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.

Member Function Documentation
bool QwtPlotDict::autoDelete () const
Returns:
true if auto deletion is enabled
See also:
setAutoDelete() , insertItem()
void QwtPlotDict::detachItems (int rtti = 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
void QwtPlotDict::insertItem (QwtPlotItem * item) [protected]
Insert a plot item
Parameters:
item PlotItem
See also:
removeItem()
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
See also:
QwtPlotItem::rtti()
void QwtPlotDict::removeItem (QwtPlotItem * item) [protected]
Remove a plot item
Parameters:
item PlotItem
See also:
insertItem()
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.
