[Paraview] SplineSource and python script
Hi,
I have some difficulties to have the SplineSource working properly
through a python script. First, I created a spline by hand and saved
the state as a python file. I simplified it in order to keep only the
SplineSource settings (file attached). When I execute this script
(ParaView-3.10-RC1), I get the following error :
Traceback (most recent call last):
File string, line 6, in module
File /usr/local/lib/paraview-3.10/site-packages/paraview/servermanager.py,
line 207, in __setattr__
to add this attribute.)
AttributeError: Attribute Closed does not exist. This class does not
allow addition of new attributes to avoid mistakes due to typos. Use
add_attribute() if you really want to add this attribute.
When I access the object through python shell, the Closed attribute
appears in a protected list (which seems to be the right case) :
FindSource(RCA).ParametricFunction.__dict__
{'SMProxy': (vtkSMProxy)0x48e25d0, '_Proxy__LastAttrName':
'NewPropertyIterator', '_Proxy__Properties': {'Points': weakref at
0x4ce6ec0; dead, 'Closed': weakref at 0x4ce6158; dead},
'ObserverTag': -1, 'Observed': None, 'Port': 0}
The same error occurs with the Points attribute, thus I cannot add
points by script : this is what I want to do.
Thanks !
Jerome

Re: [Paraview] SplineSource and python script
Hi Jerome,
It looks like the ParametricFunction property of the SplineSource is not
python friendly. I can confirm this bug. As a workaround, you can do this:
s.ParametricFunction.SetPropertyWithName(Closed, 1)
s.ParametricFunction.SetPropertyWithName(Points, [x,y,z, x2,y2,z2])
I think paraview will print an error message when you said the Points
property even though it works. You'll see an error message that the spline
must contain at least 1 point. My guess is that it clears the Points
property before setting the new value.

Re: [Paraview] SplineSource and python script
Hi,
It works like a charm! Thank you very much. You are right: I get the
expected error message, but the spline is correctly initialized.
