[vtkusers] vtkUnstructuredGrid::InsertNextCell

[Lise Angell]

I would like to use
vtkUnstructuredGrid::InsertNextCell( int type,vtkIdType npts,vtkIdType *pts),
not vtkUnstructuredGrid::InsertNextCell( int type,vtkIdList * ptIds)


But then I get the error:
 File "readxdr.py", line 456, in mount_vtk_structures
   vtk_u_grid.InsertNextCell(vtk_cell_type, npt,  pt_list)
TypeError: function takes exactly 2 arguments (3 given)

vtk_cell_type: int, npt: int, pt_list: list of ints
Any ideas how I can reach this method (assuming it's not deprecated)?
