[vtkusers] How to use vtkLineWidget2

[Jothy]

Hi all,

Has anyone used vtkLineWidget2 with vtkImageViewer2 before?  I am having
problem in interacting with it and It does not show line between two end
points.

here is my code

LineA=vtk.vtkLineWidget2()
LineA.CreateDefaultRepresentation()
LineA.SetInteractor(self.frameA.GetRenderWindow().GetInteractor())
LineA.On()

And there is no example on the wiki.

Probably if someone helps me to fix this, I will add one.

Thanks,

Jothy
