是否有替代＆＃34; GtkRuler＆＃34;在GTK3？

Question

我想用gtk3在框架上显示水平和垂直标尺。

这是我的框架：

我想在框架上显示标尺：

但 GtkRuler 已从GTK 3中移除，因为它没有维护且太专业!!

这是我的GTK3 / c cpde：

   /* The horizontal ruler goes on top. As the mouse moves across the
    * drawing area, a motion_notify_event is passed to the
    * appropriate event handler for the ruler. */
   hrule = gtk_hruler_new ();
   gtk_ruler_set_metric (GTK_RULER (hrule), GTK_PIXELS);
   gtk_ruler_set_range (GTK_RULER (hrule), 7, 13, 0, 20);
   g_signal_connect_swapped (area, "motion_notify_event",
                      G_CALLBACK (EVENT_METHOD (hrule,        motion_notify_event)),
                      hrule);
   gtk_table_attach (GTK_TABLE (table), hrule, 1, 2, 0, 1,
              GTK_EXPAND|GTK_SHRINK|GTK_FILL, GTK_FILL, 0, 0);

   /* The vertical ruler goes on the left. As the mouse moves across
    * the drawing area, a motion_notify_event is passed to the
    * appropriate event handler for the ruler. */
   vrule = gtk_vruler_new ();
   gtk_ruler_set_metric (GTK_RULER (vrule), GTK_PIXELS);
   gtk_ruler_set_range (GTK_RULER (vrule), 0, YSIZE, 10, YSIZE );
   g_signal_connect_swapped (area, "motion_notify_event",
                      G_CALLBACK (EVENT_METHOD (vrule, motion_notify_event)),
                      vrule);
   gtk_table_attach (GTK_TABLE (table), vrule, 0, 1, 1, 2,
              GTK_FILL, GTK_EXPAND|GTK_SHRINK|GTK_FILL, 0, 0);

您建议如何解决此任务的想法？或者我可以在互联网上的哪些资源上找到帮助？

如果您的代码具有兼容的许可证，您只需将GtkRuler从GTK 2复制到您的代码中，进行必要的更改以使其与GTK 3一起使用。
