Technicallywhat you have commented out in your Node.setName() could work
just fine if you want manage your maya calls directly from the Node objects:
class Node(object):
....
def setName(self, name):
print self._name, name
cmds.rename(self._name, name)
self._name=name
To me, it seems appropriate to do it from the model/items since what you
are modeling is the SceneGraph and you have the most context between the
model and the data you are representing. The alternative is to emit the
signals from your model and handle them in some other slot:
def setData(self, index, value, role=QtCore.Qt.EditRole):
if index.isValid():
if role ==QtCore.Qt.EditRole:
node = index.internalPointer()
oldName = node.name()
node.setName(value)
self.dataChanged.emit(index, index)
self.nameChanged.emit(node, oldName, value)
return True
return False
# some other function or method as a slot
def nodeNameChanged(node, oldName, newName):
print node, "name was changed from", oldName, "to", newName
cmds.rename(oldName, newName)
myModel = SceneGraphModel()
myModel.nameChanged.connect(nodeNameChanged)
It might be much cleaner though to go with the first and keep all the
SceneGraph <=> Model logic together, so that you can have multiple views
and not have to duplicate any logic.
