picking and dragging actors..

[K.R.Subramanian]

I am trying to pick some actors and drag them across the screen (never
done this before
(except for point picking using the PointPicker)..

There are methods like Pickable and Dragable  in vtkProp.  I am not sure
if I need
to use these. What I had thought  of doing was to identify the actors
that were picked,
and then use the mouse functions (in vtkInteractorStyle) to identify the
current mouse
coordinates (OnMouseMove(), for instance) and use these to translate the
actors. Is this reasonable?
