[vtkusers] how to pick vtkActor2D?

[vidyadhar]

Hi,
Unlike the vtkCellPicker, vtkPropPicker does not have a SetTolarance method.
This is a problem which I am also facing. So far I could not find a work
around. I have problems because I have some other widgets also in my seen.
Because of lack of tolarance, the picker seems to always pick this one
object and other objects/widgets are not able to get the pick. Maybe
somebody else on the mailing list could give us some ideas.

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,
