Detailed Description

Filter model which either hides all entities marked as trash, or the ones not marked. Subentities of collections marked as trash are also shown in the trash.

The Base model must be an EntityTreeModel and the EntityDeletedAttribute must be available.

Example:

 ChangeRecorder *monitor = new Akonadi::ChangeRecorder( this );
 monitor->itemFetchScope().fetchAttribute<Akonadi::EntityDisplayAttribute>(true);

 Akonadi::EntityTreeModel *sourcemodel = new Akonadi::EntityTreeModel(monitor, this);

 TrashFilterProxyModel *model = new TrashFilterProxyModel(this);
 model->setDynamicSortFilter(true);
 model->setSourceModel(sourcemodel);
