void QgsLabelSearchTree::clear ( )

Removes and deletes all the entries.

bool QgsLabelSearchTree::insertLabel	(	pal::LabelPosition *	labelPos,
		int	featureId,
		const QString &	layerName,
		const QString &	labeltext,
		const QFont &	labelfont,
		bool	diagram = `false`,
		bool	pinned = `false`
	)

Inserts label position.

Does not take ownership of labelPos

Definition at line 78 of file qgslabelsearchtree.cpp.

void QgsLabelSearchTree::label	(	const QgsPoint &	p,
		QList< QgsLabelPosition * > &	posList
	)		const

Returns label position(s) at a given point.

QgsLabelSearchTree keeps ownership, don't delete the LabelPositions

Note: not available in python bindings TODO: why does this break bindings with QList<QgsLabelPosition>?

Definition at line 34 of file qgslabelsearchtree.cpp.

void QgsLabelSearchTree::labelsInRect	(	const QgsRectangle &	r,
		QList< QgsLabelPosition * > &	posList
	)		const

Returns label position(s) in given rectangle.

QgsLabelSearchTree keeps ownership, don't delete the LabelPositions

Note: not available in python bindings TODO: why does this break bindings with QList<QgsLabelPosition>?
