       Detach items from the dictionary

       Parameters
           rtti In case of QwtPolarItem::Rtti_PlotItem detach all items
           otherwise only those items of the type rtti.

   void QwtPolarItemDict::insertItem (QwtPolarItem * item) [protected]
       Insert a plot item

       Parameters
           item PlotItem

       See also
           removeItem()

       Definition at line 117 of file qwt_polar_itemdict.cpp.

   const QwtPolarItemList & QwtPolarItemDict::itemList () const
       A QwtPolarItemList of all attached plot items.

       Returns
           List of all attached plot items.

       Note
           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.

   void QwtPolarItemDict::removeItem (QwtPolarItem * item) [protected]
