Try this:

    #OutlineFilter
    vtkUnstructuredGridReader reader$filename
        reader$filename SetFileName $filename
    vtkOutlineFilter outline$filename  
       outline$filename SetInput [reader$filename GetOutput]
    vtkPolyDataMapper outlineMapper$filename  
       outlineMapper$filename SetInput [outline$filename GetOutput]
    vtkActor outlineActor$filename  
       outlineActor$filename SetMapper outlineMapper$filename
       [outlineActor$filename GetProperty] SetColor 1 1 1
