  @linxisuo said in QSerialPort线程: 使用QSerialPort进行串口通信，在主线程中new一个QSerialPort，并连接好指定串口。在主线程中可以正常通信，传入子线程中就不能使用。 QT大多数的类都不是线程安全的，需要在主线程使用

  @kaomop 前段时间用 qtwinmigrate 把一个基于 QGraphicsView 的控件嵌入到 MFC 对话框中，能成功，但是效果还要细调。qtwinmigrate 有点老了，特地装了 Qt 5.6 才编译通过。至于把 MFC 窗口嵌入到 Qt 没有试过。 如果是一个长期维护的项目，建议还是用纯 Qt

  初步猜测是因为不同的运行平台，加载库的线程不同导致的。Qt下运行在QAbstractProxyModel下，C#winform加载库运行在RtlUserThread。 对于我这种小白来说，QtCore的库不能很好解决这个问题。 参考：link[https://github.com/itas109/CSerialPort]，在此我谢谢相关作者。 虽然封装的不太标准，取缓存数据也不太优雅，终归能跨平台调用，能够解决问题。
