  2. //                        SAMPLE CODE
  3. //
  4. // FileName: ACDFVw2.hpp
  5. //
  6. // ClassName: ACompDocFwkView
  7. //
  8. // Description: Compound Document Framework (SimpleServer) View
  9. //              This sample is to illustrates the use of notification and the use of
  10. //              keyboard, mouse and command handlers in the server application. When 
  11. //              a notification is recieved from the model, if the handleNotification method
  12. //              was NOT overridden the drawContents would have been called and the notification ID
  13. //              not checked. 
  14. //              In this case the handleNotification method was overridden as a result different data
  15. //              is set depending on the NotificationId
  16. //              The view contains 2 entry fields to allow the user to change the model data
  17. //              by entering the new data and hitting either newline or enter. Using the keyboard
  18. //              handler to trap these events.
  19. //              Doubleclick on either of the entry fields to change the string in MyObject 
  20. //              in the model, using the mouse handler trap this event.
  21. //              The pushbutton and the menu option perform the same function which is
  22. //              to update both the strings in the model.
