    \brief Allows configuration of browser properties and attributes.

    The WebEngineSettings type can be used to configure browser properties and generic
    attributes, such as JavaScript support, focus behavior, and access to remote content. This type
    is uncreatable, but the default settings for all web engine views can be accessed by using
    the \l [QML] {WebEngine::settings}{WebEngine.settings} property.

    Each web engine view can have individual settings that can be accessed by using the
    \l{WebEngineView::settings}{WebEngineView.settings} property.
