I want to generate a script for getting statistic information window from selected feature. For example i have two layer building(polygon) and railway(linestring). By using this tools i got a window dialog that shows me total number of features, total lenght of railways maybe... Exactly i need windows/dialog screens examples for Sextante. But lots of tutorials are about algorithms.
Here is an example windows that generated by using "Basic statistics for numeraic fields" tool from Sextante/QGIS geoalgorithms/Vector table tools
