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;

"64s" # TCHAR szInfoTitle[64]; 气球提示标题

"I" # DWORD dwInfoFlags; 气球提示图标

)

)

UpdateWindow(self.hwnd)

icon_flags = win32con.LR_LOADFROMFILE | win32con.LR_DEFAULTSIZE

try:

except:
