| Since: | QtWebEngine 1.1 |
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 WebEngine.settings property.
Each web engine view can have individual settings that can be accessed by using the WebEngineView.settings property.
