所以我有一个窗口，其中有一个带有 3 个分区的 hbox。在第二个中，我有一个带有 2 个分区的 vbox，在这个 vbox 内我有 2 个带有他各自树视图的滚动窗口。
在我的代码中，我在第三个 hbox 分隔符中有一个 Next 按钮。单击后，我销毁了 2 个滚动窗口，并用他的 ListStore 创建了一个新的 Treeview，并对我有 2 个滚动窗口的 vbox 说 pack_start，但没有显示，只有第一个和第三个 hbox 分隔符。
这是我的代码：（我尝试在最后一个函数中创建新的 TreeView）

在最后一行之后，如果我执行“treeview_timezone.show()”之类的操作，则会显示蓝屏
谢谢
