Here is some sample code that works for me:

     #include <gtk/gtk.h>
     #include <stdio.h>

     void
     log_func (const gchar    *log_domain,
               GLogLevelFlags  log_level,
               const gchar    *message,
               gpointer        user_data)
     {
       printf("HA-HA-HA\n");
     }


     int
     main (int argc, char **argv)
     {
       gtk_init (&argc, &argv);

       /* Use G_LOG_LEVEL_MASK to get all log levels, instead of just
        * CRITICAL/WARNING. 
        */
       g_log_set_handler ("Gtk",
                          G_LOG_LEVEL_CRITICAL | G_LOG_LEVEL_WARNING |
                          G_LOG_FLAG_FATAL | G_LOG_FLAG_RECURSION,
                          log_func, NULL);

       gtk_widget_show (NULL);

       return 0;
     }

I apologize for this API, it's sort of strange IMO. It's documented
here:

  http://developer.gnome.org/doc/API/2.0/glib/glib-message-logging.html

You may want to set a handler for the "Gdk" domain as well as "Gtk".

BTW, I've noticed some code that appears to stuff pointers into the
Java "int" type - isn't this going to blow up on 64-bit platforms?
Or am I misunderstanding the code?
