Hi Stefano,
In addition to the good suggestions by Sebastien, you can get more information
for each Python object using the following approaches:
Let's say your object is called 'obj'
1. Get help:
help(obj)
2. You can list all its attributes (properties & functions) using:
dir(obj)
or, better readable
for element in dir(obj):
print element
3. Then, if your object is a SourceProxy (maybe even if it's a Proxy, I'm not
sure), you can list its properties like so:
for p in obj.ListProperties():
print p, obj.GetProperty(p)
4. Lastly, in the help on an object you can sometimes see that not all
documentation is provided and you are referred to a vtk* object. Download the
source code from ParaView and view the type header file to see the full
information.
Good luck,
Menno

Subject: Re: [Paraview] ParaView Scripting
Hi Sebastien,
Thank you for your recommendations.
I have already been through all those resources and I was not able to extract
very much useful information from them. The the 'trace' suggestion seems
promising. I can't quite get it to do what I want, but I'm sure it'll prove
useful in the future.
This is what using the trace gave me:
--------------------------------------------------------------------------------------------------------
try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()
a3dResults_vtu = XMLUnstructuredGridReader(
FileName=['/home/stefano/workspace/TestSimulations/3dpropagation/output/vtk_output/3dResults.vtu']
)
a3dResults_vtu.PointArrayStatus = ['V_000000', 'V_000001', 'V_000002',
'V_000003', 'V_000004', 'V_000005']
# From here, I don't even know how to do what I want to do manually
# At this point if I am in Paraview and I hit 'Animate' then it will animate
V_00000 only. But, in fact, V_000000 is timestep 0 of V, V_000001 is timestep 1
of V, etc...
# So I essentially want it to either interpret the arrays as such or output a
series of vtu files which I can then hopefully open 'together' (output*.vtu)
and animate that...?
--------------------------------------------------------------------------------------------------------
Also. I would still like to know where I can look up the functionality of, for
example, paraview.simple, for the future.
Stefano

Hi Stefano,
you can give a look at http://paraview.org/Wiki/ParaView and more precisely on:
http://paraview.org/Wiki/ParaView#Python_Scripting
http://paraview.org/Wiki/ParaView/Python_Scripting
http://paraview.org/Wiki/Python_GUI_Tools
Hope this could give you more insight... The trace can help you
convert UI interaction into script which can be manually tweaked for
your custom purpose.
