[vtkusers] Method to expose events

[masabumi ishihara]

Hi VTK Users,

Now, we are tring to use wxVTK to render wxWidget images on VTK.
Then, we have a problem that we can't get the events from mouse on
wxWidget side.
Could you tell us the metod which can expose the events to wxWidget side.
If couldn't, please let us know the other way to solve the problem.

Thanks,

Maty
