我正在使用 Glade 来设计一个 GUI。当我插入 GtkEntry 字段时，我可以使用 Tab 键导航到下一个字段（此功能在 Glade 中是“免费”提供的）。但是，似乎我不能使用 Shift-Tab 来聚焦前一个选项卡条目。

当我有两个按钮时，Tab 和 Shift-Tab 都是开箱即用的。

那么：有没有办法让 Shift-Tab 聚焦 Glade 中的前一个 GtkEntry？

Glade 代码如下；一个有两个输入字段，一个有两个按钮。

两个条目：

<?xml version="1.0" encoding="UTF-8"?>
<interface>
  <!-- interface-requires gtk+ 3.0 -->
  <object class="GtkWindow" id="window1">
    <property name="can_focus">False</property>
    <child>
      <object class="GtkBox" id="box1">
        <property name="visible">True</property>
