本文實例講述了Python實現Windows上氣泡提醒效果的方法。分享給大家供大家參考。具體實現方法如下：

# -*- 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:

class PyNOTIFYICONDATA:

_struct_format = (

"I" # DWORD cbSize; 結構大小(字節)

"I" # HWND hWnd; 處理消息的窗口的句柄

"I" # UINT uID; 唯一的標識符

"I" # UINT uFlags;

"I" # UINT uCallbackMessage; 處理消息的窗口接收的消息

"I" # HICON hIcon; 托盤圖標句柄

"128s" # TCHAR szTip[128]; 提示文本

"I" # DWORD dwState; 托盤圖標狀態

"I" # DWORD dwStateMask; 狀態掩碼

"256s" # TCHAR szInfo[256]; 氣泡提示文本

"I" # union {

# UINT uTimeout; 氣球提示消失時間(毫秒)

# UINT uVersion; 版本(0 for V4, 3 for V5)

# } DUMMYUNIONNAME;

"64s" # TCHAR szInfoTitle[64]; 氣球提示標題

# Create the Window.

self.hwnd = CreateWindow(classAtom, "Taskbar Demo", style,

)

UpdateWindow(self.hwnd)

icon_flags = win32con.LR_LOADFROMFILE | win32con.LR_DEFAULTSIZE

try:

except:
