Thank you for the quick and useful answer.
What I define as the orientation of the plane is the orientation value of it
as it were an actor (and not a 3dWidget).
Like in the definition of vtkProp3D.GetOrientation():
"Returns the orientation of the Prop3D as s vector of X,Y and Z rotation..."

I had the same idea with "Get{Origin,Point1,Point2}()", but I hoped two find
an easier way.

But I am not sure what I have to do, when I use "planeWidget.GetNormal()".
How can I convert the information from "GetNormal" to something for
"actor.SetOrientation()".
