[vtk-developers] vtkFileOutputWindow syntax

[David Doria]

The documentation for this class says:
http://www.vtk.org/doc/nightly/html/classvtkFileOutputWindow.html#details

"To use this class, instantiate it and then call SetInstance(this)."

It seems like you have to do this:

  vtkSmartPointer<vtkFileOutputWindow> fileOutputWindow =
      vtkSmartPointer<vtkFileOutputWindow>::New();
  fileOutputWindow->SetFileName( "output2.txt" );
  fileOutputWindow->SetInstance( fileOutputWindow );

If you are supposed to call SetInstance(this), why not just set that
internally and not require a SetInstance call at all?
