Could you explain what you mean with > 'conflicting with radio-on-groups' (what are 'radio-on-groups')? By 'radio-on-groups' I meant using radio behavior on groups rather than on layers. Having "selection type" as a parameter of a group solves the complexity problem I had in mind. --strk; _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
