Member Function Documentation

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

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.
