+
+    QWebEngineClientHints allows configuration of exposing browser and platform information via

+
+    The information accessed via this API is split into two groups: low entropy and high entropy hints.
+    Low entropy hints (\l{QWebEngineClientHints::platform}{platform} and \l{QWebEngineClientHints::mobile}{mobile})
+    are those that do not give away much information; the API makes these accessible with every request and they can not
+    be disabled by QWebEngineClientHints::setAllClientHintsEnabled.
+
+    All the others are high entropy hints; they have the potential to give away more information, therefore they can be
+    disabled by QWebEngineClientHints::setAllClientHintsEnabled.
+
+    Each profile object has its own QWebEngineClientHints object, which configures the
+    Client Hint settings for that browsing context. If a Client Hint is not configured for a web engine
+    profile, its default value is deduced from the system.

+    \brief A request for populating a dialog with available sources for screen capturing.
+
+    \since 6.7
+
+    \inmodule QtWebEngineCore
+
+    To allow web applications to capture contents of a display, applications must connect
+    to QWebEnginePage::desktopMediaRequested, which takes a QWebEngineDesktopMediaRequest
+    instance as an argument.
+
+    If a web application requests access to the contents of a display,
+    QWebEnginePage::desktopMediaRequested will be emitted with a
+    QWebEngineDesktopMediaRequest instance as an argument which holds references to
+    QAbstractListModels for available windows and screens that can be captured.
+
+    The data model's \e Qt::DisplayRole specifies the name of the source which is the title of a
+    window or the number of the display.
+    The model is dynamically updates if the available list of sources has changed e.g a window is
+    opened/closed.
+
+    The signal handler needs to then either call QWebEngineDesktopMediaRequest:selectScreen() or
+    QWebEngineDesktopMediaRequest::selectWindow() to accept the request and start screensharing.

+
+    A web engine frame represents a single frame within a web page, such as those created by
+    \c <frame> or \c <iframe> HTML elements.
+    An active QWebEnginePage has one or more frames arranged in a tree structure. The top-level
+    frame, the root of this tree, can be accessed through the mainFrame() method, and
+    children() provides a frame's direct descendants.
+
+    A frame's lifetime is, at most, as long as the QWebEnginePage object that produced it.
+    However, frames may be created and deleted spontaneously and dynamically, for example through
+    navigation and script execution. Because of this, many QWebEngineFrame methods return
+    optional values, which will be \c std::nullopt if the frame no longer exists.

+    Runs the JavaScript code contained in \a script on this frame, without checking
+    whether the DOM of the page has been constructed.
+    To avoid conflicts with other scripts executed on the page, the world in
+    which the script is run is specified by \a worldId. The world ID values are
+    the same as provided by QWebEngineScript::ScriptWorldId, and between \c 0
+    and \c 256. If you leave out the \c world ID, the script is run in the
+    \c MainWorld.
+    When the script has been executed, \a callback is called with the result of the last
+    executed statement. \c callback can be any of a function pointer, a functor or a lambda,
+    and it is expected to take a QVariant parameter. For example:
+    \code
+    page.runJavaScript("document.title", [](const QVariant &v) { qDebug() << v.toString(); });
+    \endcode
+    Only plain data can be returned from JavaScript as the result value.
+    Supported data types include all of the JSON data types as well as, for
+    example, \c{Date} and \c{ArrayBuffer}. Unsupported data types include, for
+    example, \c{Function} and \c{Promise}.
+    \warning Do not execute lengthy routines in the callback function, because it might block the
+    rendering of the web engine page.
+    \warning We guarantee that the \a callback is always called, but it might be
+   done during page destruction. When QWebEnginePage is deleted, the callback is triggered with an
+   invalid value and it is not safe to use the corresponding QWebEnginePage or QWebEngineView

+/*!
+    \class QWebEnginePermission
+    \inmodule QtWebEngineCore
+    \since 6.8
+    \brief A QWebEnginePermission is an object used to access and modify the state of a single permission that's been
+    granted or denied to a specific origin URL.
+
+    The typical usage pattern is as follows:
+    \list 1
+        \li A website requests a specific feature, triggering the QWebEnginePage::permissionRequested() signal;
+        \li The signal handler triggers a prompt asking the user whether they want to grant the permission;
+        \li When the user has made their decision, the application calls \l grant() or \l deny();
+    \endlist
+
+    Alternatively, an application interested in modifying already granted permissions may use QWebEngineProfile::listPermissions()
+    to get a list of existing permissions associated with a profile, or QWebEngineProfile::getPermission() to get
+    a QWebEnginePermission object for a specific permission.
+
+    The \l origin() property can be used to query which origin the QWebEnginePermission is associated with, while the
+    \l feature() property describes the associated feature. A website origin is the combination of its scheme, hostname,
+    and port. Permissions are granted on a per-origin basis; thus, if the web page \c{https://www.example.com:12345/some/page.html}
+    requests a permission, it will be granted to the origin \c{https://www.example.com:12345/}.
+
+    \l QWebEnginePermission::Feature describes all the feature types Qt WebEngine supports. Some Features are transient;
+    in practice, this means that they are never remembered, and a website that uses them will trigger a permission
+    prompt every time the Feature is needed. Transient Features cannot be granted in advance.
+
+    The usability lifetime of a QWebEnginePermission is tied either to its associated QWebEnginePage
+    (for transient feature types), or QWebEngineProfile (for permanent feature types). A transient permission is one which
+    needs to be explicitly granted or denied every time it's needed (e.g. webcam/screen sharing permission), whereas a permanent
+    one might be stored inside the current profile, depending on the value of QWebEngineProfile::persistentPermissionsPolicy().
+    You can check whether a QWebEnginePermission is in a valid state using its \l isValid() property. For invalid objects, calls to \l grant(),
+    \l deny(), or \l reset() will do nothing, while calls to \l state() will always return QWebEnginePermission::Invalid.

+    This enum describes the policy for permission persistence:
+
+    \value  NoPersistentPermissions
+            The application will ask for permissions every time they're needed, regardless of
+            whether they've been granted before or not. This is intended for backwards compatibility
+            with existing applications, and otherwise not recommended.
+    \value  PersistentPermissionsInMemory
+            A request will be made only the first time a permission is needed. Any subsequent
+            requests will be automatically granted or denied, depending on the initial user choice.
+            This carries over to all pages that use the same QWebEngineProfile instance, until the
+            application is shut down. This is the setting applied if \c off-the-record is set
+            or no persistent data path is available.
+    \value  PersistentPermissionsOnDisk
+            Works the same way as \c PersistentPermissionsInMemory, but the permissions are saved to

+    into the web engine, they have the advantage in terms of efficiency and security:
+    There is no need for generating and parsing HTTP messages or for transferring data
+    over sockets, nor any way to intercept or monitor the traffic.
+
     To implement a custom URL scheme for QtWebEngine, you first have to create an instance of
     QWebEngineUrlScheme and register it using QWebEngineUrlScheme::registerScheme().
 
+    As custom schemes are integrated directly into the web engine, they do not
+    necessarily need to follow the standard security rules which apply to
+    ordinary web content. Depending on the chosen configuration, content served
+    over a custom scheme may be given access to local resources, be set to
+    ignore Content-Security-Policy rules, or conversely, be denied access to any
+    other content entirely. If it is to be accessed by normal content, ensure cross-origin
+    access is enabled, and if accessed from HTTPS that it is marked as secure.
+
     \note Make sure that you create and register the scheme object \e before the QGuiApplication
     or QApplication object is instantiated.

+    \brief The QWebEngineWebAuthUxRequest class encapsulates the data of a WebAuth UX request.
+    \since 6.7
+
+    \inmodule QtWebEngineCore
+
+    This class contains the information and API for WebAuth UX. WebAuth may require user
+    interaction during the authentication process. These requests are handled by displaying a
+    dialog to users. QtWebEngine currently supports user verification, resident credentials,
+    and display request failure UX requests.
+
+    QWebEngineWebAuthUxRequest models a WebAuth UX request throughout its life cycle,
+    starting with showing a UX dialog, updating it's content through state changes, and
+    finally closing the dialog.
+
+    WebAuth UX requests are normally triggered when the authenticator requires user interaction.
+    It is the QWebEnginePage's responsibility to notify the application of the new WebAuth UX
+    requests, which it does by emitting the
+    \l{QWebEnginePage::webAuthUxRequested}{webAuthUxRequested} signal together with a newly
+    created QWebEngineWebAuthUxRequest. The application can then examine this request and
+    display a WebAuth UX dialog.
+
+    The QWebEngineWebAuthUxRequest object periodically emits the \l
+    {QWebEngineWebAuthUxRequest::}{stateChanged} signal to notify potential
+    observers of the current WebAuth UX states. The observers update the WebAuth dialog
+    accordingly.
+
+    For more information about how to handle web engine authenticator requests, see the

+    \title Changes to Qt WebEngine
+    \ingroup changes-qt-5-to-6
+    \brief Migrate Qt WebEngine to Qt 6.
+
+    Qt 6 is a result of the conscious effort to make the framework more
+    efficient and easy to use.
+
+    We try to maintain binary and source compatibility for all the public
+    APIs in each release. But some changes were inevitable in an effort to
+    make Qt a better framework
+
+    In this topic we summarize those changes in Qt WebEngine, and provide guidance
+    to handle them.
+
+    \section1 Moved Classes
+
+    \section2 The Qt WebEngine module
+    Has been renamed to the Qt WebEngineQuick module to not collide with the name of
+    the super module, and to be consistent with other Quick modules.
+
+    If you port your Qt Quick application, please remember to use the new module
+    name in your qmake project file.
+
+    \code
+        QT += webenginequick
+    \endcode
+
+    \section2 Classes moved from Qt WebEngineWidgets to Qt WebEngineCore
+    Several classes have been moved from Qt WebEngineWidgets to Qt WebEngineCore if they
+    did not use the Widgets module. In most cases this change should be source compatible unless
+    you included the module name in the include header, in which case you need to update your
+    includes.
+
+    \section3 Classes moved with minimal changes
+    \list
+    \li QWebEngineHistory
+    \li QWebEngineProfile
+    \li QWebEngineScript
+    \li QWebEngineScriptCollection
+    \li QWebEngineClientCertificateSelection
+    \li QWebEngineSettings
+    \li QWebEngineFullScreenRequest
+    \endlist
+
+    \section3 QWebEngineCertificateError
+    Has been unified between QML and C++ versions, so both are now accepted or rejected via methods
+    on the class.
+
+    \section3 QWebEngineContextMenuData
+    Has been moved to Core and renamed QWebEngineContextMenuRequest.
+
+    \section3 QWebEngineDownloadItem
+    Has been moved to Core and renamed QWebEngineDownloadRequest.
+
+    \section3 QWebEnginePage
+    Has been moved to Core, and API that worked on QWebEngineView or QPrinter has been moved, and can now
+    be accessed only from QWebEngineView. See Changed API.
+
+    \section2 Classes moved from Qt WebEngineQuick to Qt WebEngineCore
+
+    \section3 WebEngineNavigationRequest
+    Is now QWebEngineNavigationRequest, and accessible from C++ API as well, adding a more
+    informative variant of QWebEnginePage::acceptNavigationRequest().
+
+    \section3 WebEngineNewViewRequest
+    Is now WebEngineNewWindowRequest and QWebEngineNewWindowRequest, and accessible from C++ API as well,
+    adding a more informative variant of QWebEnginePage::createWindow().
+
+
+    \section1 Changed API
+
+    \section2 C++
+
+    \section3 QWebEnginePage::certificateError()
+    Is now a signal instead of a derived method. The errors are either accepted or rejected
+    via methods on the QWebEngineCertificateError class.
+
+    \section3 QWebEnginePage::print()
+    Has been moved to QWebEngineView::print() and no longer takes a callback argument but
+    signals finished with QWebEngineView::printFinished() instead. It was never possible
+    to have two active print jobs at the same time.
+
+    \section3 QWebEnginePage::view()
+    Has been removed as QWebEnginePage and QWebEngineView are now in different modules. The view
+    associated with a page can be accessed using the static helper QWebEngineView::forPage().
+
+    \section3 QWebEngineProfile::defaultProfile()
+    Has been removed. The default profile is now an off-the-record profile, and only used if a
+    QWebEnginePage is created without an explicit profile. To maintain Qt 5 like behavior, create
+    a global profile called "Default" and use it when creating every QWebEnginePage.
+
+    \section2 QML
+
+    \section3 WebEngineNavigationRequest
+    The navigation requests are now accepted or rejected like other request objects using accept()
+    or reject() methods.
+
+    \section3 WebEngineNewViewRequest
+    Has been renamed WebEngineNewWindowRequest.
+
+    \section1 Changed Behavior
+
+    \section2 Default Profile
+    The default profile is now \e{off the record}. To have a standard browser profile with
+    disk-cache and cookies, we recommend creating your own profile and using that explicitly.
+
+    \section2 QRC Scheme
+    Can no longer be accessed from custom schemes by default, nor can it access local content
+    directly. If the Qt 5 behavior is needed, it can be restored by registering the qrc scheme
+    like a custom URL scheme, and setting the CorsEnabled and LocalAccessAllowed access flags.
+    \code
+        QWebEngineUrlScheme qrcScheme(QByteArrayLiteral("qrc"));
+        qrcScheme.setFlags(QWebEngineUrlScheme::SecureScheme
+                           | QWebEngineUrlScheme::LocalAccessAllowed
+                           | QWebEngineUrlScheme::CorsEnabled
+                           | QWebEngineUrlScheme::ViewSourceAllowed);
+        QWebEngineUrlScheme::registerScheme(qrcScheme);
+    \endcode
+
+    \section2 OCSP Certificate Revocation Checking
+    In Qt 5 OCSP could be enabled on Linux using QWebEngineProfile::setUseForGlobalCertificateVerification(true)
+    on a QWebEngineProfile. This has been removed in Qt6 as this specific form of OCSP is considered bad. As
+    of Qt 6.2, no new method for revoked certificate checking on Linux has yet been added.

+\section1 Description
+
+    A spell checker in Qt Web Engine needs dictionaries in a specific binary format.
+    This CMake command converts dictionaries from the \l{Hunspell project}. into the \c bdict
+    binary format. It creates a \c qtwebengine_dictionaries target, which your project can
+    use as a dependency. This way your project can easily add dictionaries for the spell
+    checker. Refer to the \l{WebEngine Widgets Spellchecker Example}{spell checker example}
+    for more details.
+
+\section1 Arguments
+
+    \c TARGET is an optinal argument and specifies the name of the application target that should
+    depend on \c qtwebengine_dictionaries target. In other words it is used to define a build
+    dependency to create the binary format of dictionaries before building \c TARGET.
+
+    \c SOURCE is the absolute path to the \l{Hunspell project} dictionary for which
+    a corresponding binary format (\c.bdict) will be created.
+
+    \c OUTPUT_DIRECTORY is an optional argument and specifies the directory where the binary format
+    of the dictionary will be created. If not specified, \c CMAKE_CURRENT_BINARY_DIR will be used
+    as \c OUTPUT_DIRECTORY.
+
+    \note The \c qtwebengine_dictionaries directory or \c <CONFIG>/qtwebengine_dictionaries
+    directories in the case of the multi-config generator is appended to OUTPUT_DIRECTORY. This
+    helps to utilize dictionaries, as the \c webengine_dictionaries directory is the default
+    search location.

+
+    To deploy a \QWE application on \macos, you will need to ensure that the \QWE process is signed
+    with an entitlements file that at least contains the entitlements listed in
+    QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/Resources/QtWebEngineProcess.entitlements.
+
+    To deploy a \QWE application that accesses the microphone or camera
+    on \macos, you will need to provide texts for the messages that will be shown to the user to
+    explain why the application asks for permission to access to the camera or microphone.
+    To do this, add the texts to the application's \c Info.plist file using the keys
+    described below.
+
+    For the camera usage message, provide a text using the following key:
+    \code
+    <key>NSCameraUsageDescription</key>
+    <string>Your message text for camera usage.</string>
+    \endcode
+
+    See also \l{https://developer.apple.com/documentation/bundleresources/information_property_list/nscamerausagedescription}
+    {Apple's property list file documentation}.
+
+    For the microphone usage message, provide a text using the following key:
+    \code
+    <key>NSMicrophoneUsageDescription</key>
+    <string>Your message text for microphone usage.</string>
+    \endcode
+
+    See also \l{https://developer.apple.com/documentation/bundleresources/information_property_list/nsmicrophoneusagedescription}
+    {Apple's property list file documentation}.
+
+    To notarize an application that accesses the camera or the microphone,
+    you will need to add the corresponding keys to your application's entitlements file used for
+    deployment and notarization.
+
+    To enable access to the camera, add:
+    \code
+    <key>com.apple.security.device.camera</key>
+    <true/>
+    \endcode
+
+    See also \l{https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_device_camera}

+    \section1 WebEngineDriver
+
+    With WebEngineDriver, you can automate the testing of web sites across browsers.
+    WebEngineDriver is based on ChromeDriver and can be used the same way.
+    For more information about ChromeDriver and its use, visit
+    \l {https://chromedriver.chromium.org/}{ChromeDriver user site}.
+
+    WebEngineDriver has slight modifications compared to ChromeDriver to be able to connect to
+    \QWE based browsers. It is compatible with \QWE example browsers, such as
+    \l {WebEngine Widgets Simple Browser Example}{Simple Browser} or
+    \l{WebEngine Quick Nano Browser}{Nano Browser}.
+
+    The browser automation is scripted through a WebDriver client like the
+    \l {https://www.selenium.dev/}{Selenium WebDriver}.
+    For example, WebEngineDriver can be used with the Python lanugage bindings of
+    Selenium WebDriver:
+
+    \code
+    from selenium import webdriver
+    from selenium.webdriver.chrome.service import Service
+
+    service = Service(executable_path='QTDIR/libexec/webenginedriver')
+    options = webdriver.ChromeOptions()
+    options.binary_location = 'path/to/browser_binary'
+
+    driver = webdriver.Chrome(service=service, options=options)
+    driver.get("http://www.google.com/")
+    driver.quit()
+    \endcode
+
+    In this example,
+    \list
+    \li \c executable_path has to be set to the WebEngineDriver's binary path
+    \li \c QTDIR is the directory where Qt is installed
+    \li \c options.binary_location has to be set to the browser's binary path
+    \endlist
+
+    \note On Windows: \c executable_path='QTDIR/bin/webenginedriver.exe'
+
+    Before executing the script, the \c QTWEBENGINE_REMOTE_DEBUGGING environment variable has to
+    be set. Its value is a port number what is used by both the browser and WebEngineDriver to
+    communicate with each other.
+    \badcode
+    export QTWEBENGINE_REMOTE_DEBUGGING=12345
+    \endcode
+
+    By executing, the script opens the specified web browser and loads the Google web site.
+
+    WebEngineDriver can be also attached to an already running browser if it was started with the
+    remote debugging port set. \c options.debugger_address has to be set to the remote debugging
+    address in the script:
+
+    \code
+    options.debugger_address = 'localhost:12345'
+    \endcode
+
+    In this case, \c options.binary_location should not be set because the browser is already
+    running. The environment variable \c QTWEBENGINE_REMOTE_DEBUGGING is not used by the
+    WebEngineDriver if \c options.debugger_address is set.
+
+    \note WebEngineDriver must be built with the same version of Chromium as \QWE is using.

+    \section1 Favicon
+
+    \QWE supports the web site URL icon, \e favicon. Each icon is stored in the internal
+    database for each \l QWebEngineProfile and can be accessed using a \l QWebEnginePage::icon()
+    call or a \l {WebEngineView::icon}{WebEngineView.icon} property for the currently loaded content.
+
+    Moreover \QWE provides API for accessing already stored icons in the internal profile's database.
+
+    \note The icon database is not available for off-the-record profiles.
+
+    \section2 QML Favicon Handling
+
+    For accessing icons a \c QQuickImageProvider is registered. This provider can be
+    accessed by a special URL where the scheme is "image:" and the host is "favicon".
+
+    \qml
+    Image {
+        source: "image://favicon/url"
+    }
+    \endqml
+
+    The \c url can be the URL of the favicon:
+
+    \qml
+    Image {
+        source: "image://favicon/https://www.qt.io/hubfs/2016_Qt_Logo/qt_logo_green_rgb_16x16.png"
+    }
+    \endqml
+
+    The \c url also can be a page URL to access its icon:
+
+    \qml
+    Image {
+        source: "image://favicon/https://www.qt.io/"
+    }
+    \endqml
+
+    If more than one icon is available, the \l {Image::sourceSize} property can be
+    specified to choose the icon with the desired size. If \l {Image::sourceSize}
+    is not specified or 0, the largest available icon will be chosen.
+
+    The image provider looks up the requested icon in the existing \l {WebEngineView}
+    instances. First, it tries to match the currently displayed icons. If no match
+    has been found it requests the icon from the database. Each profile has its
+    own icon database and it is stored in the persistent storage thus the stored icons
+    can be accessed without network connection too. The icon must be previously loaded
+    to be stored in the database.
+

+    \section1 Hardware Acceleration
+
+    QtWebEngine tries to use hardware acceleration for rendering the content. It uses
+    \c OpenGL or \c OpenGLES APIs to execute rendering calls on the GPU. As a fallback,
+    software rendering is used whenever the hardware does not meet the required set of
+    OpenGL functionality. A user can check the current hardware acceleration state by
+    loading the \c {chrome://gpu} internal page. Moreover, the acceleration can be explicitly

+    \section1 Page Lifecycle API
+
+    \QWE supports the \l {https://wicg.github.io/page-lifecycle/spec.html}{Page
+    Lifecycle API specification}, a work-in-progress extension to the HTML
+    standard for allowing user agents to reduce their resource consumption by
+    freezing or discarding background pages. The feature is exposed both in the
+    Widgets and QML APIs.
+
+    For an example of the QML API in use, see the \l {WebEngine Lifecycle
+    Example}.
+
+    Support for this feature was added in Qt 5.14.0.
+
+    \section2 Overview of Lifecycle States
+
+    Each \l {WebEngineView} item (or \l {QWebEnginePage} object) can be in one
+    of three \e {lifecycle states}: active, frozen, or discarded. These states,
+    like the sleep states of a CPU, control the resource usage of web views.
+
+    The \e {active} state is the normal, unrestricted state of a web view. All
+    visible web views are always in the active state, as are all web views that
+    have not yet finished loading. Only invisible, idle web views can be
+    transitioned to other lifecycle states.
+
+    The \e {frozen} state is a low CPU usage state. In this state, most HTML
+    task sources are suspended (frozen) and, as a result, most DOM event
+    processing and JavaScript execution will also be suspended. The web view
+    must be invisible in order to be frozen as rendering is not possible in this
+    state.
+
+    The \e {discarded} state is an extreme resource-saving state. In this state,
+    the browsing context of the web view will be discarded and the corresponding
+    renderer subprocess shut down. CPU and memory usage in this state is reduced
+    virtually to zero. On exiting this state the web page will be automatically
+    reloaded. The process of entering and exiting the discarded state is similar
+    to serializing the browsing history of the web view and destroying the view,
+    then creating a new view and restoring its history.
+
+    See also \l {WebEngineView::LifecycleState}. The equivalent in the Widgets
+    API is \l {QWebEnginePage::LifecycleState}.
+
+    \section2 The \c {lifecycleState} and \c {recommendedState} Properties
+
+    The \l {WebEngineView::}{lifecycleState} property of the \l {WebEngineView}
+    type is a read-write property that controls the current lifecycle state of
+    the web view. This property is designed to place as few restrictions as
+    possible on what states can be transitioned to. For example, it is allowed
+    to freeze a web view that is currently playing music in the background,
+    stopping the music. In order to implement a less aggressive resource-saving
+    strategy that avoids interrupting user-visible background activity, the \l
+    {WebEngineView::} {recommendedState} property must be used.
+
+    The \l {WebEngineView::}{recommendedState} property of the \l
+    {WebEngineView} type is a read-only property that calculates a safe limit on
+    the \l {WebEngineView::}{lifecycleState} property, taking into account the
+    current activity of the web view. So, in the example of a web view playing
+    music in the background, the recommended state will be \c {Active} since a
+    more aggressive state would stop the music. If the application wants to
+    avoid interrupting background activity, then it should avoid putting the web
+    view into a more aggressively resource-saving lifecycle state than what's
+    given by \l {WebEngineView::}{recommendedState}.
+
+    See also \l {WebEngineView::lifecycleState} and \l
+    {WebEngineView::recommendedState}. The equivalents in the Widgets API are \l
+    {QWebEnginePage::lifecycleState} and \l {QWebEnginePage::recommendedState}.
+
+    \section2 The DOM Extensions
+
+    The \l {WebEngineView::}{lifecycleState} property is connected to the \l
+    {https://wicg.github.io/page-lifecycle/spec.html}{Page Lifecycle API
+    specification}, which specifies two new DOM events, \c {freeze} and \c
+    {resume}, and adds a new \c {Document.wasDiscarded} boolean property. The \c
+    {freeze} and \c {resume} events are fired when transitioning from the \c
+    {Active} to the \c {Frozen state}, and vice-versa. The \c
+    {Document.wasDiscarded} property is set to \c {true} when transitioning from
+    the \c {Discarded} state to the \c {Active} state.

     \section1 Sandboxing Support
 
-    \QWE provides out-of-the-box sandboxing support for Chromium render processes on Linux
-    and \macos. Sandboxing is currently not supported on Windows due to a limitation in how
-    the sandbox is set up and how it interacts with the host process provided by the \QWE

+    \QWE provides out-of-the-box sandboxing support for Chromium render
+    processes.
+
+    On Linux, note the following restrictions:
+
+    \list
+        \li The kernel has to support the anonymous namespaces feature
+            (kernel version 3.8 or later). However, on Debian, Ubuntu,
+            and other Debian-derived distributions, this feature is off
+            by default. It can be turned on by setting
+            \c /proc/sys/kernel/unprivileged_userns_clone to 1.
+        \li The kernel has to support the \c seccomp-bpf feature (kernel
+            version 3.5 or later).
+        \li Setuid sandboxes are not supported and are thus disabled.
+    \endlist
 
-    On \macos, there are no special requirements for enabling sandbox support.
+    To explicitly disable sandboxing, use one of the following options:
 
-    On Linux, the kernel has to support the anonymous namespaces feature (kernel version >= 3.8)
-    and seccomp-bpf feature (kernel version >= 3.5). Setuid sandboxes are not supported and are thus
-    disabled.

+        \li Set the \c QTWEBENGINE_DISABLE_SANDBOX environment variable to 1.
+        \li Pass the \c{--no-sandbox} command line argument to the user
+            application executable.
+        \li Set \c QTWEBENGINE_CHROMIUM_FLAGS to \c{--no-sandbox}.
+    \endlist
 
-    To explicitly disable sandboxing, the \c QTWEBENGINE_DISABLE_SANDBOX environment variable can be

+
+The \QWE module uses Chromium to provide most of its
+functionality. During the build process, Chromium becomes
+a part of the \l{Qt WebEngine Core} library.
+Therefore, when distributing \QWE, users need to comply
+to both the licenses of the \QWE part as developed under
+the Qt Project, as well as the licenses that are part of
+Chromium.
+
+The Qt specific parts of the \QWE module are available under
+commercial licenses from The Qt Company. Alternatively,
+they are available under GNU Lesser General Public License v3.0,
+or GNU General Public License v3.0, or
+GNU General Public License v2.0.
+
+The Chromium part contains code available under various
+licenses, with the most restrictive license being the
+\e{GNU Lesser General Public License v2.1} (LGPL 2.1).
+For a full list, see \l{Third-Party Licenses} below.

+\section1 Complying with LGPL 2.1
+
+The Qt Company allows commercial customers to
+distribute the source code of the \QWE module alongside the
+\QWE binaries, and allows recipients to customize and build
+\QWE from sources. This includes building and using
+such a modified \QWE with an application or system using
+an otherwise commercially licensed Qt.

+as part of a commercial-only Long-Term Support release (LTS, see

+Third party licenses included in the sources as part of Chromium

+    \page qtpdf-index.html
+    \title Qt PDF
+
+    \brief Renders pages from PDF documents.
+
+    The Qt PDF module contains classes and functions for rendering
+    PDF documents. The \l QPdfDocument class loads a PDF document
+    and renders pages from it according to the options provided by
+    the \l QPdfDocumentRenderOptions class. The \l QPdfPageRenderer
+    class manages a queue that collects all render requests. The
+    \l QPdfPageNavigator class handles the navigation through a
+    PDF document. The \l QPdfSearchModel class searches for a string
+    and holds the search results. The QPdfBookmarkModel class holds the
+    table of contents, if present. The QPdfLinkModel holds information
+    about hyperlinks on a page. The \l QPdfView widget is a complete
+    PDF viewer, and the \l {PDF Viewer Widget Example} shows how to use it.
+
+    For Qt Quick applications, three kinds of full-featured viewer
+    components are provided. \l PdfMultiPageView should be your
+    first choice for the most common user experience: flicking
+    through the pages in the entire document.
+    \l PdfScrollablePageView shows one page at a time, with scrolling;
+    and \l PdfPageView shows one full page at a time, without scrolling.
+
+    The full-featured viewer components are composed of lower-level
+    QML components that can be used separately if you need to write a
+    more customized PDF viewing application: \l PdfDocument,
+    \l PdfPageImage, \l PdfPageNavigator, \l PdfSelection,
+    \l PdfSearchModel, \l PdfLinkModel, and \l PdfBookmarkModel.
+
+    If you only need to render page images, without features such as
+    text selection, search and navigation, this module includes a
+    \l QImageIOHandler plugin that treats PDF as a scalable
+    \l {Qt Image Formats}{image format}, similar to \l {Qt SVG}{SVG}.
+    You can simply use \l Image, and set the
+    \l {Image::currentFrame}{currentFrame} property to the page index
+    that you wish to display. If the PDF file does not render its own
+    background, the image has a transparent background.
+
+    \include module-use.qdocinc using qt module

+    \inqmlmodule QtQuick.Pdf
+    \brief A complete PDF viewer component for scrolling through multiple pages.
+
+    PdfMultiPageView provides a PDF viewer component that offers a user
+    experience similar to many common PDF viewer applications. It supports
+    flicking through the pages in the entire document, with narrow gaps between
+    the page images.
+
+    PdfMultiPageView also supports selecting text and copying it to the
+    clipboard, zooming in and out, clicking an internal link to jump to another
+    section in the document, rotating the view, and searching for text. The
+    \l {PDF Multipage Viewer Example} demonstrates how to use these features
+    in an application.
+
+    The implementation is a QML assembly of smaller building blocks that are
+    available separately. In case you want to make changes in your own version
+    of this component, you can copy the QML, which is installed into the
+    \c QtQuick/Pdf/qml module directory, and modify it as needed.

+    \qmltype PdfPageView
+    \inqmlmodule QtQuick.Pdf
+    \brief A PDF viewer component to show one page a time.
+
+    PdfPageView provides a PDF viewer component that shows one whole page at a
+    time, without scrolling. It supports selecting text and copying it to the
+    clipboard, zooming in and out, clicking an internal link to jump to another
+    section in the document, rotating the view, and searching for text.
+
+    The implementation is a QML assembly of smaller building blocks that are
+    available separately. In case you want to make changes in your own version
+    of this component, you can copy the QML, which is installed into the
+    \c QtQuick/Pdf/qml module directory, and modify it as needed.

+    \qmltype PdfScrollablePageView
+    \inqmlmodule QtQuick.Pdf
+    \brief A complete PDF viewer component to show one page a time, with scrolling.
+
+    PdfScrollablePageView provides a PDF viewer component that shows one page
+    at a time, with scrollbars to move around the page. It also supports
+    selecting text and copying it to the clipboard, zooming in and out,
+    clicking an internal link to jump to another section in the document,
+    rotating the view, and searching for text. The pdfviewer example
+    demonstrates how to use these features in an application.
+
+    The implementation is a QML assembly of smaller building blocks that are
+    available separately. In case you want to make changes in your own version
+    of this component, you can copy the QML, which is installed into the
+    \c QtQuick/Pdf/qml module directory, and modify it as needed.

+    \value zoom
+        If the link is an internal link, the intended zoom level on the destination page.

+    \since 5.15
+
+    PdfSelection provides the text string and its geometry within a bounding box
+    from one point to another.
+
+    To modify the selection using the mouse, bind \l from and \l to
+    to the suitable properties of an input handler so that they will be set to
+    the positions where the drag gesture begins and ends, respectively; and
+    bind the \l hold property so that it will be set to \c true during the drag
+    gesture and \c false when the gesture ends.
+
+    PdfSelection also directly handles Input Method queries so that text
+    selection handles can be used on platforms such as iOS. For this purpose,
+    it must have keyboard focus.

-
-    This QML type contains information about a certificate error that occurred. The \l error
-    property holds the reason that the error occurred and the \l description property holds a
-    short localized description of the error. The \l url property holds the URL that triggered
-    the error.
-
-    The certificate can be rejected by calling \l rejectCertificate, which will stop loading the
-    web engine request. By default, an invalid certificate will be automatically rejected.
-
-    The certificate error can be ignored by calling \l ignoreCertificateError, which will
-    resume loading the request.
-
-    It is possible to defer the decision of rejecting a certificate by calling \l defer,
-    which is useful when waiting for user input.

-    \instantiates QQuickWebEngineContextMenuRequest
-    \inqmlmodule QtWebEngine
-    \since QtWebEngine 1.4
-
-    \brief A request for showing a context menu.
-
-    A ContextMenuRequest is passed as an argument of the
-    WebEngineView::contextMenuRequested signal. It provides further
-    information about the context of the request. The position of the
-    request origin can be found via the \l x and \l y properties.
-
-    The \l accepted property of the request indicates whether the request
-    is handled by the user code or the default context menu should
-    be displayed.
-
-    The following code uses a custom menu to handle the request:
-
-    \code
-    WebEngineView {
-        id: view
-        // ...
-        onContextMenuRequested: function(request) {
-            request.accepted = true;
-            myMenu.x = request.x;
-            myMenu.y = request.y;
-            myMenu.trigger.connect(view.triggerWebAction);
-            myMenu.popup();
-        }
-        // ...

-    \brief Provides information about a download.
-
-    WebEngineDownloadItem models a download throughout its life cycle, starting
-    with a pending download request and finishing with a completed download. It
-    can be used, for example, to get information about new downloads, to monitor
-    progress, and to pause, resume, and cancel downloads.
-
-    Downloads are usually triggered by user interaction on a web page. It is the
-    WebEngineProfile's responsibility to notify the application of new download
-    requests, which it does by emitting the
-    \l{WebEngineProfile::downloadRequested}{downloadRequested} signal together
-    with a newly created WebEngineDownloadItem. The application can then examine
-    this item and decide whether to accept it or not. A signal handler must
-    explicitly call accept() on the item for \QWE to actually start
-    downloading and writing data to disk. If no signal handler calls accept(),
-    then the download request will be automatically rejected and nothing will be
-    written to disk.
-
-    \note Some properties, like the \l path under which the file will be saved,
-    can only be changed before calling accept().
-
-    \section2 Object Life Cycle
-
-    All items are guaranteed to be valid during the emission of the
-    \l{WebEngineProfile::downloadRequested}{downloadRequested} signal. If
-    accept() is \e not called by any signal handler, then the item will be
-    deleted \e immediately after signal emission. This means that the
-    application \b{must not} keep references to rejected download items.
-
-    \section2 Web Page Downloads
-
-    In addition to normal file downloads, which consist simply of retrieving
-    some raw bytes from the network and writing them to disk, \QWE also
-    supports saving complete web pages, which involves parsing the page's HTML,
-    downloading any dependent resources, and potentially packaging everything
-    into a special file format (\l savePageFormat). To check if a download is
-    for a file or a web page, use \l isSavePageDownload.

-    \inqmlmodule QtWebEngine
-    \since QtWebEngine 1.1
-
-    \brief Provides data models that represent the history of a web engine page.
-
-    The WebEngineHistory type can be accessed by using the
-    \l{WebEngineView::navigationHistory}{WebEngineView.navigationHistory} property.
-
-    The WebEngineHistory type provides the following WebEngineHistoryListModel data model objects:
-
-    \list
-        \li \c backItems, which contains the URLs of visited pages.
-        \li \c forwardItems, which contains the URLs of the pages that were visited after visiting
-            the current page.
-        \li \c items, which contains the URLs of the back and forward items, as well as the URL of
-            the current page.
-    \endlist
-
-    The easiest way to use these models is to use them in a ListView as illustrated by the
-    following code snippet:
-
-    \code
-    ListView {
-        id: historyItemsList
-        anchors.fill: parent
-        model: webEngineView.navigationHistory.items
-        delegate:
-            Text {
-                color: "black"
-                text: model.title + " - " + model.url + " (" + model.offset + ")"
-            }
-    }
-    \endcode
-
-    The ListView shows the content of the corresponding model. The delegate is responsible for the
-    format of the list items. The appearance of each item of the list in the delegate can be defined
-    separately (it is not web engine specific).
-
-    The model roles \e title, \e url, and \e icon specify the title, URL, and favicon of the
-    visited page. The \e offset
-    role specifies the position of the page in respect to the current page (0). A positive number
-    indicates that the page was visited after the current page, whereas a negative number indicates
-    that the page was visited before the current page.
-
-    The data models can also be used to create a menu, as illustrated by the following code
-    snippet:
-
-    \quotefromfile webengine/quicknanobrowser/BrowserWindow.qml
-    \skipto ToolBar
-    \printuntil onObjectRemoved
-    \printuntil }
-    \printuntil }
-    \printuntil }
-
-    For the complete example, see \l{WebEngine Quick Nano Browser}.

-    web content.
-

-
-    The point in the loading process at which the script will be executed.

-           The script will be executed as soon as the document is created. This is not suitable for
-           any DOM operation.
-    \value DocumentReady
-           The script will run as soon as the DOM is ready. This is equivalent to the
-           \c DOMContentLoaded event firing in JavaScript.
-    \value Deferred
-           The script will run when the page load finishes, or 500 ms after the document is ready,
-           whichever comes first.

-
-/*!
-    \enum QQuickWebEngineScript::ScriptWorldId
-

-
-    \value MainWorld
-           The world used by the page's web contents. It can be useful in order to expose custom
-           functionality to web contents in certain scenarios.
-    \value ApplicationWorld
-           The default isolated world used for application level functionality implemented in
-           JavaScript.
-    \value UserWorld
-           The first isolated world to be used by scripts set by users if the application is not
-           making use of more worlds. As a rule of thumb, if that functionality is exposed to the
-           application users, each individual script should probably get its own isolated world.

+
+    \since 6.8
+
+    This enum describes the policy for permission persistence:
+
+    \value  NoPersistentPermissions
+            The application will ask for permissions every time they're needed, regardless of
+            whether they've been granted before or not. This is intended for backwards compatibility
+            with existing applications, and otherwise not recommended.
+    \value  PersistentPermissionsInMemory
+            A request will be made only the first time a permission is needed. Any subsequent
+            requests will be automatically granted or denied, depending on the initial user choice.
+            This carries over to all pages that use the same QQuickWebEngineProfile instance, until the
+            application is shut down. This is the setting applied if \c off-the-record is set
+            or no persistent data path is available.
+    \value  PersistentPermissionsOnDisk
+            Works the same way as \c PersistentPermissionsInMemory, but the permissions are saved to

+    \brief Manages a collection of user scripts.
+    \since QtWebEngine 6.2
+
+    \inqmlmodule QtWebEngine
+
+    WebEngineScriptCollection handles a user scripts collection, which
+    is injected in the JavaScript engine during the loading of web content.
+
+    Use \l{WebEngineView::userScripts}{WebEgineView.userScripts} and
+    \l{WebEngineProfile::userScripts}{WebEngineProfile.userScripts} to access
+    the collection of scripts  associated with a single page or number of pages
+    sharing the same profile.
+
+    The collection of user script objects in QML can be created for a set of
+    user script objects by simple assignment to
+    \l{WebEngineScriptCollection::collection}{WebEngineScriptCollection.collection}
+    property or by WebEngineScriptCollection methods.
+
+    \note The new user script can be instantiated with JavaScript dictionaries when using
+    \e collection property.
+
+    See the following code snippets demonstrating the usage:
+
+    \list
+        \li \e collection property with JavaScript dictionaries
+        \code
+            var scriptFoo = { name: "Foo",

+                            injectionPoint: WebEngineScript.DocumentReady }
+
+            webEngineView.userScripts.collection = [ scriptFoo, scriptBar ];
+        \endcode
+        \li \e collection property with user script object as value type
+         \code
+            var script = WebEngine.script()
+            script.name = "FOO"
+            webEngineView.userScripts.collection = [ script ]
+         \endcode
+         \li user script collection \e insert method can be used only with value type
+            or list of value types
+         \code

+    \brief A request for showing a context menu.
+
+    A ContextMenuRequest is passed as an argument of the
+    WebEngineView::contextMenuRequested signal. It provides further
+    information about the context of the request. The \l position
+    property provides the origin of the request.

+    The \l accepted property of the request indicates whether the request
+    is handled by the user code or the default context menu should
+    be displayed.
+
+    The following code uses a custom menu to handle the request:
+
+    \code
+    WebEngineView {
+        id: view
+        // ...
+        onContextMenuRequested: function(request) {

+
+    \brief Provides data models that represent the history of a web engine page.
+
+    The WebEngineHistory type can be accessed by using the
+    \l{WebEngineView::history}{WebEngineView.history} property.
+
+    The WebEngineHistory type provides the following WebEngineHistoryModel data model objects:
+
+    \list
+        \li \c backItems, which contains the URLs of visited pages.
+        \li \c forwardItems, which contains the URLs of the pages that were visited after visiting
+            the current page.
+        \li \c items, which contains the URLs of the back and forward items, as well as the URL of
+            the current page.
+    \endlist
+
+    The easiest way to use these models is to use them in a ListView as illustrated by the
+    following code snippet:
+
+    \code
+    ListView {
+        id: historyItemsList
+        anchors.fill: parent
+        model: webEngineView.history.items
+        delegate:
+            Text {
+                color: "black"
+                text: model.title + " - " + model.url + " (" + model.offset + ")"
+            }
+    }
+    \endcode
+
+    The ListView shows the content of the corresponding model. The delegate is responsible for the
+    format of the list items. The appearance of each item of the list in the delegate can be defined
+    separately (it is not web engine specific).
+
+    The model roles \e title, \e url, and \e icon specify the title, URL, and favicon of the
+    visited page. The \e offset
+    role specifies the position of the page in respect to the current page (0). A positive number
+    indicates that the page was visited after the current page, whereas a negative number indicates
+    that the page was visited before the current page.
+
+    The data models can also be used to create a menu, as illustrated by the following code
+    snippet:
+
+    \quotefromfile webenginequick/quicknanobrowser/BrowserWindow.qml
+    \skipto ToolBar
+    \printuntil onObjectRemoved
+    \printuntil }
+    \printuntil }
+    \printuntil }
+

+    \qmltype WebEngineDownloadRequest
+    \instantiates QWebEngineDownloadRequest
+    \inqmlmodule QtWebEngine
+    \brief Provides information about a download.
+
+    WebEngineDownloadRequest models a download throughout its life cycle, starting
+    with a pending download request and finishing with a completed download. It
+    can be used, for example, to get information about new downloads, to monitor
+    progress, and to pause, resume, and cancel downloads.
+
+    Downloads are usually triggered by user interaction on a web page. It is the
+    WebEngineProfile's responsibility to notify the application of new download
+    requests, which it does by emitting the
+    \l{WebEngineProfile::downloadRequested}{downloadRequested} signal together
+    with a newly created WebEngineDownloadRequest. The application can then examine
+    this item and decide whether to accept it or not. A signal handler must
+    explicitly call accept() on the item for \QWE to actually start
+    downloading and writing data to disk. If no signal handler calls accept(),
+    then the download request will be automatically rejected and nothing will be
+    written to disk.
+
+    \note Some properties, like the \l path under which the file will be saved,
+    can only be changed before calling accept().
+
+    \section2 Object Life Cycle
+
+    All items are guaranteed to be valid during the emission of the
+    \l{WebEngineProfile::downloadRequested}{downloadRequested} signal. If
+    accept() is \e not called by any signal handler, then the item will be
+    deleted \e immediately after signal emission. This means that the
+    application \b{must not} keep references to rejected download items.
+
+    \section2 Web Page Downloads
+
+    In addition to normal file downloads, which consist simply of retrieving
+    some raw bytes from the network and writing them to disk, \QWE also
+    supports saving complete web pages, which involves parsing the page's HTML,
+    downloading any dependent resources, and potentially packaging everything
+    into a special file format (\l savePageFormat). To check if a download is
+    for a file or a web page, use \l isSavePageDownload.

+    \qmltype webEnginePermission
+    \instantiates QWebEnginePermission
+    \inqmlmodule QtWebEngine
+    \brief An object used to access and modify the state of a single permission that's been
+    granted or denied to a specific origin URL.
+
+    The typical usage pattern is as follows:
+    \list 1
+        \li A website requests a specific feature, triggering the WebEngineView::permissionRequested signal;
+        \li The signal handler triggers a prompt asking the user whether they want to grant the permission;
+        \li When the user has made their decision, the application calls \l grant() or \l deny();
+    \endlist
+
+    Alternatively, an application interested in modifying already granted permissions may use WebEngineProfile::listPermissions()
+    to get a list of existing permissions associated with a profile, or WebEngineProfile::getPermission() to get
+    a webEnginePermission object for a specific permission.
+
+    The \l origin property can be used to query which origin the webEnginePermission is associated with, while the
+    \l feature property describes the associated feature. A website origin is the combination of its scheme, hostname,
+    and port. Permissions are granted on a per-origin basis; thus, if the web page \c{https://www.example.com:12345/some/page.html}
+    requests a permission, it will be granted to the origin \c{https://www.example.com:12345/}.
+
+    The usability lifetime of a webEnginePermission is tied either to its associated WebEngineView
+    (for transient feature types), or WebEngineProfile (for permanent feature types). A transient permission is one which
+    needs to be explicitly granted or denied every time it's needed (e.g. webcam/screen sharing permission), whereas a permanent
+    one might be stored inside the current profile, depending on the value of WebEngineProfile::persistentPermissionsPolicy.
+    You can check whether a webEnginePermission is in a valid state using its \l isValid() property. For invalid objects, calls to \l grant(),
+    \l deny(), or \l reset() will do nothing, and their \l state() will always be WebEnginePermission.Invalid.
+
+    The feature types Qt WebEngine supports are described in \l feature.

+    not accessible from a different one. The worldId property provides some predefined IDs for this
+    purpose.
