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) """scale参数.
