QgsVectorLayer class is more complex that its raster equivalent. To describe it, we will first approach basic layer parameters and then we will explore how the vector is organized. We will explore some classes that are involved in the vector structure that represent rows and headers.
We will explore the vector class working on a real vector; we will load
alaska.shp in the
This variable is an instance of the
QgsVectorLayer class. This means that all methods of the vector are documented at http://qgis.org/api/classQgsVectorLayer.html. As for rasters, this class is a specialization of the generic
To get the extent of the layer, it's necessary to use the
extent() method ...
