Member Function Documentation

void QgsGraphBuilder::addArc ( int  pt1id,
const QgsPoint pt1,
int  pt2id,
const QgsPoint pt2,
const QVector< QVariant > &  properties 

add arc

pt1idfirst vertex identificator

propertiesarc properties
pt1id, pt1 and pt2id, pt2 is a redundant interface. You can use vertex coordinates or their identificators.

const QgsPoint pt 

add vertex
