二、代码示例

import tkinter as tk

window = tk.Tk()

def main():
    global window
    # 设置主窗体大小
    winWidth = 600
    winHeight = 400
    # 获取屏幕分辨率
    screenWidth = window.winfo_screenwidth()
    screenHeight = window.winfo_screenheight()
    # 计算主窗口在屏幕上的坐标
    x = int((screenWidth - winWidth)/ 2)
    y = int((screenHeight - winHeight) / 2)
    
    # 设置主窗口标题
    window.title("RadioButton参数说明")
    # 设置主窗口大小
    window.geometry("%sx%s+%s+%s" % (winWidth, winHeight, x, y))
    # 设置窗口宽高固定
    window.resizable(0,0)
    # 设置窗口图标
    window.iconbitmap("./image/icon.ico")
    
    """radiobutton参数.
