[vtkusers] how to pick vtkActor2D?

[永强 谭]

Hi, vidyadhar,

Thank you for your suggestion and it works after I change vtkCellPicker to 
vtkPropPicker.
Now comes another question. The vtkPropPicker seams to work in an acurate 
way. When the vtkActor2D object that I want to pick is just a thin line, I 
find it is not easy to pick. Is there any way to work around this?

yours,
