经过测试（将QT的 mingw73_64下面的plugins/sqldrivers目录下的sqlite驱动拷贝到QTitanRibbon的bin目录sqldrivers子目录下，覆盖原来的SQLITE驱动文件），运行程序，同样出现“cannot mix incompatible Qt library (version 0x50c00) with this library (version 0x50d00)”的错误，应该是驱动程序在编译的时候（使用QTitanRibbon 5.10）做了特殊处理，这才导致问题的发生。
有什么可以解决呢？

@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

这个页面你需要点一下那个<新类>，然后才能输入类名称，进行之后的操作。

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。

這網站好像沒什麼人在回覆喔??
我找到人幫我解答，大家參考看看吧!!
QGraphicsScene *scene = new QGraphicsScene;
scene->addWidget(new QSvgWidget("../untitled6/splash1.svg"));
scene->addWidget(new QSvgWidget("../untitled6/splash2.svg"));
ui->graphicsView->setScene(scene);
看大家能不能繼續解答下去，我要如何將載入的svg檔案，定義尺寸大小與去除背景色(原檔是無底色)

@wigntianyu said in QT5.8 QNetworkDiskCache 缓存时间设置:
QNetworkDiskCache
QNetworkDiskCache没有超时设置，只有缓存大小的设置，默认是50M，估计是缓存满了清空了。
可以设置setMaximumCacheSize大一些试试。

自定义View和Model，实现一种懒加载的机制。
当滑动View的时候通知Model去加载一到两页（根据可视范围来确定每页的数据量）。
大数据量加载列表，无非就是翻页设计或者懒加载。。。
