    项目结构可以通过文件夹的方式分类，不过要注意引入头文件的时候也要加上文件夹名称。 如果不想多一层文件夹，就需要设置INCLUDEPATH。

    sendWriteRequest(mdu, address);会自动创建个新的qmodbusreply 的对象，我怀疑这个对象没有释放导致的，但是试了很多方法都不行，不知道楼主是怎么解决的？？

    代码是单线程的，使用qApp->processEvents(); reply=NULL, 也没有让内存停止上涨

    造成卡顿的原因可以考虑以下几个方面： 添加数据时，在主线程大量new QStandardItem造成阻塞。可以将生成数据放置于子线程或利用qt concurrent。注意qobject不是线程安全的，不要在其他线程操作model，应该在替他线程生成好QStandardItem数据集合，在主进程添加到model中。

    @yangyangyang said in LGPL: 我们需要使用QTCharts组件，但QT Charts仅有GPL的版本，请问QT有LGPL版本的其他接口或组件可替代QTcharts吗？ 请看看 https://qwt.sourceforge.io/
