[vtk-developers] vtkInteractorStyleRubberBand3D::OnMouseWheelForward/Backward crashing

[Goldman, Jon]

Hi,

I checked out VTK source from the trunk today and built, and this view-based python script was crashing when I moved the mouse wheel back and forth:

  from vtk import *
  source = vtkSphereSource()
  view = vtkRenderView()
  surfaceRep = vtkSurfaceRepresentation()
  surfaceRep.SetInputConnection(source.GetOutputPort())
  view.AddRepresentation(surfaceRep)
  window = vtkRenderWindow()
  window.SetSize(600, 600)
  view.SetupRenderWindow(window)
  window.GetInteractor().Start()

It looks like this call is missing from the beginning of vtkInteractorStyleRubberBand3D::OnMouseWheelForward() and vtkInteractorStyleRubberBand3D::OnMouseWheelBackward() methods:

    this->FindPokedRenderer(
    this->Interactor->GetEventPosition()[0],
    this->Interactor->GetEventPosition()[1]);
