This model type is returned by:

Querying a Portal using PortalQueryParametersForGroups.
Accessing the featuredGroups of a Portal.
Calling fetchGroups with a PortalItem.

The model returns data for the following roles:

Example:

Access the various groups of a portalItem:

int adminGroupsCount = 0;
int memberGroupsCount = 0;
int otherGroupsCount = 0;

auto fetchGroupsFuture = portalItem->fetchGroupsAsync().then([portalItem, &adminGroupsCount, &memberGroupsCount, &otherGroupsCount]()
{
  // lambda function to iterate over PortalGroupListModels
  auto printGroupTitles = [](PortalGroupListModel* groupsModel, const QString& groupName)
  {
    if (!groupsModel)
    {
      return;
    }

    qDebug() << groupName << ":";
    for (int i = 0; i < groupsModel->rowCount(); ++i)
    {
      if (groupsModel->at(i))
      {
        qDebug() << groupsModel->at(i)->title();
      }
    }
  };

  printGroupTitles(portalItem->adminGroups(), "admin groups");
  printGroupTitles(portalItem->memberGroups(), "member groups");
  printGroupTitles(portalItem->otherGroups(), "other groups");
  adminGroupsCount = portalItem->adminGroups()->rowCount();
  memberGroupsCount = portalItem->memberGroups()->rowCount();
  otherGroupsCount = portalItem->otherGroups()->rowCount();
});

Example:

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

Image {
    source: thumbnailUrl // use the thumbnailUrl role of the model
    fillMode: Image.PreserveAspectCrop
    height: parent.height
    width: height
}

Text {
    text: title // access the title role of the group
    font.bold: true
}
