关键是，当我放置时ttk.Treeview .pack(expand=1, fill=BOTH)，它只会拉伸X，尽管我BOTH在父框架中的任何地方都放置了expand.

为什么不延伸Y。怎么做？

    关键是，当我放 时ttk.Treeview .pack(expand=1, fill=BOTH)，它只扩展为 X，尽管事实上我在父框架中的任何地方都放了 BOTH，就像展开一样。

    BOTH您只为具有树视图（self._w和self.filelistframe2）的容器指定。

    对树本身也必须这样做（至少对正确的树），因为 右边的树伸展到它的标准尺寸（或内容，从截图中看不清楚），但框架结果更高。

    也就是说，这里：

    self.listbox=ttk.Treeview(self.filelistframe2,columns=("1n","2n",'3n'), height=27)
...
self.listbox.pack(side=LEFT, fill = 'x', expand=1)

    需要更换fill='x'为fill=BOTH.

    对于左边的树，顺便说一下，它被指示fill='y'（仅垂直填充），但这并不明显，因为在这种情况下帧之间的边界不能移动（如果你把它放在ttk.Seprartor帧之间并尝试将它移动到右边，则左侧树的右侧会出现一个间隙）。
