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.
