    Detailed Description

    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:

    RoleTypeDescriptionPortalItemRoles
    urlQUrlThe URL for the resource represented by the item.PortalItemUrlRole
    itemIdQStringThe ID of the item.PortalItemItemIdRole
    accessPortalAccessThe level of access to the item.PortalItemAccessRole

    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
    }
