[vtkusers] Load update of datafile

[Benitio del Cruz]

Hi All,

I'm working on a visualisation tool which receives its input through 
vtk-data files created by a simulation model.
Every now and then (period > few seconds) the next simulation step is 
computed, and saved to the -same- datafiles. I already have a little module 
which checks the file-attributes to see whether it's changed or not, but the 
problem is the actual vtk-pipeline-update: it consist of a vtkDataSetReader, 
to which several filters are attached.
No matter how I try to tickle the reader, it won't reread the file. I've 
tried Update(), OpenVTKFile(), Modified(), etc. I worked around it for the 
moment by creating a second vtkDataSetReader, pointing to the same file, 
attaching it to the pipeline, and then deleting the old one. It is kind of 
working, but not exactly a nice solution.
Anybody got any ideas?

yours sincerely,
Benitio
