python3GUI--翻译器By:PyQt5（附源码）

---

前面用TK写过两款翻译器GUI，都是基于google_trans_new这个第三方模块写的，由于google_trans_new方法更新了，加之最近在学习PyQt5，在之前布局的基础上稍加改进，使用了一些QSS，设计了一下组件的布局，整体感觉比较清新小巧，开始~

一．准备工作

1. 基于PyQt5的QT设计师，安装、配置详见：

PyCharm安装PyQt5及其工具（Qt Designer、PyUIC、PyRcc）详细教程

2. 本次翻译仍然依赖第三方翻译模块：google_trans_new。

pip install google_trans_new

使用pip安装完成后，是不能直接用的，需要修改一行代码，详细操作参考

python3–最新google_trans_new超时报错JSONDecodeError解决

二．预览

1.启动

整体采用垂直布局。

2.选择语言

内置209种语言，默认自动选择翻译目标语言。

3.翻译

这里我选择了英语语当做目标语言，翻译准确，速度快。

三．设计流程

1.整体流程

1.UI设计(草图)

组件布局采用整体垂直布局，局部水平布局，支持窗口的缩放。

3.UI设计（QT设计师）

有了草图，在QT设计师里设计界面就简单了。

四．源代码

1. My_translator.py（主界面调动）

五．总结

本次使用PyQt5制作了一款简单小巧的翻译器，支持超过200种语言的翻译，同时也支持文本文件翻译，在测试中没有发现什么问题，使用QSS对部分组件设计了样式，加了伪状态，用户体验有所提升，翻译器的话不打算再做下去了，但是PyQt5的路我还要一直走下去。程序打包好放在了蓝奏云。思路、代码方面有什么不足欢迎各位大佬指正、批评！能点个赞给我个鼓励吗？
