Detailed Description

Comments can be retrieved by calling fetchComments on a PortalItem and accessed via the {PortalItem::comments} {comments} method after the task is complete.

The model returns data for the following roles:

Role	Type	Description	SublayerRoles
comment	QString	The text of the comment.	PortalItemCommentCommentRole
commentId	QString	The ID of the comment.	PortalItemCommentCommentIdRole
created	QDateTime	The date the comment was created.	PortalItemCommentCreatedRole
owner	QString	The username of the user that added the comment.	PortalItemCommentOwnerRole

Example:

Accessing various roles of the model from within a QML delegate:

Text{
    anchors.fill: parent
    // acccess the comment, commentId, created and owner roles of the model
    text: "comment:" + comment + "; ID:" + commentId + "; created:" + created + "; owner: " + owner
    wrapMode: Text.WrapAnywhere
}
