利用Python编写一个Windows桌面小组件

import tkinter as tk
import time

def update_clock():
    current_time = time.strftime("%H:%M:%S")
    label.config(text=current_time)
    label.after(1000, update_clock)

def exit_app():
    window.destroy()

# 创建窗口
window = tk.Tk()
window.title("桌面小组件")

# 设置窗口为无边框
window.overrideredirect(True)

# 设置窗口透明度
window.attributes('-alpha', 0.7)  # 设置透明度为 0.7

# 创建标签
label = tk.Label(window, font=("Arial", 80), fg="black")
label.pack(padx=50, pady=50)

# 更新时钟
update_clock()

# 创建菜单
menu = tk.Menu(window, tearoff=0)
menu.add_command(label="退出", command=exit_app)

# 绑定鼠标右键事件
def show_menu(event):
    menu.post(event.x_root, event.y_root)

window.bind("<Button-3>", show_menu)

# 实现拖动功能
def start_drag(event):
    window.x = event.x
    window.y = event.y

def drag(event):
    deltax = event.x - window.x
    deltay = event.y - window.y
    new_x = window.winfo_x() + deltax
    new_y = window.winfo_y() + deltay
    window.geometry(f"+{new_x}+{new_y}")

window.bind("<ButtonPress-1>", start_drag)
window.bind("<B1-Motion>", drag)

# 运行窗口循环
window.mainloop()
