  12. //    LPPobView is a class that will load a PPob resource and put the
  13. //    superview of this hierarchy as a subview of the LPPobView's superview.
  14. //
  15. //    It is useful when you want to have a few view that are superposed as
  16. //    in preferences panels.

  20. //    Instruction Notes:
  21. //    -----------------
  22. //
  23. //    1) Write a PPob resource with Constructor (or whatever you want!) which is
  24. //       a View;
  25. //
  26. //    2) In the class you want to insert the View, insert a LPPobView;
  27. //
  28. //    3) At the beginning of your application, add the call:
  29. //
  30. //        URegistrar::RegisterClass(LPPobView::class_ID, LPPobView::CreatePPobViewStream);
  31. //
  32. //    4) In your application you can use the inserted view as if is was
  33. //       created inside the Window or the dialog in the first time.
