[Paraview] Question about inheritance in paraview(vtk)

[Biao She]

Yes, I have done that in my .cxx file, but it doesn't work...
I also found a strange phenomenon. When I include the header files for
DICOMParser and DICOMAppHelper in the header file of my class, I got an
error said "it can't find those header files".

I am wondering if this is related to the paraview plug-in CMake file. I use
the following code in the CMake file to link the paraview (vtk) library:
FIND_PACKAGE(ParaView REQUIRED)
INCLUDE(${PARAVIEW_USE_FILE})

Maybe this isn't enough to link the DICOMParser and DICOMAppHelper in
paraview?
Thanks,

Biao
