Hi Patrick,
Have you tried adding a StringVectorProperty to your XML for a
filename (with <FileListDomain name="files"/>) and having a GUI XML
file for adding a reader? I think someone suggested you look at the
helix source xml
(http://paraview.org/gitweb?p=ParaView.git;a=blob;f=Examples/Plugins/HelixSource/helix.xml;h=d6c385561d9cdffc5298ced17d700bae8bc167b6;hb=HEAD)
and you can see how to add the GUI XML file in the other reader
example
(http://paraview.org/gitweb?p=ParaView.git;a=tree;f=Examples/Plugins/Reader;hb=HEAD)
Hi Paul,
Thanks to share your experience on this topic.
As I wrote to another paraview user,
my python code is a small 200 lines using netCDF4, numpy
and its conversion is not as straightforward as it could be because I use
many numpy functions.
Of course, I can do it but the python approach is more attrative.
I have tried to add
<StringVectorProperty
name="FileName"
animateable="0"
command="SetFileName"
number_of_elements="1">
<FileListDomain name="files"/>
</StringVectorProperty>
to the helix.xml example but
when I load it nothing appears in the source menu.
What I would like is a Python Reader example.
If someone has this to share, I am very interested.
Patrick
