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.

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

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.

Definition at line 166 of file qwt_plot_dict.cpp.

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()

Definition at line 176 of file qwt_plot_dict.cpp.

void QwtPlotDict::removeItem (QwtPlotItem * item) [protected]

Remove a plot item

Parameters

item PlotItem

See also

insertItem()

Definition at line 126 of file qwt_plot_dict.cpp.

void QwtPlotDict::setAutoDelete (bool autoDelete)
