  19. That's correct.  You could even pass fMyObjectOfInterest as a parameter to
  20. your extension's InitMySOMNautilusShellExtension method.
  21.  
  22. (By the way, when I copy/pasted my extension code, I forgot to rename that
  23. method.  You would almost certainly call it something like
  24. InitXYZExtension).
  25.  
  26. You must remember that by storing a C++ object pointer in your extension
  27. you are responsible for keeping the extension and part built with the same
  28. version of the same sources with the same compiler (since C++ object
  29. layouts differ among compilers/compiler versions).  On a related note, an
  30. extension should *never* reveal the C++ object to its clients.  They
  31. wouldn't know what to do with it :-)
