[vtkusers] WarningDisplay

[Mark Wyszomierski]

I haven't looked at it in awhile, but I think you can create an
error/warning observer on the class you're using that generates the
messages. When an error or warning occurs, your observer has a chance
to intercept it and you can do whatever you want with it (ie. write it
to disk in a log file). There may be other examples on how to use this
out there, in general you do something like:

    pTheVtkInstance->AddObserver(vtkCommand::ErrorEvent,   yourObserver);

There may be a global method for doing this, but I don't know another
way to do it.

If it helps, I put an example of how to do this observer method here:

though as mentioned before, perhaps there is a better way.
