autoDelete If true, delete all detached items
 

const QwtPlotItemList & QwtPlotDict::itemList () const

List of all attached plot items.
 

void QwtPlotDict::setAutoDelete (boolautoDelete) 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.
