bool QwtPlotDict::autoDelete () const Returns: true if auto deletion is enabled See also: setAutoDelete(), attachItem() void QwtPlotDict::detachItems (intrtti = QwtPlotItem::Rtti_PlotItem, boolautoDelete = true) 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. 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. See also: autoDelete(), attachItem()
