rttiIn case of QwtPlotItem::Rtti_PlotItem detach all items otherwise only those items of the type rtti.
autoDeleteIf true, delete all detached items
const QwtPlotItemList & QwtPlotDict::itemList ( ) const

A QwtPlotItemList of all attached plot items.

Returns:
List of all attached plot items.

Returns:
List of all attached plot items of a specific type.
