  18. The code should read as follow:
  19.  
  20.   Atom         wmDeleteWindow ;
  21.   Widget       shell, new_window ;
  22.   [...]
  23.   shell      = XtCreatePopupShell("mywindow", 
  24.                                   topLevelShellWidgetClass, AppShell, 
  25.                                   args, argcnt) ;
  26.   new_window = CreatemyWindow(shell) ;    /* create and manage widgets */
  27.                XtManageChild(new_window) ;
  28.                XtPopup(shell, XtGrabNone) ;
  29.  
  30.                  /* I want to handle the wm Close item. */
  31.                XtVaSetValues(shell, XmNdeleteResponse, XmDO_NOTHING, NULL);
  32.  
  33.                  /* Set up my callback for this protocol. */
  34.                wmDeleteWindow = XmInternAtom(XtDisplay(shell),
  35.                                             "WM_DELETE_WINDOW",
  36.                                             False) ;
  37.                XmRemoveWMProtocols( shell, &wmDeleteWindow, 1 );
  38.                XmAddWMProtocolCallback(shell,
  39.                                        wmDeleteWindow,
  40.                                        (XtCallbackProc)myCloseCB,  
  41.                                        (caddr_t)new_window) ;
