以下MWE用于具有水平和垂直滚动条的窗口 . 该窗口包含一个输入框，其中显示当前工作目录 . 但是，输入框中的文字不能全部被视为框太小 . 我希望能够在用户放大窗口时显示更多此文本 . 如何调整以下示例，以便使用窗口调整Entry框(在UserFileInput中定义)的大小？我尝试过使用 window.grid_columnconfigure (见下文)，但这没有任何效果 . 这似乎是使用画布的一个问题，因为之前我能够让Entry框调整大小，但是我需要画布才能将水平和垂直滚动条放在窗口上 .

window.grid(row=0, column=0, sticky='ew')

window.grid_columnconfigure(0, weight=1)

(以及列= 1)但这没有效果 .
