Tkinter之Radiobutton

提供用户选项时会用到，一次只能选择其中一个，不能多选。

 

示例：

import Tkinter as tk 

window = tk.Tk()

window.title('My Window')

window.geometry('500x300')  

 

 

def print1():

    print ("你的选择是："+v.get())   

 

v = tk.StringVar()

v.set('ss')    # 设置默认选中的按钮

 

#当鼠标选中了某个选项，会把value的值放到变量v中，v再赋值给variable

l1 = tk.Radiobutton(window, text='aaa', variable=v, value='aaa',command=print1)

l1.pack(anchor='w')

l2 = tk.Radiobutton(window, text='ss', variable=v, value='ss',command=print1)

l2.pack(anchor='w')

l3 = tk.Radiobutton(window, text='d', variable=v, value='d',command=print1)

l3.pack(anchor='w')

 

    

window.mainloop()

 

 

 

比较实用的代码示例：

import Tkinter as tk 

window = tk.Tk()

window.title('My Window')

window.geometry('500x300')  

 

 

def print1():

    print ("你的选择是："+selectons[v.get()-1][0])

 

selectons=[('python',1),('C++',2),('C',3)]

 

v = tk.IntVar()

v.set(3) 

 

for i,j in selectons:

    l = tk.Radiobutton(window, text=i, variable=v, value=j,command=print1)

    l.pack(anchor='w')

    

    

window.mainloop()
