# EntityTreeView Class Reference

`from PyKDE4.akonadi import *`

Inherits: QTreeView → QAbstractItemView → QAbstractScrollArea → QFrame → QWidget → QObject
Namespace: Akonadi

## Detailed Description

A view to show an item/collection tree provided by an EntityTreeModel.

When a KXmlGuiWindow is passed to the constructor, the XMLGUI defined context menu akonadi_collectionview_contextmenu or akonadi_itemview_contextmenu is used if available.

Example:

     using namespace Akonadi;

     class MyWindow : public KXmlGuiWindow
     {
       public:
        MyWindow()
          : KXmlGuiWindow()
        {
          EntityTreeView *view = new EntityTreeView( this, this );
          setCentralWidget( view );

          EntityTreeModel *model = new EntityTreeModel( ... );
          view->setModel( model );
        }
     }
