[vtkusers] catching VTK errors

[Mark Wyszomierski]

Hi Mathieu,

That's what I'd like to do, I just am not sure how to trap errors. For
instance, I'm using vtkDICOMImageReader. The reading of the files
occurs when I call Update(). But that call returns void, yet that's
where the error occurs and the vtkOutput window pops up at that
moment. I'd like to do something like:

     try {
         pMyDicomReader->Update(); // read all the files
     }
     catch (vtkDICOMImageReaderError& err)
     {
          MessageBox(err); // whatever the error is
     }

Right now I don't seem to have any way to trap simple errors like no
DICOM images in the directory etc.

Thanks,
Mark
