   Does anyone know how to make use of the OPENWIN_VERTICAL_SCROLLBAR attribute
   using xv_get inside of a canvas repaint proc?  I want to get hold of the
   scrollbar associated with the current canvas being repainted.  The problem
   is that I can't seem to find the proper arguement for the xv_get() so
   that the scrollbar is returned.  The O'Reilly book (and the OpenWINDOWS 1.0B)
   are very Xv_Opaque about how to accomplish this.


Because a canvas is a subclass of Openwin, you can simply do a

scrollbar = (Scrollbar) xv_get(canvas, OPENWIN_VERTICAL_SCROLLBAR, 0);

Hope this helps,
