Scale 尺度

import tkinter as tk

window = tk.Tk()
window.title("daxiangcai's title")
window.geometry('800x400')


def printselection(v):  # scale会自动传入参数
    l.config(text='you have selected ' + v)


l = tk.Label(window, bg='green', width=20)
l.pack()

s = tk.Scale(window, label='first scale', from_=1, to=10, orient=tk.HORIZONTAL, length=200, showvalue=0,
             tickinterval=2, resolution=0.01, command=printselection)
# 这里的length以像素为单位，showvalue代表是否在滑块上面显示值，tickinterval代表显示的单位长度，resolution代表保留的小数位数
s.pack()

window.mainloop()
