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)
