<DIV>For testing, i move the operation to right button menu, and just
use [actor->RotateX(30.0)]. But the result was the same, after i clicked the
rightButton menu , the render window show nothing. Besides, i tried another
test, i changed my data source to vtkConeSource , it runs Ok. My
former data source was :</DIV>

<DIV>Did you call renderWindow->Render()? You'll probably have to make
us an as-small-as-possible code sample so we can see exactly what you're
