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.

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.
