[Paraview] Python programmable script and XML SetInputArrayToProcess to get array name

[THIBON Alfred]

Dear Paraviewers,

I am kind of a newby and can't figure out how to access in a custom plugin the string with the name of a scalar field from an input.

I followed informations in Pat Marion's page https://blog.kitware.com/easy-customization-of-the-paraview-python-programmable-filter-property-panel/ and add a snippet from http://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Drop_down_list_with_values_from_input_arrays.

But if I managed to use variables from a DoubleVectorProperty by calling its name property from my script, I can't figure out how to access the name of my arrays in the StringVectorProperty populated with SetInputArrayToProcess command.

Maybe I am not using the right tools. My goals is to get the string name of my array to read pointdata.
Today I can access it by hardcoding the name in my programmable script :

self.array = 'CHAMP___ACCELERATION___001'
inputs[0].PointData[self.array][:,0]

I'd like to get  'CHAMP___ACCELERATION___001' from a drop down list. With the following snippet the list is populated but I can't access the string selected. That must be simple...

      <StringVectorProperty name="SelectInputScalars"
                          label="Array"
                          command="SetInputArrayToProcess"
                          number_of_elements="5"
                          element_types="0 0 0 0 2"
                          animateable="0">
        <ArrayListDomain name="array_list"
                         attribute_type="Scalars"
                         input_domain_name="inputs_array">
          <RequiredProperties>
            <Property name="Input"
                      function="Input" />
          </RequiredProperties>
        </ArrayListDomain>
        <FieldDataDomain name="field_list">
          <RequiredProperties>
            <Property name="Input"
                      function="Input" />
          </RequiredProperties>
        </FieldDataDomain>
      </StringVectorProperty>

I am not sure my message (and my English) are very clear...

Thank you very much for your incoming help !

Alfred
