Find closest segment to current end point and places the result in the supplied list (if segments are not already present)

virtual void DtTerrainSelector::collectAllSegments	(	int	iInterestRange,
		const DtNetworkEdge *	edge,
		QList< DtNetworkElement * > &	list,
		QList< DtNetworkSpecElement * > &	edges

const [inline, protected, virtual]

Reimplemented from DtSymbolSelector.

virtual void DtTerrainSelector::highlightSymbols

(

QVector< DtModelKey > *

display = 0

)

[protected, virtual]

Highlights any currently selected symbols.

Implements DtSymbolSelector.

virtual void DtTerrainSelector::updateTerrainModelData	(	QList< DtNetworkElement * > &	segments,
		bool	merge
	)		[protected, virtual]

Weeds out and create data that is (not) contained in the selected list.

If merge is true, will merge the current selection in with the existing as if a Ctrl or Shift keyboard button were pressed
