U盘制作启动盘工具

最近项目需要用QT开发组织架构图，本来先网上找个demo拿来即用，但是找了一圈，要么不能编译，要么运行崩溃，要么很粗糙什么细节都没做，离实际应用差距甚远。于是我自己重新编写调试，耗费几天时间，在Window10 X64上运行，五层级别，右键增加或删除节点 会自动调整位置，也可以重置，双击可修改节点，鼠标滑过可以展现部门职位信息，按住鼠标左键可以移动视图，鼠标滚轮可以缩放试图。数据会自动保存到SQlite，下次打开会读取加载数据。

win7旗舰版升级成win10系统，出现错误代码 0X80072F8F - 0X20000 ，先下载运行“Easy fix 51044”，再下载安装"Media creation tool21H2.exe"
