[vtkusers] edit line nodes

[Jonathan Ruiz Peinado]

Thanks, I've followed that links and now I got something but not exactly
what I need.

The problem is that I'm not getting all point Ids in the scene, sure I'm
using something wrongly, this is what I'm doing:

I'm using vtkImagePlaneWidget to show an slice of a dicom image, and in the
same render I'm drawing some lines , poligons, etc...

I'm setting the picker for the vtkImagePlaneWidget like this:

vtkImagePlaneWidget.SetPicker(vtkPointPicker);

also I'm using the same pointPicker for the render iterator and this is how
I'm setting it up:

vtkPanel.getIren().SetPicker(vtkPointPicker);

I'm using the same point picker for both, dont know if it is right or not.

Well the problem is that I'm able to get the Ids of the planeWidget corner
points but I can't get the point Ids of the scene actors.

Do I need to set the picker somewhere else?

Set the picker just for the render iterator didn't make any difference

Thanks!
