I'm having trouble adding the addChildAddedDagPathCallback on a newly
created node.
Writing a simple node (.py) and want to register a callback when a child is
parented under the node.
The node at the creation time is a shape node but I want to register the
callback to its parent transform
def postConstructor(self):
nodeFn = OpenMaya.MFnDependencyNode(self.thisMObject())
nodeFn.setName("%sShape#" % self.typeName())
dpath = OpenMaya.MDagPath()
OpenMaya.MDagPath.getAPathTo(self.thisMObject(), dpath)
dpath.transform()
self._cbchild = OpenMaya.MDagMessage.addChildAddedDagPathCallback( dpath,
self._childAdded, nodeFn )
The transform is not recognized at the time when the callback is created so
the path is invalid.
Any workaround? Or am I doing it wrong?
Thanks!
