获取 Checkbutton 状态 [英] Getting Checkbutton state

问题描述

如何获得 Tkinter Checkbutton 的 'state'?通过 'state' 我的意思是了解它是否有复选标记.

解决方案

当您创建它时，它需要一个 variable 关键字参数.从 Tkinter 传递一个 IntVar.选中或取消选中该框会将 var 包含的值设置为相应的布尔状态.这可以作为 var.get() 访问:

检查 => var.get()

未检查 => not var.get()

<预><代码>>>>根 = Tkinter.Tk()>>>var = Tkinter.IntVar()>>>chk = Tkinter.Checkbutton(root, text='foo', variable=var)>>>chk.pack(side=Tkinter.LEFT)>>>var.get() #unchecked0>>>var.get() #checked1

How do I get the 'state' of a Tkinter Checkbutton? By 'state' I mean get whether or not it has a check mark in it or not.

解决方案

When you're creating it, it takes a variable keyword argument. Pass it an IntVar from Tkinter. Checking or unchecking the box will set that value contained by var to the corresponding boolean state. This can be accessed as var.get():

checked => var.get()

not checked => not var.get()

>>> root = Tkinter.Tk()
>>> var = Tkinter.IntVar()
>>> chk = Tkinter.Checkbutton(root, text='foo', variable=var)
>>> chk.pack(side=Tkinter.LEFT)
>>> var.get()  #unchecked
0
>>> var.get()  #checked
1
