我的结构体

类似这样
typedef struct _IplImage
{
...........
    struct _IplTileInfo *tileInfo;  /* "           " */
    int  imageSize;         /* Image data size in bytes
                               (==image->height*image->widthStep
                               in case of interleaved data)*/
    char *imageData;        /* Pointer to aligned image data.         */
    int  widthStep;         /* Size of aligned image row in bytes.    */
    int  BorderMode[4];     /* Ignored by OpenCV.                     */
    int  BorderConst[4];    /* Ditto.                                 */
    char *imageDataOrigin;  /* Pointer to very origin of image data
                               (not necessarily aligned) -
                               needed for correct deallocation */
.............
}
IplImage;

发送函数
我实验了几种
QTextStream 不支持自定义的结构体类型
然后我实验write
用char *的方式传输
也不行

m_clientTcpSocket的类型是 QTcpSocket

void VideoServer::sendData(IplImage image)
{
    if (!client_flag ) createClient();
   // QTextStream out(m_clientTcpSocket);

    //out << image << endl;
    m_clientTcpSocket->write((const char *)&image,sizeof(IplImage));
}

qt有什么好的方法吗？
