[vtkusers] vtkSeedWidget: Recommended use?

[Benjamin Smith]

Hi all,

I'm working on an application with 3 separate slice views (using
separate render windows). I want the user to be able to add seeds in
any view, and the vtkSeedWidget seems to be the appropriate tool.  My
question: How should I make the seeds appear in each slice, and be
edited through the widget? I've cobbled together a solution by
deriving a new widget from the original, and exposing some of the
internal information, but it seems like there should be an easier way
to work with widgets and different renderers?

Thanks!

Ben
