Hi,
I am not sure we should make any publicity to the legend API which is
very bad.
I hope these methods will deprecated soon ;)
I think any change making the handling of groups easier is appreciated.

Hi,
Thank you Bernhard. This works better than my code with the
legend.groupLayerRelationship()
We should add this to the Python Cookbook
(http://www.qgis.org/en/docs/pyqgis_developer_cookbook/) - Do you mind?
Or should I do a pull request?
Do you have a clever strategy to make this same code available in
multiple QGIS plugins?
But really this should go into the core QGIS API. It is annoying taking
care of such things.

Hi Andreas,
this is how I do it:
def getGroupIndex(self, groupName):
'''Find the index for group groupName'''
retValue = -1
groups = self.iface.legendInterface().groups()
for i in range(len(groups)):
if groups[i] == groupName:
retValue = i
break
return retValue
def moveToGroup(self, layer, groupName):
'''move layer into a group'''
grpIdx = self.getGroupIndex(groupName)
if grpIdx == -1:
# add the group
grpIdx = self.iface.legendInterface().addGroup(groupName)
self.iface.legendInterface().moveLayer(layer, grpIdx)

Hi,
In my python script I would like to append a filtered Postgis layer
into
a group with a given name.
This works fine as long as the user did not activate a group already
interactively. If a group is already active, my method to find the
groupIndex fails. If not group is active, the script works fine.
Here is my method:
---------------
#read the legend tree to find the index of the group defined in
groupName
groups = []
for group in self.legend.groupLayerRelationship():
groups.append(group[0])
groupIndex = groups.index(groupName)
if QGis.QGIS_VERSION[0:3] >= "1.9":
groupIndex -= 1
#move new layer to existing group
self.legend.moveLayer(schulkreisLayer, groupIndex)
--------------
Is there a more reliable way to find the groupIndex if the user
selected
a group already?
Maybe there is some interference with the setting "New layers should be
added to chosen or current group" setting in "Settings" --> "Options"
--> "Map & Legend" --> "Layerlegend"?
Thanks,
Andreas
