[Paraview] vtkSMProperty and vtkSet

[papa ndéné NDIAYE]

*Hi Utkarsh,

I just wanted to modify the BlockIndices property of the extract filter on
the fly.
  Since in the source code it is linked to a vtkstd::Set attribute in the
extractblock class,
I was trying to create a set vtkSet and put it in a vtkSMProperty so that I
just had to
call getProperty method and set the property pointer to the @ of my created
vtkSMProperty.
but with help from John Biddiscomb I got the way to do it.
It's something like:

QList<QVariant> blocks;*

*      vtkPVCompositeDataInformation *pvcdi = out->GetDataInformation()->
GetCompositeDataInformation();*

*      QList<QVariant> blocks;*

*      int N = pvcdi->GetNumberOfChildren();*

*      for (int i=0; i<N; i++) {*

*        if (...) blocks.append(i+1);*

*      }*

*      pqSMAdaptor::setMultipleElementProperty(*

*        this-> Pipeline->GetProperty("BlockIndices"), blocks);  *

*      this->Pipeline->UpdateProperty("BlockIndices");*

Great thanks for the interest you gave to my request!

Regards

Papa
