Tkinter 之Scale滑块标签

一、参数说明

语法	作用
Scale(window, label="滑块"）	滑块标题
Scale(window, label="滑块", from_=0）	滑块最小值为0
Scale(window, label="滑块", to=100）	滑块最大值为100
Scale(window, label="滑块", length=200）	滑块长度为200
Scale(window, label="滑块", orient = tk.HORIZONTAL）	滑块水平方向显示
Scale(window, label="滑块", resolution=0.01）	滑块值的精度为0.01
Scale(window, label="滑块", digits = 8）	设置显示的位数为8
Scale(window, label="滑块", command=select）	滑动时的回调
scale.get()	获取当前滑块位置的值
scale.set(10)	设置滑块的值

二、代码示例

import tkinter as tk

window = tk.Tk()
# 设置窗口大小
winWidth = 600
winHeight = 400
# 获取屏幕分辨率
screenWidth = window.winfo_screenwidth()
screenHeight = window.winfo_screenheight()

x = int((screenWidth - winWidth) / 2)
y = int((screenHeight - winHeight) / 2)

# 设置主窗口标题
window.title("Scale参数说明")
# 设置窗口初始位置在屏幕居中
window.geometry("%sx%s+%s+%s" % (winWidth, winHeight, x, y))
# 设置窗口图标
window.iconbitmap("./image/icon.ico")
# 设置窗口宽高固定
window.resizable(0, 0)
