Detailed Description

A delegate that draws unread and total count for CollectionStatisticsModel.

The delegate provides the following features:

  • Collections with unread items will have the foldername and the unread column marked in bold.
  • If a folder is collapsed, the unread and the total column will contain the total sum of all child folders
  • It has the possibility to draw the unread count directly after the foldername, see toggleUnreadAfterFolderName().

Example:

 Akonadi::EntityTreeView *view = new Akonadi::EntityTreeView( this );

 Akonadi::StatisticsProxyModel *statisticsProxy = new Akonadi::StatisticsProxyModel( view );
 view->setModel( statisticsProxy );

 Akonadi::CollectionStatisticsDelegate *delegate = new Akonadi::CollectionStatisticsDelegate( view );
 view->setItemDelegate( delegate );
Note:
This proxy model is intended to be used on top of the EntityTreeModel. One of the proxies between the EntityTreeModel (the root model) and the view must be a StatisticsProxyModel. That proxy model may appear anywhere in the chain.
