[vtkusers] Using vtkSplineWidget with Qt

[Prathamesh Kulkarni]

Fellow VTK users,


I am using vtkSplineWidget to annotate different layers of an image. I
want to add more user interaction to this application by allowing the
user to delete the spline and initiate a new one for a different
layer.

Will anyone please tell me how to add this functionality without
moving on to using Qt. Is there any facility to add action buttons
using vtk?


Thanks,
Prathamesh
