无法让滚动条工作 PyGTK 树视图

Question

首先，我首先要说的是，我在这里阅读了很多内容，并且我已经在谷歌上搜索了答案，但一直无法找到答案。

基本上我正在尝试添加一个滚动条以添加到我的 vbox 窗口。我知道这只是我不理解的事情。这是代码（请忽略 mysql 语句，我还没有时间清理它们，

您将在其中看到以下内容：

# For some reason I can't get the scrolled window to work...
self.scrolledwindow = gtk.ScrolledWindow()
self.scrolledwindow.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)

当我尝试通过我附加它

self.scrolledwindow.add_with_viewport(self.treeview)

时，我收到消息

GtkWarning: Attempting to add a widget with type GtkTreeView to a container of type GtkFrame, but the widget is already inside a container of type GtkViewport

我去了常见问题解答页面，但我我真的不明白它在告诉我什么。

如果我尝试在 self.window 上设置，我会得到：

GtkWarning: Can't set a parent on a toplevel widget
self.scrolledwindow.add_with_viewport(self.window)

那是非常不言自明的。

如果我尝试将它添加到 vbox ， 代码> 我明白：

GtkWarning: IA__gtk_scrolled_window_add_with_viewport: assertion `child->parent == NULL' failed[/quote]

我不是在寻找免费赠品但我希望有人能帮助我指出正确的方向（正如你所看到的，我没有提供“你能为我制作一个执行 X 功能的程序吗？”的场景）

我仍然遇到与滚动条相同的问题，我怀疑这是我向容器添加小部件的方式

注意：我从第一个删除了 mysql 语句 。 GUI 节省帖子空间

Answer 1

与我的工作代码的唯一区别是我不使用“add_with_viewport”：

    swH = gtk.ScrolledWindow()
    swH.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)
    swH.add(treeviewH)

它工作正常。请尝试一下，然后告诉我是否可以。如果没有，我会进一步挖掘。
