You're not passing it to itself, you're calling a *static* method to set a
static data member with an instance pointer.

It would be better phrased as:

  vtkOutputWindow::SetInstance(fileOutputWindow);

rather than:

  fileOutputWindow->SetInstance(fileOutputWindow);

because the "class::static_method" phrasing reflects what's actually
happening.
