Member Function Documentation

bool QwtPolarItemDict::autoDelete ( ) const

Returns: true if auto deletion is enabled

See also: setAutoDelete, attachItem

Definition at line 106 of file qwt_polar_itemdict.cpp.

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

Detach items from the dictionary

Parameters

rtti	In case of QwtPolarItem::Rtti_PlotItem detach all items otherwise only those items of the type rtti.
autoDelete	If true, delete all detached items

Definition at line 140 of file qwt_polar_itemdict.cpp.

void QwtPolarItemDict::insertItem ( QwtPolarItem * item )

protected

Insert a plot item

Parameters

item PlotItem

See also: removeItem()

Definition at line 117 of file qwt_polar_itemdict.cpp.

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.

Definition at line 168 of file qwt_polar_itemdict.cpp.

void QwtPolarItemDict::removeItem ( QwtPolarItem * item )

protected

Remove a plot item

Parameters

item PlotItem

See also: insertItem()

Definition at line 128 of file qwt_polar_itemdict.cpp.

void QwtPolarItemDict::setAutoDelete ( bool autoDelete )

En/Disable Auto deletion

If Auto deletion is on all attached plot items will be deleted in the destructor of QwtPolarItemDict. The default value is on.
