Member Function Documentation

  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.
