Linux桌面鼠标取词自动翻译

浅浅的花香味﹌ 2022-08-27 11:46 218阅读 0赞

# 说明： #

鉴于linux环境下没有像有道词典一样好用的自动取词翻译的软件，所以决定自己写一个，方便看文档的时候，随时翻译。

程序基于Python 完成。环境fedora20.

# 准备阶段： #

需要安装三个程序，需要用xclip命令获得取词后获得的文本内容。用xlib库获取鼠标取词后完成后的瞬间动作。用pynotify用来气泡弹出翻译结果。

yum install xclip
    yum install python-xlib
    yum install python-notify

关于Xlib的相关信息见：http://blog.csdn.net/celte/article/details/28240829
