Detailed Description

       A dictionary for plot items.

       QwtPlotDict organizes plot items in increasing z-order. If autoDelete() is enabled, all attached items
       will be deleted in the destructor of the dictionary. QwtPlotDict can be used to get access to all
       QwtPlotItem items - or all items of a specific type - that are currently on the plot.

Constructor & Destructor Documentation

   QwtPlotDict::QwtPlotDict () [explicit]
       Constructor

       Auto deletion is enabled.

       See also:
           setAutoDelete(), QwtPlotItem::attach()

   QwtPlotDict::~QwtPlotDict () [virtual]
       Destructor

       If autoDelete() is on, all attached items will be deleted

       See also:
           setAutoDelete(), autoDelete(), QwtPlotItem::attach()

Member Function Documentation

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

       See also:
           setAutoDelete(), insertItem()

   void QwtPlotDict::detachItems (int rtti = QwtPlotItem::Rtti_PlotItem, bool autoDelete = 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

   void QwtPlotDict::insertItem (QwtPlotItem * item) [protected]
       Insert a plot item

       Parameters:
           item PlotItem

       See also:
           removeItem()

   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.

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

       Parameters:
           rtti See QwtPlotItem::RttiValues

       See also:
           QwtPlotItem::rtti()

   void QwtPlotDict::removeItem (QwtPlotItem * item) [protected]
       Remove a plot item

       Parameters:
           item PlotItem

       See also:
           insertItem()

   void QwtPlotDict::setAutoDelete (bool autoDelete)
       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.
