之前用python写了个小软件https://blog.51cto.com/ikezcn/2142638
说实话用tk的话界面确实不好看,所以需要改进,看了pyqt5的介绍想要试一下，对于上次写的软件来说这里只是更改了界面而已。上面的程序不再更新。
使用的软件：
python3.6
pyqt5 安装:pip insatll pyqt5
界面：
代码(干货来了，之后会不定时更新)：
# -*- coding: utf-8 -*-
#v2.0 2018-08-30更新
#v2.1 2018-08-31更新
#现在可以使用pyinsatller打包了，新增了样式表，就算没有数据库也会自己创建并增加数据表,隐藏列名
#v2.2 2018-09-05更新
#增加了左边一列用来做查询条件,双击就可以搜索.
#右键右边的路径可以添加搜索条件.
#最后遇到一个问题:多次使用setFilter会造成模型出现问题导致无法写入数据库,这里就直接跳过模型自己插入数据库
#v2.3 2018-09-06更新
#增加刷新菜单,显示所有路径,修复bug
#v2.4 2018-09-11更新
#小修小补

}QT的样式表使用起来确实很方便，按CSS做的很多地方都是一样的，代码里有qt官网的样式表介绍连接
说说PYQT5与TK的使用感觉，TK上手方便，拿起来就能写，PYQT5需要了解它的工作机制所以上手时间会比较长。比较喜欢qss、tableview、tablemodel，qss可以很方便的调整样式而且和js很像，用过js的上手那叫一个快，tableview与tablemodel联动可以少些很多代码，最主要的它的容错度很高，有些可以不用写try也不会造成程序停止运行，这点很重要，哈哈，重要的点就在于‘懒’。
程序打包之后可以直接修改stylesheet.qss，样式一样会改变好方便，可以做定制，赞。
