Hello Alessandro:
It may be possible but it's not obvious to me. I suspect I can use the
ArrayListDomain xml element but I don't quite understand how it works. I
also don't have time right now to dive into the PV source code.
I do see from the Threshold filter:
<DoubleVectorProperty command="ThresholdBetween"
default_values="0 0"
label="Threshold Range"
name="ThresholdBetween"
number_of_elements="2"
panel_widget="double_range">
<ArrayRangeDomain name="range">
<RequiredProperties>
<Property function="Input"
name="Input" />
<Property function="ArraySelection"
name="SelectInputScalars" />
</RequiredProperties>
</ArrayRangeDomain>
</DoubleVectorProperty>
Perhaps someone from the Paraview development team can chime in on this
issue? I'll be happy to add it once I understand how it actually works.
Thanks,
Shuhao

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

Hello Alessandro,
I just published a library that allows you to do _just this_. See:
https://github.com/shuhaowu/pvpyfilter
The example covers exactly this and specifically you can use the property:
double_slider = Double("double with slider", default=0.5, slider=[0.0,
1.0], help="double with slider between 0.0 and 1.0 and a default of 0.5")
Let me know if the library works for you or if you encounter any bug as it
is still early days for this library.
Cheers,
Shuhao

Hello,
I'm trying to write a plugin based on a programmable filter in order to
extract a single block from a multiblockdataset (with a single level
tree)
in input chosing it through a slider in the property panel.
I need help to automatically set the range of the slider (the higher
limit
as the lower is always 0) as the number of blocks of the
multiblockdataset
in input, but the XML ServerManager definition of the slider is not clear
enough for me.
I'm trying to follow Utkarsh suggestion in
https://public.kitware.com/pipermail/paraview/2009-March/011599.html
but I'm missing how to recovery the number of blocks of the input of the
programmable filter and how to set it as the upper value of the slider
range.
Thank you in advance for your kind help
Alessandro
