elementaryOS系统托盘解决方案

在用 eOS 的时候，你可能会遇到系统托盘的问题，有些需要托盘的软件比如说 QQ，没办法在 eOS 的 Wingpanel 上显示，一最小化就不见了，或者出现一个 System tray 的窗口，很麻烦。这是由于 elementaryOS 是没有系统托盘的，只有 Wingpanel，如果软件没有 appindicator，就不会显示在 Wingpanel 上显示，这是官方解释。本文章提供一种不是很完美的解决方案，能暂时解决系统托盘问题。

我的博客原文：

python-appindicator

python-appindicator只对python写的程序有用，比如goagent、dropbox。打开终端并输入：

sudo apt-get install python-appindicator

安装完成之后，便可以显示python程序的托盘。

stalonetray

但是其它非python的程序也无法显示在Wingpad上，博主也找不到办法让它们显示在Wingpad上，但是有一种折中的解决方案。就是把系统托盘独立出来，需要用到stalonetray，安装可参考这里。默认是显示在左上方，需要修改一下配置文件~/.stalonetrayrc。

这里介绍几个重点的，这是我自己的配置文件：

geometry 1x1+2+30      ＃这个是位置及初始化大小，我这里的大小是1x1，坐标为(+2,+30)，其+表示左边与上边，－表示下边与右边
transparent true       #是否透明
window_layer bottom    #窗口的层次
slot_size 24           #托盘图标占用的大小
icon_size 16           #显示图标大小

这是效果图：
