我正在使用gridTkinter 的几何管理器在第 2 列中生成一个带有水平滚动文本的表格。我尝试创建一个Listbox位于第 2 列（作为整个框架的子项）并跨越所有行的小部件。这似乎很有希望，直到 Listbox 中的文本行明显与父网格的行不对齐。我一直在徒劳地寻找一种方法来填充列表框中的每一行文本以使行匹配；但即使这是可能的，我更喜欢更通用、不那么笨拙的解决方案。
我最近偶然发现了对 Gridded Geometry Management 的描述，它暗示了一个小部件的 setgrid 选项。它声称完全符合我的要求：即“[确定]此小部件是否控制其顶级窗口的大小调整网格。” 我尝试在我的Listbox小部件中启用此选项，但无济于事。我是否以某种方式误解了 setgrid 的目的/用法？
（为了查看下面代码的问题，请使用Select File或Select Folder按钮将多个音频文件加载到文件列表中。）
