[vtkusers] Problem with select slice of ImageSliceViewer

[Renaud Isabelle]

Hi,
 
I have a problem while calling  SelectSlice() of ImageSliceViewer class.
 
When launching my application, this method is called a first time and I can see the first slice of my volume in the window. 
 
However, when I call this method again, it is always the same slice that is displayed. No change has occured. Why? All I have to do is calling Render() method after having selected a slice, and not execute the pipeline another time, right?
 
Here is how I call it:
 
- ImageSliceViewer.SelectSlice(slice);
- ImageSliceViewer.Render();
 
void vtkSliceViewer::SelectSlice( int slice )
{
  int MinMaxSlice[6];
  m_Actor->GetInput()->GetExtent( MinMaxSlice );
  if ((slice>=MinMaxSlice[4]) && (slice<=MinMaxSlice[5]))
         MinMaxSlice[4] = MinMaxSlice[5] = slice;
  m_Actor->SetDisplayExtent(MinMaxSlice);
}

Could someone help me please....

Isabelle
