[vtkusers] Problem with 'vtkThreshold'

[Nour Mestiri]

Hi all vtk users.
I have a problem with 'vtkThreshold' class.
I want to use the output of a 'vtkThreshold ' as the input of a 'GeometryFilter'.
I do this:
vtkThreshold *thresholdEdgels = vtkThreshold::New();
...
...
vtkGeometryFilter *gf = vtkGeometryFilter::New();
gf->SetInput(thresholdEdgels->GetOutput());
 
When i this this code, i have this error:
cannot convert parameter 1 from 'class vtkUnstructuredGrid *' to 'class vtkDataObject *'
 
How should i do to rectify this?
Thanks a lot
