[Qgis-user] Query on QgsVectorLayer

[Christoph Jung]

Hello everyone,

I have a question concerning PyQGIS. Imagine there is a point layer accessed via QgsVectorLayer, i.e. no matter which data source it is. Is it possible to query this layer to get the point object with the highest/lowest x-value in its geometry (similar to max-/min-aggregate functions in SQL)? Or do  I have to iterate over all objects and compare the values by my own?

Sincerely,
Christoph
