setPresetOffest.py

def setPresetOffset(self, x, y, dontMoveFirstLast, presetsCombobox):
  volRenWidget = slicer.modules.volumerendering.widgetRepresentation()
  if volRenWidget is None:
    logging.error('Failed to access volume rendering module')
    return

  # Make sure the proper volume property node is set
  volumePropertyNode = presetsCombobox.mrmlVolumePropertyNode()
  if volumePropertyNode is None:
    logging.error('Failed to access volume properties')
