Hi,
I'm a new QGIS developer. I want to create a graph, a network, with a vector line layer that represents the roads of a city, to find the shortest path between two points. Can you help me to transform the vector layer in a graph, or split the lines features of the layer in the in-node and out-node? How I have to use the qgis.core library, in particularly, the QgsGraph class? Greeting, raffalba
