[vtkusers] How to use vtkDataObjectReader in C++

[ycollette.nospam at free.fr]

Hello,

Thanks for all these advices. Now it works:

bool VTKContainer::read_file(const char * Filename)
{
  //vtkDataObjectReader * do_reader = vtkSmartPointer<vtkDataObjectReader>::New();
  vtkDataObjectReader * do_reader = vtkDataObjectReader::New();
  
  do_reader->SetFileName(Filename);

  do_reader->ReadAllFieldsOn();
  
  dataSet = do_reader->GetOutput()->GetFieldData();
  
  return (dataSet!=NULL);
}

There is still 1 thing:
- The smart pointer version doesn't work: it hangs when calling SetFileName.

Once you get this working it would be great if you could make a short
example an post it on the wiki:
