GDK might be an alternative choice when using GTK+.

And gdk_screen_*_monitor* could be a candidate of a design guide for
such a new group of functions.

  gint   gdk_screen_get_n_monitors           (GdkScreen *screen);
  gint   gdk_screen_get_primary_monitor      (GdkScreen *screen);
  void   gdk_screen_get_monitor_geometry     (GdkScreen *screen,
                                              gint monitor_num,
                                              GdkRectangle *dest);
  void   gdk_screen_get_monitor_workarea     (GdkScreen *screen,
                                              gint monitor_num,
                                              GdkRectangle *dest);
  gint   gdk_screen_get_monitor_at_point     (GdkScreen *screen,
                                              gint x,
                                              gint y);
  gint   gdk_screen_get_monitor_at_window    (GdkScreen *screen,
                                              GdkWindow *window);

                                              gint monitor_num);
