一、參數說明
| 語法 | 作用 |
|---|---|
| Scale(window, label="滑塊"） | 滑塊標題 |
| Scale(window, label="滑塊", from_=0） | 滑塊最小值為0 |
| Scale(window, label="滑塊", to=100） | 滑塊最大值為100 |
| Scale(window, label="滑塊", length=200） | 滑塊長度為200 |
| Scale(window, label="滑塊", orient = tk.HORIZONTAL） | 滑塊水平方向顯示 |
| Scale(window, label="滑塊", resolution=0.01） | 滑塊值的精度為0.01 |
| Scale(window, label="滑塊", digits = 8） | 設置顯示的位數為8 |
| Scale(window, label="滑塊", command=select） | 滑動時的回調 |
| scale.get() | 獲取當前滑塊位置的值 |
| scale.set(10) | 設置滑塊的值 |
二、代碼示例
import tkinter as tk
window = tk.Tk()
# 設置窗口大小
winWidth = 600
winHeight = 400
# 獲取屏幕分辨率
screenWidth = window.winfo_screenwidth()
screenHeight = window.winfo_screenheight()
x = int((screenWidth - winWidth) / 2)
y = int((screenHeight - winHeight) / 2)
# 設置主窗口標題
window.title("Scale參數說明")
# 設置窗口初始位置在屏幕居中
window.geometry("%sx%s+%s+%s" % (winWidth, winHeight, x, y))
# 設置窗口圖標
window.iconbitmap("./image/icon.ico")
# 設置窗口寬高固定
window.resizable(0, 0)
