Sounds as if you're wanting the same callback to be called twice for a
single event, I don't think that GTK+ will do that.  Whatever the
functionality of your callback, it should be trivial to write it so that
it updates both drawing area widgets.  Either way, this is a GTK+
question, not releated to GtkGLExt.
