我想用gtk3在框架上显示水平和垂直标尺。
我想像这样在框架上显示标尺:
但是GtkRuler已从 GTK 3 中删除,因为它没有维护且过于专业!!
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);
您对如何解决此任务有什么建议?或者我可以在互联网上的哪些资源上找到帮助?
