[vtkusers] Does anybody know how to use vtkIdType in Python?

[Youbing Zhao]

Thank you very much, yes I made a mistake on the argument type.  The problem
has been solved now :)

The code looks like the following

    num = model.GetNumberOfPoints()
    ids = vtk.vtkIdList()
    ids.SetNumberOfIds(num);
    model.Allocate(1,1)

    for i in range(0, num):
        ids.SetId(i, i)
        model.InsertNextCell(vtk.VTK_VERTEX, ids)
