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.
