[PYQT]QSS使用，附自己的模板（算是扒OSX UI）

题记

最近在做Python GUI开发，一直觉得自己的界面LOW爆了，所以想找一些好的资源，但真心没有太好的，最终只找到一个QSS编辑器，一个API，一个OSX的Sketch资源文件。就有了这个QSS文件，本人没有UI经验，调整了一套，算是对自己一个交待吧。
一个QSS编辑器：https://github.com/hustlei/QssStylesheetEditor
QssStylesheetEditor支持预览，控件很全。
一个API：https://doc.qt.io/qt-5/stylesheet-examples.html 官方例子。能用的都有了。
源文件的位置在码云：https://gitee.com/aocshallo/mac-qss.git
