Thanks!
Would it be also possible to get it setup so we can override the files in the
state file upon loading, just as is done with the GUI? I was going to try and
implement this myself, but after spending 6 hours trying to track through the
code to figure out how it works, I'm stumped. My first adventure into VTK and
Paraview guts didn't go so well...
For that to work, I guess there would need to be an extra step in the process.
First would be to load the state file but not execute anything. Then modify the
XML tree as desired, then update the pipeline.
The most flexible way to do it (because it would allow changes to things other
than filenames) is to have a dictionary you can specify the id and the value.
For instance:
{'278.FileName': 'MyFile',
'278.CellArrayStatus.array_list':['Pressure','Temperature']}
etc.. That would have to be passed through a function since I assume we can't
expose the actual information directly to the user since it resides on the
server and not the client.
Has anybody thought about this recently? I saw it had been discussed and given
up on a year ago... I will keep trying to figure out how the code works in my
spare time, but it will probably be a long time before I figure it out.
