如何在 Tkinter（Python 3）中设置按钮宽度 [重复]

Question

我想在 python 3 中制作一个简单的测验程序，但我不知道如何让按钮达到我想要的全宽。我正在使用 python 3 和 TKinter 模块来制作窗口和所有按钮。

from tkinter import *

root = Tk()

que_labl = Label(root, text='Question')
choice1 = Button(root, text='Choice one')
choice2 = Button(root, text='Choice one plus one')
choice3 = Button(root, text='Choice 3')
choice4 = Button(root, text='Choice eight divided by 2')

que_labl.grid(row=0, columnspan=2)
choice1.grid(row=2, column=0, sticky=W)
choice2.grid(row=2, column=1, sticky=W)
choice3.grid(row=3, column=0, sticky=W)
choice4.grid(row=3, column=1, sticky=W)

root.mainloop()

代码生成一个像这样的窗口：

Answer 1

使用Grid.rowconfigure()、Grid.columnconfigure() 和sticky=E+W。

from Tkinter import *

root = Tk()
#Configure line 0 and 1
Grid.rowconfigure(root, 0, weight=1)
Grid.rowconfigure(root, 1, weight=1)

#Configure column 0 and 1
Grid.columnconfigure(root, 0, weight=1)
Grid.columnconfigure(root, 1, weight=1)

que_labl = Label(root, text='Question')
choice1 = Button(root, text='Choice one')
choice2 = Button(root, text='Choice one plus one')
choice3 = Button(root, text='Choice 3')
choice4 = Button(root, text='Choice eight divided by 2')

que_labl.grid(row=0, columnspan=2)
choice1.grid(row=2, column=0, sticky=E+W)
choice2.grid(row=2, column=1, sticky=E+W)
choice3.grid(row=3, column=0, sticky=E+W)
choice4.grid(row=3, column=1, sticky=E+W)

root.mainloop()
