QList<QVariant> blocks;

}
pqSMAdaptor::setMultipleElementProperty(

this->Pipeline->UpdateProperty("BlockIndices");
assuming you're inside a pqSomething class and have access to all the usual
pqSMAdaptor stuff. From raw servermanager stuff it'd look different

Subject: [Paraview] vtkSMIntVectorProperty number of elements
Hi, all
I have built a Toolbar plugin in paraview with a button that applies
extractblock filter to a multiblock dataset
so as to get all the blocks seperately in different objects in the pipeline
browser.
I achieve getting the number of blocks from the selected multiblock but I don't
know how to set the block indice
of an extract block filter after having it buit.
vtkSMProperty* property= [the pqPipelineSource resulting from
createFilter]->GetProperty("BlockIndices");
vtkSMIntVectorProperty * indices=
vtkSMIntVectorProperty::SafeDownCast(property);
but "indices->GetNumberOfElements();" returns 0 while the compositeTreeWidget
displays the blocks' hierarchy.
how can I modify a vtkSMProperty within the code?
thanks in advance!
