[Paraview-developers] [EXTERNAL] Deprecating old-panels from ParaView

[Utkarsh Ayachit]

John,

You can find  the pqPipelineRepresentation corresponding to the proxy
using the following:

pqServerManagerModel* smmodel =
pqApplicationCore::instance()->getServerManagerModel();
pqPipelineRepresentation* repr =
smmodel->findItem<pqPipelineRepresentation*>(proxy);

But note as you noted, both the proxy passed into the constructor of
the pqPropertyWIdget as well as the pqPipelineRepresentation* returned
by the above code will correspond to the "outer" representation i.e.
the "UniformGridRepresentation" and not the "OpacityRepresentation".
That behavior has hasn't changed. The pqPipelineRepresentation
accessible by the add_display_panel_decorator(...) was indeed
corresponding to the "outer" representation.
