Checkbutton返回值

Question

在这段代码中，我看不到值是如何变化的，因为某些原因，它总是显示PY_VAR1。我在网上做了一点调查，我似乎找不到一个直接的答案，如何获得价值，如果它按下。在

from Tkinter import *
import tkMessageBox
import Tkinter


top = Tkinter.Tk()
CheckVar1 = IntVar()
CheckVar2 = IntVar()
def test():
    print(CheckVar2)
C1 = Checkbutton(top, text = "Music", variable = CheckVar1, \
             onvalue = 1, offvalue = 0, height=5, \
             width = 20)
C2 = Checkbutton(top, text = "Video", variable = CheckVar2, \
                  height=5, onvalue = 1, offvalue = 0,\
                 width = 20, command = test)
C1.pack()

C2.pack()
top.mainloop()

将来我需要使用if语句和everything if值是1等等

.get()将解决您的问题：）

from Tkinter import *
import tkMessageBox
import Tkinter


top = Tkinter.Tk()
CheckVar1 = IntVar()
CheckVar2 = IntVar()
def test():
    print(CheckVar2.get()) # Notice the .get()
C1 = Checkbutton(top, text = "Music", variable = CheckVar1, \
             onvalue = 1, offvalue = 0, height=5, \
             width = 20)
C2 = Checkbutton(top, text = "Video", variable = CheckVar2, \
                  height=5, onvalue = 1, offvalue = 0,\
                 width = 20, command = test)
C1.pack()

C2.pack()
top.mainloop()
