Detailed Description
A dictionary for plot items.
QwtPlotDict organizes plot items in increasing z-order. If autoDelete() is enabled, all attached items will be deleted in the destructor of the dictionary. QwtPlotDict can be used to get access to all QwtPlotItem items - or all items of a specific type - that are currently on the plot.

bool QwtPlotDict::autoDelete () const
- Returns
true if auto deletion is enabled

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.

void QwtPlotDict::insertItem (QwtPlotItem * item) [protected]
Insert a plot item
- Parameters
item PlotItem

removeItem()
Definition at line 115 of file qwt_plot_dict.cpp.
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.

QwtPlotItemList QwtPlotDict::itemList (int rtti) const
- Returns
List of all attached plot items of a specific type.
- Parameters
rtti See QwtPlotItem::RttiValues

void QwtPlotDict::removeItem (QwtPlotItem * item) [protected]
Remove a plot item
- Parameters
item PlotItem
