See also:
setAutoDelete(), attachItem()

Destructor
If autoDelete is on, all attached items will be deleted
See also:

Returns:
true if auto deletion is enabled
See also:
setAutoDelete(), attachItem()

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

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:

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.
