[vtkusers] VTK Volume Rendering and Animation in Qt slots

[lijiafan]

Hi.
I'm a newbie to vtk. I'm currenty working on a small program which does
voluming rendering and animation in a qt window. The problem is, both
functions worked well with normal function calls, but when they were called
in qt slots nothing was drawn on the QVTKWidget2.  Also whether called in qt
slots or by normal functions all the other qt widgets stopped responding
when the animation scene was playing.
My code was forked from VTK's example code  AnimateActors
<http://www.vtk.org/Wiki/VTK/Examples/Cxx/Animation/AnimateActors>  . Is
there something i missed or not properly used? 

Thanks,
lijiafan
