Python实现Windows上气泡提醒效果的方法

本文实例讲述了Python实现Windows上气泡提醒效果的方法。分享给大家供大家参考。具体实现方法如下：

# -*- encoding: gbk -*-
import sys
import os
import struct
import time
import win32con
from win32api import *
# Try and use XP features, so we get alpha-blending etc.
try:
 from winxpgui import *
except ImportError:
 from win32gui import *
class PyNOTIFYICONDATA:
 _struct_format = (
  "I" # DWORD cbSize; 结构大小(字节)
  "I" # HWND hWnd; 处理消息的窗口的句柄
  "I" # UINT uID; 唯一的标识符
  "I" # UINT uFlags;
  "I" # UINT uCallbackMessage; 处理消息的窗口接收的消息
  "I" # HICON hIcon; 托盘图标句柄
  "128s" # TCHAR szTip[128]; 提示文本
  "I" # DWORD dwState; 托盘图标状态
  "I" # DWORD dwStateMask; 状态掩码
  "256s" # TCHAR szInfo[256]; 气泡提示文本
  "I" # union {
    #  UINT uTimeout; 气球提示消失时间(毫秒)
    #  UINT uVersion; 版本(0 for V4, 3 for V5)
    # } DUMMYUNIONNAME;
