detachItems()

void QwtPolarItemDict::detachItems	(	int	rtti = QwtPolarItem::Rtti_PolarItem,
		bool	autoDelete = true
	)

Parameters

rtti	In case of QwtPolarItem::Rtti_PlotItem detach all items otherwise only those items of the type rtti.

insertItem()

void QwtPolarItemDict::insertItem ( QwtPolarItem *  item )

protected

Parameters

item

PlotItem

itemList()

const QwtPolarItemList & QwtPolarItemDict::itemList

(

)

const

A QwtPolarItemList of all attached plot items.

Returns

List of all attached plot items.

Note

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.

removeItem()

void QwtPolarItemDict::removeItem ( QwtPolarItem *  item )

protected

Parameters

item
