  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。。。

  我也发现了这个问题，我的*.a库是使用mingw32-make编译的，为了兼容qt5.12.1，我还专门使用qt5.12.1的mingw32-make去重新编译了一遍*.a库，还是不行，使用5.11.3或以下版本都可以使用。

  需要把Qt开发环境中的Audio 目录拷贝到你程序的运行路径，就可以解决此问题。
