我已经尝试this,但它没有帮助。
我正在制作计算器程序。到目前为止,我已经做到了这一点:
from tkinter import *
window = Tk()
disp = Entry(window, state='readonly', readonlybackground="white")
disp.grid(column=0, row=0, columnspan=4)
#row 1
seven = Button(window, text="7", command=Seven)
seven.grid(column=1,row=1)
eight = Button(window, text="8", command=Eight)
eight.grid(column=2,row=1)
nine = Button(window, text="9", command=Nine)
nine.grid(column=3,row=1)
divide = Button(window, text="÷", command=Divide)
divide.grid(column=4,row=1)
#row 2
four = Button(window, text="4", command=Four)
four.grid(column=1,row=2)
five = Button(window, text="5", command=Five)
five.grid(column=2,row=2)
six = Button(window, text="6", command=Six)
six.grid(column=3,row=2)
multiply = Button(window, text="×", command=Multiply)
multiply.grid(column=4,row=2)
#row 3
one = Button(window, text="1", command=One)
one.grid(column=1,row=3)
two = Button(window, text="2", command=Two)
two.grid(column=2,row=3)
three = Button(window, text="3", command=Three)
three.grid(column=3,row=3)
minus = Button(window, text="-", command=Minus)
minus.grid(column=4,row=3)
#row 4
zero = Button(window, text="0", command=Zero)
zero.grid(column=1,row=4)
dec = Button(window, text=".", command=Dec)
dec.grid(column=2,row=4)
equal = Button(window, text="=", command=Equal)
equal.grid(column=3,row=4)
add = Button(window, text="+", command=Add)
add.grid(column=4,row=4)
window.mainloop()
这看起来像这样(我的声望太低,无法发布图片):https://i.imgsafe.org/268d2a57c1.jpg (编辑:图片链接折旧)
我希望盒子同样宽,并填满可用空间。 结果应类似于:http://python.6.x6.nabble.com/file/n4545517/skaiciavke.png
如何使按钮占据行/列的整个宽度?
答案 0 :(得分:6)
两件事:
.grid
按钮时,请使用sticky=N+S+E+W
。这将允许按钮按其各自的行和列大小进行扩展。更新:
N + S + E + W不适用于python3.6.7,它是nesw
或这4个字母的任意组合。
例如:
#!/usr/bin/python
# -*- coding: utf-8 -*-
from tkinter import *
window = Tk()
disp = Entry(window, state='readonly', readonlybackground="white")
disp.grid(column=0, row=0, columnspan=4)
#row 1
seven = Button(window, text="7")
seven.grid(column=0,row=1, sticky='nesw')
eight = Button(window, text="8")
eight.grid(column=1,row=1, sticky='nesw')
nine = Button(window, text="9")
nine.grid(column=2,row=1, sticky='nesw')
divide = Button(window, text="÷")
divide.grid(column=3,row=1, sticky='nesw')
window.mainloop()
返回一个如下所示的窗口:
