如何将Entry Widget填充到LabelFrame的末尾？

Question

如何根据LabelFrame的宽度自动将Entry Widget填充到最后一个

Answer 1

您需要的是columnconfigure()和sticky='ew'的组合。我看到您正在设置框架的高度和宽度，并通过禁用网格传播来强制它，但是我不是100％确定需要这样做。

看下面的例子。

不带grid_propagate(0)的示例：

import tkinter as tk


root = tk.Tk()
root.geometry('250x200')
root.columnconfigure(0, weight=1)  # Used to allow column 0 in root to expand

some_frame = tk.LabelFrame(root, text='Hello')
some_frame.grid(row=0, column=0, sticky='ew')
some_frame.columnconfigure(1, weight=1)  # Used to allow column 1 in some_frame to expand

entry = tk.Entry(some_frame)
entry.grid(row=0, column=1, sticky='ew')

root.mainloop()

grid_propagate(0)的示例：

import tkinter as tk


root = tk.Tk()

some_frame = tk.LabelFrame(root, text='Hello', width=250, height=200)
some_frame.grid(row=0, column=0)
some_frame.grid_propagate(0)  # Not sure why you are doing this You can have the frame expand with the window as well
some_frame.columnconfigure(1, weight=1)  # Used to allow column 1 in some_frame to expand
entry = tk.Entry(some_frame)
entry.grid(row=0, column=1, sticky='ew')

root.mainloop()
