[vtkusers] Information during callback / vtkImplicitPlaneWidget2

[Sebastian Gatzka]

Or can I talk to the textActor like this?

     vtkTextActor *ta = reinterpret_cast<vtkTextActor*>(caller);
     ta->SetInput("TEST");

or like this?

    this->TextActor->SetInput("TEST");

No, does not work either way.
