对齐 Tkinter 单选按钮

Question

我的 Tkinter 单选按钮未对齐。我试过这个Python tkinter align radio buttons west, this Python tkinter align radio buttons west，其中none有效，我看到的是这个

当我使用网格来管理小部件时（必须是网格，因为它是更大 UI 的一部分）。

我已经尝试过锚点和证明，但得到的回溯表明这些是不允许的：

代码

import tkinter as tk

root = tk.Tk()

value = tk.IntVar()
value.set(0)  # initializing the choice, i.e. mrads


def get_traj_method():
    print(value.get())

tk.Label(root, text="""T method:""", justify = tk.LEFT, padx = 20).grid(row=0)

tk.Radiobutton(root, text='T_Deviation', padx = 20, variable=value, command=get_traj_method, value=0).grid(row=1, sticky=tk.E)
tk.Radiobutton(root, text='T_Degrees', padx = 20, variable=value, command=get_traj_method, value=1).grid(row=2, sticky=tk.E)

root.mainloop()

Answer 1

将 sticky = "W" 代替 tk.E（tk.W 应该也可以）

小部件有不同的大小，所以当它们向东（右）锁定时，两端对齐，但开头（在本例中为按钮）不会对齐。

当把sticky = "W" 的时候，情况正好相反。 :

import tkinter as tk

root = tk.Tk()

value = tk.IntVar()
value.set(0)  # initializing the choice, i.e. mrads


def get_traj_method():
    print(value.get())

tk.Label(root, text="T method:", justify = tk.LEFT).grid(row=0)

tk.Radiobutton(root, text='T_Deviation', variable=value, command=get_traj_method, value=0).grid(row=1, sticky="W")
tk.Radiobutton(root, text='T_Degrees', variable=value, command=get_traj_method, value=1).grid(row=2, sticky="W")

root.mainloop()
