[Paraview] progress from internal filter

[Biddiscombe, John A.]

Can anyone point me to a filter in paraview (or plain VTK for that matter) that correctly updates its progress based on the progress of an internal filter. I'd like to cut'n'paste how it's done to save myself time doing it from scratch.

thanks

JB
