In your .cxx file add #include "vtkDICOMImageReaderVector.h" and the
other classes that are just forward declared in the header file.

Hi everyone. This might be a silly question, but I am really confused.
I am writing a class inherites from vtkDICOMImageReader. In the
header file of vtkDICOMImageReader class, there are some forward
declaration of these classes: vtkDICOMImageReaderVector, DICOMParser
and DICOMAppHelper. The definition of these classes are included in
the .cxx file. Normally, I should be able to use the methods in
those classes in my class. However, I found that whenever I want to
use something like "this->Parser->ClearAllDICOMTagCallbacks()" in my
class. The compiler gives me back an error says that "invalid use of
undefined type 'structure DICOMParser". In the above, "Parser" is an
instance of DICOMParser. The same situation also happen to
DICOMAppHelper and vtkDICOMImageReaderVector.
Thanks very much for any of your help.
