Hi.
Question about the groups and layers in the python  plug-in for (Qgis 
v.1.6)
#I created several groups.
grp1 = qgis.utils.iface.legendInterface (). addGroup ("grp1", -1)
grp2 = qgis.utils.iface.legendInterface (). addGroup ("grp2", -1)
#I created a layer of
vlayer = QgsVectorLayer ('c: \ data \ zu.tab', 'Zu', 'ogr')
#Move the layer into the group
QgsMapLayerRegistry.instance (). MoveLayer (vlayer, grp2)

How can I change the nesting of groups using Python?

ps
Sorry for the language
