  26. No, if you are adding a callback to a button directly, you can use
  27. XmNactivateCallback.  But when adding a callback to a dialog, motif dialogs
  28. support XmokCallback, XmNcancelCallback, etc.  However, if you are asking
  29. about the window manager close button on the dialog's window manager frame,
  30. that's different. For that, you need to use something like the following:
  31.  
  32.         Atom WM_DELETE_WINDOW = XInternAtom( XtDisplay(dialogshell),
  33.                         "WM_DELETE_WINDOW", 
  34.                         FALSE);
  35.  
  36.     XmAddWMProtocolCallback( dialogshell, WM_DELETE_WINDOW,
  37.                 &VkSimpleWindow::deleteWindowCallback, 
  38.                 NULL);
  39.  
  40.     XtVaSetValues( dialogshell, 
  41.               XmNdeleteResponse, XmDO_NOTHING, 
  42.               NULL);
