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.

Constructor & Destructor Documentation

   QwtPlotDict::QwtPlotDict () [explicit]
       Constructor

       Auto deletion is enabled.

       See also:
           setAutoDelete(), attachItem()

   QwtPlotDict::~QwtPlotDict ()
       Destructor

       If autoDelete is on, all attached items will be deleted

       See also:
           setAutoDelete(), autoDelete(), attachItem()

Member Function Documentation

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

       See also:
           setAutoDelete(), attachItem()

   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

   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 (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.
