Indeed the wrapper has not been generated correctly because it has quite specific semantics (sip expected that only one value is going to be returned). As a workaround, I've added another override in r14017 which can be handled automatically by sip: >>> layer.computeMinimumMaximumFromLastExtent(1) (0.0, 255.0) Cheers Martin _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
