[vtkusers] vtkPlaybackWidget not working in Activiz.NET

[David Cole]

In ActiViz .NET, you cannot derive a new class from a VTK wrapper
class. You would have to write the class in C++ and then wrap it to
generate the class on the managed/.NET side.

You can intercept events fired from the VTK objects: there should be
decent examples of how to do that in ActiViz .NET, but no deriving
classes in the wrapper layer without having a corresponding class on
the unwrapped side.


Hope this helps,
David C.
