python GUI编程之Tkinter详解合集一种简单的布局方法，如果不加参数的默认方式，将按布局语句的先后，以最小占用空间的方式自上而下地排列控件实例，并且保持控件本身的最小尺寸。0 是最左边，0.5 是正中间，1是最右边；“n”, “s”, “w”, “e”, “nw”, “sw”, “se”,“ne”, “center”(默认)“n”, “s”, “w”, “e”,“nw”, “sw”, “se”,“ne”, “center”(默认)“n”, “s”, “w”, “e”,“nw”, “sw”, “se”,“ne”, “center”(默认) 阅读详情

Checkbutton

import tkinter as tk

window = tk.Tk()
window.title("CheckButton")
window.geometry('300x200')

label = tk.Label(window,bg='yellow',width=20,height=2)
label.pack()
def print_selection():
    if var1.get() == 1 and var2.get() == 0:
        label.config(text='I only love Python!')
    elif var1.get() == 0 and var2.get() == 1:
        label.config(text='I only love C++')
    elif var1.get() == 1 and var2.get() == 1:
        label.config(text='I love both')
    else:
        label.config(text="I don't love either")

var1 = tk.IntVar()
var2 = tk.IntVar()
cb1 = tk.Checkbutton(window,text='Python',variable=var1,onvalue=1,offvalue=0,command=print_selection)
cb2 = tk.Checkbutton(window,text='C++',variable=var2,onvalue=1,offvalue=0,command=print_selection)
