ParaView queues up the changes, and only applies them to the filters 
when the apply button is pressed.
If you're applying them on the filters when spinboxes/lineedits change, 
and a menu comes and goes over the graphics view, that could trigger an 
update you might not want.

How about your apply button gathering the parameters from the widgets on 
the form and applying them?
