Detailed Description

       will be deleted in the destructor of the dictionary.

Member Function Documentation

   bool QwtPlotDict::autoDelete () const Returns:
           true if auto deletion is enabled

       See also:
           setAutoDelete(), attachItem()

   void QwtPlotDict::detachItems (intrtti = QwtPlotItem::Rtti_PlotItem, boolautoDelete = true) Detach items from
       the dictionary
       Parameters:
           rtti In case of QwtPlotItem::Rtti_PlotItem detach all items otherwise only those items of the type
           rtti.
           autoDelete If true, delete all detached items

   QwtPlotItemList QwtPlotDict::itemList (intrtti) const Returns:
           List of all attached plot items of a specific type.

       See also:
           QwtPlotItem::rtti()

   const QwtPlotItemList & QwtPlotDict::itemList () const
       A QwtPlotItemList of all attached plot items. Use caution when iterating these lists, as
       removing/detaching an item will invalidate the iterator. Instead you can place pointers to objects to be
       removed in a removal list, and traverse that list later.

       Returns:
           List of all attached plot items.

   void QwtPlotDict::setAutoDelete (boolautoDelete) En/Disable Auto deletion
       If Auto deletion is on all attached plot items will be deleted in the destructor of QwtPlotDict. The
       default value is on.
