Detailed Description

A proxy model that exposes collection statistics through extra columns.

This class can be used on top of an EntityTreeModel to display extra columns summarizing statistics of collections.

Akonadi::EntityTreeModel *model = new Akonadi::EntityTreeModel( ... );
 
Akonadi::StatisticsProxyModel *proxy = new Akonadi::StatisticsProxyModel();
proxy->setSourceModel( model );
 
Akonadi::EntityTreeView *view = new Akonadi::EntityTreeView( this );
view->setModel( proxy );
