I wrote a PYTHON plugin that does a simple feature select on a QgsVectorLayer:

pnt = <coordinates of mouse click on map >
myLayer= <QgsVectorLayer Object>
tolerance = 1
rectangle = QgsRectangle()
rectangle.setXMinimum (pnt.x() - tolerance)
rectangle.setXMaximum (pnt.x() + tolerance)
rectangle.setYMinimum (pnt.y() - tolerance)
rectangle.setYMaximum (pnt.y() + tolerance)
myLayer.select(rectangle , True)
  • in QGIS 1.6 this code works with both shapefiles and postgis layers,
  • in QGIS 1.7 it works ONLY in postgis layers, on shapefile layers it always returns 0 features.

I am attaching a ZIP of a test plugin with select() function.

On 1.7 it works ONLY on PostGIS layers, NOT on SHP/spatialite layers.
