快捷方式管理（pyqt5升級版）附代碼純乾貨 pytq5 python3.6.0-32

之前用python寫了個小軟件https://blog.51cto.com/ikezcn/2142638
說實話用tk的話界面確實不好看,所以需要改進,看了pyqt5的介紹想要試一下，對於上次寫的軟件來說這裏只是更改了界面而已。上面的程序不再更新。

使用的軟件：
python3.6
pyqt5 安裝:pip insatll pyqt5

界面：

代碼(乾貨來了，之後會不定時更新)：

# -*- coding: utf-8 -*-
#v2.0 2018-08-30更新
#v2.1 2018-08-31更新
#現在可以使用pyinsatller打包了，新增了樣式表，就算沒有數據庫也會自己創建並增加數據表,隱藏列名
#v2.2 2018-09-05更新
#增加了左邊一列用來做查詢條件,雙擊就可以搜索.
#右鍵右邊的路徑可以添加搜索條件.
#最後遇到一個問題:多次使用setFilter會造成模型出現問題導致無法寫入數據庫,這裏就直接跳過模型自己插入數據庫
#v2.3 2018-09-06更新
#增加刷新菜單,顯示所有路徑,修復bug
#v2.4 2018-09-11更新
#小修小補

QT的樣式表使用起來確實很方便，按CSS做的很多地方都是一樣的，代碼裏有qt官網的樣式表介紹連接

說說PYQT5與TK的使用感覺，TK上手方便，拿起來就能寫，PYQT5需要了解它的工作機制所以上手時間會比較長。比較喜歡qss、tableview、tablemodel，qss可以很方便的調整樣式而且和js很像，用過js的上手那叫一個快，tableview與tablemodel聯動可以少些很多代碼，最主要的它的容錯度很高，有些可以不用寫try也不會造成程序停止運行，這點很重要，哈哈，重要的點就在於‘懶’。

程序打包之後可以直接修改stylesheet.qss，樣式一樣會改變好方便，可以做定製，贊。
