/**
* @short A helper class that saves and restores state of an EntityTreeView
*
* This class saves and restores the state of a QTreeView showing an EntityTreeModel,
* or whatever proxies are stacked on top of one. State so far means the current selection
* and expansion of the items and collections.
*
* The EntityTreeViewStateSaver is needed because populating the EntityTreeModel
* is asynchronous and finding the right point in time to restore the state is a
* difficult task that is hidden inside this class.
*
* Example:
*
* @code
*
* class MyWidget : public QWidget
* {
* public:
* MyWidget( QWidget* parent );
* ~MyWidget();
*
* ...
*
* private:
* KConfig *mGlobalConfig;
* QTreeView *mTreeView;
* Akonadi::EntityTreeViewStateSaver *mStateSaver;
* };
*
* MyWidget::MyWidget( QWidget *parent )
* : QWidget( parent )
* {
* mGlobalConfig = ...
* mTreeView = new QTreeView( this );
* ...
*
* mStateSaver = new Akonadi::EntityTreeViewStateSaver( mTreeView );
*
* KConfigGroup group( mGlobalConfig, "treeViewState" );
* mStateSaver->restoreState( group );
* }
*
* MyWidget::~MyWidget()
* {
* KConfigGroup group( mGlobalConfig, "treeViewState" );
* mStateSaver->saveState( group );
* }
*
* @endcode
*
* @author Volker Krause <vkrause@kde.org>
* @since 4.4
*
* @deprecated This class is deprecated. Use ETMViewStateSaver instead.
