[vtkusers] Question regarding vtkLineWidget

[Gheorghe Postelnicu]

Hi,

I am building an application where the user will select a number of
lines and then extract data from underlying datasets.

One important thing in this project is the orientation of the line,
meaning the order in which points are extracted. One natural way to do
this seemed to be to color the two endpoints of the linewidget
differently.

As far as I could tell though, the two handles of a line widget seem
to be sharing only one property.

What is the best way to solve this?

Thanks,
