A PortalItem is a unit of content in the Portal. This type is populated by starting an operation to retrieve content and then can be accessed after the operation is complete. For example, the list of items can be retrieved by: querying the portal (such as with PortalQueryParametersForItems) or by fetching the featuredItems or by fetching the items belonging to a user.

The model returns data for the following roles:

Example: Accessing roles from a PortalItemListModel from within a QML delegate:

Text {
    anchors {
        fill: parent
        margins: 10
    }
    text: title // access the title role of the model
    color: "white"
    elide: Text.ElideRight
    wrapMode: Text.Wrap
    horizontalAlignment: Text.AlignHCenter
}
