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:
| Role | Type | Description | PortalItemRoles |
|---|---|---|---|
| url | QUrl | The URL for the resource represented by the item. | PortalItemUrlRole |
| itemId | QString | The ID of the item. | PortalItemItemIdRole |
| access | PortalAccess | The level of access to the item. | PortalItemAccessRole |
| accessAndUseConstraintsHtml | QString | The access and use constraints HTML. | PortalItemAccessAndUseConstraintsHtmlRole |
| averageRating | int | The average rating of the item. | PortalItemAverageRatingRole |
| commentCount | int | The number of comments for the item. | PortalItemCommentCountRole |
| commentsEnabled | bool | Whether comments are allowed on the item. | PortalItemCommentsEnabledRole |
| culture | QString | The item locale information (language and country). | PortalItemCultureRole |
| folderId | QString | The ID of the folder containing the item. | PortalItemFolderIdRole |
| name | QString | The name of this item. | PortalItemNameRole |
| owner | QString | The username of the user who owns the item. | PortalItemOwnerRole |
| ratingCount | int | The number of ratings received by the item. | PortalItemRatingCountRole |
| serviceUrl | int | The service URL for the item. | PortalItemServiceUrlRole |
| size | qint64 | The size of the item in bytes. | PortalItemSizeRole |
| type | PortalItemType | The type of the item. | PortalItemTypeRole |
| typeKeywords | QStringList | A set of keywords that further describes the type of the item. | PortalItemTypeKeywordsRole |
| typeName | QString | The name of the type of this item. | PortalItemTypeNameRole |
| viewCount | int | The number of times this item has been viewed. | PortalItemViewCountRole |
| description | QString | The item description. | PortalItemDescriptionRole |
| extent | Envelope | The bounding rectangle of the item. | PortalItemExtentRole |
| snippet | QString | The short summary description of the item. | PortalItemSnippetRole |
| title | QString | The title of the item. | PortalItemTitleRole |

| thumbnailUrl | QUrl | The thumbnail of the item as a local file URL. | PortalItemThumbnailUrlRole |
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
