我想让文本框在屏幕底部的大部分区域内占据空间，滚动条只在最右边的一侧呈现。但当前我的代码让文本框和滚动条在窗口中部各占一半。这是为什么？我该如何修复？

解决方案

你有这么多嵌套的 Frame，所以很难找出问题所在。

解法需要在三个地方进行修改，才能看到结果。

我尝试了多种组合，结果对我来说是可行的。

logbox_frame.columnconfigure(0, weight=1)  # <--- weight

class logbox(tk.Frame):
    def __init__(self, parent):
        super().__init__(parent)

        self.columnconfigure(0, weight=1)  # <-- weight

        # ... code ...

        self.grid(row=0, column=0, columnspan=2, sticky="news")  # <--- sticky

完整可运行的代码。

我在某些元素中添加了 background=，以便更清楚地看到哪些元素没有使用全宽。你可以把它移除。

它还需要在带有 Scrollbar 的列中使用 weight=0，以实现最小宽度。

顺便说一句：推荐把 UpperCaseNames 用于类名、lower_case_names 用于实例——例如用 class Logbox() 和 logbox = Logbox(..)，代替 class logbox() 和 Logbox = logbox(..)（这与代码中其他控件的命名风格类似）。
