I am sorry, I don't use QT. and it is Sunday afternoon here. Hopefully 
some QT user will see your thread. If you use a vtkSliderWidget in the 
scene, you could use the IteractionEvent or EndInteractionEvent 
callbacks to take the slider value and set it as the ellipse parameter.  
This would be assuming you started a vtkRenderWindowInteractor to 
interact with the vtk scene. If you calling the vtk render functions 
from your QT user interface program you would set the ellipse parameter 
values from the QT slider event calls. In both cases you would need to 
call the modified() function for your ellipse data to cause it to 
refresh the view in the renderer.

I don't think I can help you with the specific QT code.
Good luck,
Jim
