从 QResource 中缓冲原始数据?
原标题:Buffering the raw data from a QResource?

我正在用 Qt 创建一个 3D 模型装载器。

我想利用Qt资源系统 用来装货模型等等

我想做类似这样的语法:

Mesh* MeshLoader::loadMesh(const QString& resource) {
    QResource qResource(resource);
    QResource::registerResource(resource); 
    SomeBuffer buffer(qResource.data())
    while (!buffer.eof()) { 
        // Process the file
    }
    QResource::unregisterResource(resource);
}

有什么建议吗?

你所加入的代码有什么问题?

仅作为注释 : 您可以使用 Qt 资源符号( 路径中的前导 : ), 并使用几乎所有 Qt 数据/ 流读器。 例如, 您可以使用 QFile (":/ 某些资源" ) 。 如果使用 QFile 和 QDataStream, 我想( 但也许我错了), 您只能读取文件的块块, 而不装入整个资源并在读取时屏蔽线索。 如果它封住主线, 您可以使用 QRunnable 或 QTread 在背景中装入资源 。

对于缓冲:我不知道Qt(网络相关部分除外)中含有任何缓冲解决方案,所以你也许应该自己执行。

这样您就可以建立一个 MyResources 类, 该类将目标资源装入背景线, 并在完成后用信号/ 绘图通知, 并可以按照您想要的方式缓存资源数据 。
