[Paraview] XML plugin based on programmable filter with a slider

[Alessandro De Maio]

Hello  Shuhao,
   thank you for your reply and for your really great job on the
pvpyfilter. I had already tried it and it's very useful.
But I'm looking for the possibility to automatically assign the slider
range (in this case the upper value will be enough) depending on
information about the input of the programmable filter (in this case the
number of blocks of a multiblock dataset) and not to set it hardcoded in
the xml as from your approach. I would like that, if I apply this filter to
a mbdataset with 5 blocks, the slider can choose an int value from 0 to 4,
and if I apply the same filter (without modifying xml) to another mbdataset
with 8 blocks the slider provides an int from 0 to 7.

Cheers

Alessandro

PS With pvpyfilter is there the possibility of decide in the .py file the
order of the widgets in the property panel? It seems to me that the order
is random
