<p>Following the example in the wiki (<a href="https://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Drop_down_list_with_values_from_input_arrays" class="OWAAutoLink" id="LPlnk323110" previewremoved="true">https://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Drop_down_list_with_values_from_input_arrays</a>)
I can add a dropdown to my xml plugin to grab an array to process with a programmable filter. But I want to process two arrays. How can I do this? It's obviously related to the "idx" parameter of SetInputArrayToProcess in vtkAlgorithm but I can't figure
out how to make the paraview GUI cooperate.</p>
