[Paraview] Trouble with "information_only" GUI property in paraview filter

[Yumin Yuan]

Hi Alex,

If you can debug into pqNamedWidgets::createWidgets(), and see where
and why this property is being skipped, it will help to narrow down
the problem, especially around this piece of logic (starting with line
892).


    // skip information properties
    if((!propertiesToShow.contains(propertyName) && informationOnly) ||
        SMProperty->GetIsInternal())
      {
      continue;
      }

    vtkPVXMLElement *hints = SMProperty->GetHints();

    // skip non-summary properties if summaryOnly is true
    if(summaryOnly && (!hints ||
hints->FindNestedElementByName("ShowInSummaryPanel") == 0))
      {
      continue;
      }


HTH,
Yumin
