Maybe it is possible with a method that takes the tolerance in pixels, the point where the user clicked and the layer involved. The method then would calculate the search rectangle in layer coordinates.

Can't we reffer to the reprojected coordinates? Maybe it's something to add to the API? _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
