  651. Details:
  652. The original purpose of the STRICT_ conditionals and accessor macros was to
  653. help ease the transition to Copland.   Shared data structures are difficult
  654. to coordinate in a preemptive multitasking OS.  By hiding the fields in a
  655. WindowRecord and other data structures, we would begin the migration to 
  656. system data structures being completely hidden from applications. 
  657.  
  658. After many design reviews, it was finally concluded that with this sort of
  659. migration, the system could never tell when an application was no longer 
  660. peeking at a WindowRecord, and thus the data structure might never become 
  661. system owned.  Additionally, there were many other limitations in the classic
  662. toolbox that were begging to be addressed.
  663.  
  664. The final decision was to leave the traditional toolbox as a compatibility mode.
  665. The preferred toolbox API for Copland is a new SOM(tm) based architecture 
  666. (e.g. HIWindows.idl).  Windows, menu, controls, etc are each a SOM object 
  667. with methods for drawing, event handling, and customization.
