## Detailed Description

WebEngineScriptCollection handles a user scripts collection, which is injected in the JavaScript engine during the loading of web content.

Use WebEgineView.userScripts and 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 WebEngineScriptCollection.collection property or by WebEngineScriptCollection methods.

Note: The new user script can be instantiated with JavaScript dictionaries when using collection property.

See the following code snippets demonstrating the usage:

- collection property with JavaScript dictionaries

       var scriptFoo = { name: "Foo",
                       sourceUrl: Qt.resolvedUrl("foo.js"),
                       injectionPoint: WebEngineScript.DocumentReady }

       webEngineView.userScripts.collection = [ scriptFoo, scriptBar ];

- collection property with user script object as value type

       var script = WebEngine.script()
       script.name = "FOO"
       webEngineView.userScripts.collection = [ script ]

- user script collection insert method can be used only with value type or list of value types

       var script = WebEngine.script()
       script.name = "FOO"
       webEngineView.userScripts.insert(script)

       var list = [ script ]
       webEngineView.userScripts.insert(list)
