Detailed Description

Folders are used to organize content in a portal. The list of PortalFolder objects is retrieved by calling fetchContent and if the operation is succesful, this model is returned by the portalUser's folders method.

Multilevel folders are not supported in a portal.

The model returns data for the following roles:

Role	Type	Description	SublayerRoles
created	QDateTime	The date the folder was created.	PortalFolderCreatedRole
folderId	QString	The ID of the folder.	PortalFolderFolderIdRole
title	QString	The title of the folder.	PortalFolderTitleRole

Example:

Retrieve the model representing a user's folders:

// fetch the portal user's folders
QMap<QString, QString> folderTitles; // folderId and folderTitle

connect(&portalUser, &PortalUser::fetchContentCompleted, this, [&portalUser, &folderTitles](bool success)
        {
          if (!success)
          {
            return;
          }

          PortalFolderListModel* folders = portalUser.folders();
          Q_CHECK_PTR(folders);

          for (auto&& i : *folders)
          {
            PortalFolder folder = i;
            folderTitles[folder.folderId()] = folder.title();
            qDebug() << folder.title();
          }
        });

portalUser.fetchContent();
