Hi,
I would like to see such an improved legend interface. Currently the
group and layer index even behaves differently between version 1.8 and
version 1.9. I have to check the version and decrease the index in case
it is version 1.9.
I use this horrible code to find a group and attach a new layer:
--------------------
#get the current group index of Schüler group
groups = []
for group in self.legend.groupLayerRelationship():
groups.append(group[0])
groupIndex = groups.index(groupName)
#move new layer to existing group
if QGis.QGIS_VERSION[0:3] >= "1.9":
groupIndex -= 1
self.legend.moveLayer(schoolDistrictLayer, groupIndex)
-------------------
Really horrible - this really should be a one-liner ... and not a
different behavior between QGIS versions for no good reason.

One option would be to store an unique identifier in each

each Legend incremented everytime a new group is added. Would this

any existing usage ? Are there tests for this in place ?
The advantage of this is that the interface of addGroup and
moveLayer would
not change.
I've a patch ready implementing a model similar to the above
(only difference is that the counter is a static within the group
class)
