7.3、Scale 绑定变量

# variable:指定与 scale 绑定的变量名称
# -*- coding: cp936 -*-
from Tkinter import *
root = Tk()
v = StringVar()

Scale(root,
from_ = 0, #设置最小值
to = 100.0, #设置最大值
resolution = 0.0001, #设置步距值
orient = HORIZONTAL, #设置水平方向
variable = v #绑定变量
).pack()
print v.get()
root.mainloop()
# v 的值与 Scale 的值一致

代码

from tkinter import *
quehui = Tk()
v = StringVar()
Scale(quehui,
from_ = 0,
to = 100,
resolution = 0.001,
orient = HORIZONTAL,
variable = v,
).pack()
print(v.get())
quehui.mainloop()
