Detailed Description
Comments can be retrieved by calling fetchCommentsAsync on a PortalItem and accessed via the {PortalItem::comments} {comments} list model property after the task is complete.
The model returns data for the following roles:
| Role | Type | Description | SublayerRoles |
|---|---|---|---|
| comment | QString | The text of the comment. | Portal |
| comment | QString | The I | Portal |
| created | QDate | The date the comment was created. | Portal |
| owner | QString | The username of the user that added the comment. | Portal |
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
}
