Hi Rupert,

I also need such a widget and have been thinking about the problem for a 
while. I think the way to go would be to write the widget as a 
vtk3DWidget. That way you can embed it in a Qt gui but you can also 
include it in any simple vtk application. I was even thinking about 
writing a Qt widget on top of the vtk widget. The Qt widget could 
include the vtk one and add or overwrite functionality to make it more 
user friendly.

If such a widget is not available in the public domain by the beginning 
of may, I will start writing one.
