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
)
