关于ubuntu中气泡提示的使用
我学校用的是港湾验证，使用起来很让人不爽，于是下定决心自己写linux下面的港湾客户端，熬了几天，写好了。
写成daemon程序，发现ubuntu里面的这个气泡提示很好，就网上淘了些资料，现在整理出来。
ubuntu的气泡提示是使用notify-osd来实现的，我们需要下载libnotify，
apt-get install notify-osd (ubuntu 已经自带）
apt-get install libnotify-dev
其实shell里面也可发送气泡提示，命令为notify-send，需要安装libnotify-bin
apt-get install libnotify-bin
usage:
notify-send Test "Hello World"
notify-send "Message Title" "The message body is shown here" -i /usr/share/pixmaps/apple-green.png -t 1000
ps:icon can be a png, xpm or jpg file
截图来看看：
C语言中，我们使用的是notify库，可查阅官方资料
Libnotify Reference Manual：
http://library.gnome.org/devel/libnotify/0.7/
一定要习惯阅读英文manual.多点看，慢慢就习惯了
我自己写的一个C文件：

测试一下函数：
/* file.c * Copyright (C) 2011 crazyleen <[email protected]>, All Rights Reserved. * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License version 2 as * published by the Free Software Foundation. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

效果还可以，正常显示，就是那个时间设置没起作用，每次都是系统默认的，这个气泡提示用于偶尔的消息通知挺好的，但是一定不能连续使用，因为这个冒泡显示是延时一点时间的，不能马上显示出下一条消息，必须等上一条消息淡化退出后才能显示下一条消息，这或许也算是一个bug吧
以下是我程序运行的效果
我把这个气泡提示用于mystar客户端，写成守护进程，开机自动运行，再也不用为linux下的802.1x验证而感到恼火了，呵呵
