c++ 样式错误 “Unknown property transition” /“Could not parse stylesheet of object 0xb88164f8”

解决办法

1. 通过遍历所有的控件，

• “Unknown property transition

2. 打印出所有的控件地址，将地址 GPS 2>&1 log.log 输出到log日志中

• “Could not parse stylesheet of object 0xb88164f8”

3. 关键函数QString getWidgetHierarchy(QObject* widget) 获得所有的控件
