[vtkusers] vtkVolumeRayCastMapper events

[Alberto García Consuegra]

Hi all, i have problems with vtkVolumeRayCastMapper events.

I see vtkVolumeRay... can listen StartEvents, EndEvent and ProgressEvent
(and they works fine), but there are others events like: *
VolumeMapperRenderProgressEvent*,
*VolumeMapperComputeGradientsEndEvent,
**VolumeMapperComputeGradientsProgressEvent
and **VolumeMapperComputeGradientsStartEvent, that i wish to listen too, but
when I add and observer to these events, nothing is being observed.

I think these events are supported in vtkVolumeMapper, and they should be
supported by vtkVolumeRayCastMapper too, because vtkVolumeRayCastMapper
inherits from vtkVolumeMapper (in my own opinion).

I use vtk 5.0.3 version in java.

Could anybody helps me?. Thanks
*
