComponent.createObject(windowParent);
                     newWindow.webView.acceptAsNewWindow(request);
                 }
             }
         }
     }

Note: The corresponding handler is `onNewWindowRequested`.

See also printToPdf.

`[since QtWebEngine 1.3]` recentlyAudibleChanged(bool recentlyAudible)

This signal is emitted when the page's audible state, specified by recentlyAudible, is changed, due to audio being played or stopped.

Note: The signal is also emitted when the audioMuted property changes. Also if the audio is paused, this signal is emitted with an approximate two-second delay, from the moment the audio is paused.

If a web page contains two videos that are started in sequence, this signal gets emitted only once, for the first video to generate sound. After both videos are stopped, the signal is emitted upon the last sound generated. This means that the signal is emitted both when any kind of sound is generated and when everything is completely silent within a web page, regardless of the number of audio streams.

Spurious signal emissions might also happen. For example, when sound is stopped, this signal gets emitted first with a value of `true`, and then with a value of `false`. Further, when audio starts playing, the signal is emitted twice with a value of `true`.

Note: The corresponding handler is `onRecentlyAudibleChanged`.

This signal was introduced in QtWebEngine 1.3.

See also recentlyAudible.

`[since QtWebEngine 1.7]` registerProtocolHandlerRequested(RegisterProtocolHandlerRequest request)

See also renderProcessPid.

`[since QtWebEngine 1.2]` renderProcessTerminated(RenderProcessTerminationStatus terminationStatus, int exitCode)

This signal is emitted when the render process is terminated with a non-zero exit status. terminationStatus is the termination status of the process and exitCode is the status code with which the process terminated.

Note: The corresponding handler is `onRenderProcessTerminated`.

This signal was introduced in QtWebEngine 1.2.

See also RenderProcessTerminationStatus.

`[since QtWebEngine 1.9]` selectClientCertificate(WebEngineClientCertificateSelection clientCertificateSelection)

This signal is emitted when a web site requests an SSL client certificate, and one or more were found in the system's client certificate store.

Handling the signal is asynchronous, and loading will be waiting until a certificate is selected, or the last copy of clientCertificateSelection is destroyed.

If the signal is not handled, clientCertificateSelection is automatically destroyed, and loading will continue without a client certificate.

Note: The corresponding handler is `onSelectClientCertificate`.

This signal was introduced in QtWebEngine 1.9.

See also WebEngineClientCertificateSelection.

`[since QtWebEngine 1.10]` tooltipRequested(TooltipRequest request)

This signal is emitted when the web page sends a request to show a tooltip at a specified position.
