Detach items from the dictionary
- Parameters
- 
  
    | rtti | In case of QwtPolarItem::Rtti_PlotItem detach all items otherwise only those items of the type rtti. |  | autoDelete | If true, delete all detached items |  
 
 
 
      
        
          | 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.
