python实现桌面气泡提示功能实现桌面气泡提示功能

在写桌面软件时，通常会使用到托盘上的泡泡提示功能，让我们来看看使用python如何实现这个小功能。

一、一、Linux系统系统

在Linux上，实现一个气泡提示非常简单，使用GTK实现的pynotify模块提供了些功能，我的环境是Ubuntu，默认安装此模块，如果没

有，下载源文件编译安装一个。实现代码如下：

#!/usr/bin/python

#coding:utf-8

import pynotify

pynotify.init ("Bubble@Linux")

bubble_notify = pynotify.Notification ("Linux上的泡泡提示", "看，比Windows上实现方便多了！")

bubble_notify.show ()

效果：

二、二、Windows下的实现下的实现

Windows下实现是比较复杂的，没有pynotify这样一个模块，找到了一个还算不错的模块（地址），这个类有些语法上的小问题，至少在

python2.6下如此，需要修改一下，如下是修改后的代码），基本可用，代码如下：

#!/usr/bin/env python

# -*- coding: utf-8 -*-

#gtkPopupNotify.py

# modified by NickCis 2010 http://github.com/NickCis/gtkPopupNotify

# Modifications:

# Added: * Corner support (notifications can be displayed in all corners

# * Use of gtk Stock items or pixbuf to render images in notifications

# * Posibility of use fixed height

# * Posibility of use image as background

# * Not displaying over Windows taskbar(taken from emesene gpl v3)

# * y separation.

# * font description options

# * Callbacks For left, middle and right click

Create a new notification stack. The recommended way to create Popup instances.

Parameters:

`size_x` : The desired width of the notifications.

`size_y` : The desired minimum height of the notifications. If it isn't set,

or setted to None, the size will automatically adjust

`timeout` : Popup instance will disappear after this timeout if there

is no human intervention. This can be overridden temporarily by passing

a new timout to the new_popup method.

`coner` : 2 Value tuple: (true if left, True if top)

`sep_y` : y distance to separate notifications from each other
