[vtkusers] edit line nodes

Mon Jul 23 07:12:54 EDT 2012

Hi, I'm drawing some shapes in a render, so far so good, but I need to edit
this shapes aswell,  and is at this point where I get lost. I don't know
how to get the shape or point from the render using mouseclick event, I
know that I can get actors using vtkpicker but not sure if it can help me
or how should I go from there.

Any advise?

Thanks.
