[vtkusers] How to change the behaviour of the vtkContourWidget class...??

[Shashwath T.R.]

Hi,

As of now, this is only possible by sub-classing vtkContourWidget and
reimplementing the actions you want (in other words, it's probably more
trouble than it's worth).

We've done the sub-classing, but it's really painful.

Regards,
Shash
