我想做一个简单的计算器,并且我希望在我的按钮上有一个条目小部件,但网格不工作。Tkinter条目和网格
这是我的代码:
from tkinter import *
w = 6
h = w - 3
root = Tk()
root.title("Calculator")
def callback():
print("pressed")
e = Entry(root)
e.grid(row=1, column=1)
b1 = Button(root, bg='white', width=w, height=h, text="1", activebackground="black", activeforeground="white", command=callback)
b1.grid(row=2, column=1)
b2 = Button(root, bg='white', width=w, height=h, text="2", activebackground="black", activeforeground="white", command=callback)
b2.grid(row=2, column=2)
b3 = Button(root, bg='white', width=w, height=h, text="3", activebackground="black", activeforeground="white", command=callback)
b3.grid(row=2, column=3)
b4 = Button(root, bg='white', width=w, height=h, text="4", activebackground="black", activeforeground="white", command=callback)
b4.grid(row=3, column=1)
b5 = Button(root, bg='white', width=w, height=h, text="5", activebackground="black", activeforeground="white", command=callback)
b5.grid(row=3, column=2)
b6 = Button(root, bg='white', width=w, height=h, text="6", activebackground="black", activeforeground="white", command=callback)
b6.grid(row=3, column=3)
b7 = Button(root, bg='white', width=w, height=h, text="7", activebackground="black", activeforeground="white", command=callback)
b7.grid(row=4, column=1)
b8 = Button(root, bg='white', width=w, height=h, text="8", activebackground="black", activeforeground="white", command=callback)
b8.grid(row=4, column=2)
b9 = Button(root, bg='white', width=w, height=h, text="9", activebackground="black", activeforeground="white", command=callback)
b9.grid(row=4, column=3)
b0 = Button(root, bg='white', width=w, height=h, text="0", activebackground="black", activeforeground="white", command=callback)
b0.grid(row=5, column=2)
AC = Button(root, bg='white', width=w, height=h, text="AC", activebackground="black", activeforeground="white", command=callback)
AC.grid(row=5, column=1)
plus = Button(root, bg='white', width=w, height=h, text="+", activebackground="black", activeforeground="white", command=callback)
plus.grid(row=2, column=4)
minus = Button(root, bg='white', width=w, height=h, text="-", activebackground="black", activeforeground="white", command=callback)
minus.grid(row=3, column=4)
mult = Button(root, bg='white', width=w, height=h, text="×", activebackground="black", activeforeground="white", command=callback)
mult.grid(row=4, column=4)
div = Button(root, bg='white', width=w, height=h, text="÷", activebackground="black", activeforeground="white", command=callback)
div.grid(row=5, column=4)
equ = Button(root, bg='white', width=w, height=h, text="=", activebackground="black", activeforeground="white", command=callback)
equ.grid(row=5, column=3)
root.mainloop()
这是我的输出: Output
如何使程序的按钮排队与输入框,同时还采用网格管理器?
尝试进行以下更改并让我知道您是否希望如此。 'e = Entry(root,width = w * 6); 实例(行= 1,列= 1,列距= 4)' – Reti43
看看计算器的例子[这里](http://zetcode.com/gui/tkinter/layout/)。它似乎是做你想做的。 –
谢谢你们解决了我的问题!节日快乐,并有一个很好的编程年! –
