[Paraview-developers] How to find the selected object?

[Utkarsh Ayachit]

The easiest way would be as follows:

vtkSMProxySelectionModel* selModel = pqActiveObjects::instance().
activeSourcesSelectionModel();
for (unsigned int cc=0, max = selModel->GetNumberOfSelectedProxies();
      cc<max; cc++)
  {
  vtkSMProxy* item = selModel->GetSelectedProxy(cc);
  // item can be a vtkSMSourceProxy or a vtkSMOutputPort.
  }
