Hey guys and ladies!

I have a polydata and use a vtkInteractionStyleTrackBallCamera to move
around. In a Special mode i can insert a plane and now i want wo make this
plane movable but only in one Dimension (normal of the plane). 

I made a subclass of vtkinteractionstyletrackballcamera and react on the
mousedown and mouseup Events. There i Color the plane so if you click on it
the plane change to red. What is the typical "vtk" way to move this plane?

- own interaction style where i parse the mousemoving into world space to
know the direction i have to move the plane?
- use normal interactionstyle "trackballcamera" and Change the style to
"trackballactor" after clicking the plane and Change back at the end? 
- use a widget? (i still have the Problem with the "placewidget()" method,
which wants a intptr instead of double[] for bounds in c#.

is there any example of moving one object by drag and drop in a world you
normally use vtkinteractorstyletrackballcamera?
