More likely you'd use getStateSet() to find out if the node already has a
StateSet associated.
<code>
for geode in geodes:
stateSet = geode.getStateSet()
if stateSet != null:
# Create private copy (shallow copy)
stateSet = new osg::StateSet(stateSet)
else:
# Create empty StateSet
stateSet = new osg::StateSet()
# Set copy or new StateSet to Geode
geode.setStateSet(stateSet)
# Setup PolygonMode on StateSet
polygonMode = stateSet.getAttribute(osg::StateAttribute::POLYGONMODE)
if polygonMode == null:
# Create and add PolygonMode
stateSet.setAttributeAndModes(new osg::PolygonMode)
</code>
The important bit is the 'stateSet = new osg::StateSet(stateSet)' line, which
creates a
copy of the shared StateSet, so that changes to this new StateSet don't affect
other nodes
in the scene graph.
