标签:行选中 sys.argv .data 信息 trigger where visible sele ade 使用的软件: 代码(干货来了,之后会不定时更新): 样式表:stylesheet.qss 数据库 db QT的样式表使用起来确实很方便,但是觉的打开软件的时候会变慢所以在代码里注释掉了 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’。 快捷方式管理(pyqt5升级版) python pytq5 标签:行选中 sys.argv .data 信息 trigger where visible sele ade 原文地址:http://blog.51cto.com/ikezcn/2166426
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。
python3.6
pyqt5 安装:pip insatll pyqt5
