[Paraview-developers] Filtered choice of attributes

[Utkarsh Ayachit]

Cornelis,

Glad to help :). To answer you latest question, you can add the new
class in the "SERVER_MANAGER_SOURCES" in the add_paraview_plugin()
call.
e.g.

 ADD_PARAVIEW_PLUGIN(
    ...
   SERVER_MANAGER_XML foo.xml
   SERVER_MANAGER_SOURCES vtkSMMyNewDomain.cxx
 )

A few things to remember:
1. Ensure your domain class name begins with "vtkSM"
2. In XML, use the name of the domain without the "vtkSM" prefix e.g.
"<MyNewDomain ... >"
