halcon将Qt的label设置成Halcon的窗口

在QtCreator中

    HTuple hv_WindowHandle;
    Hlong windID;
    QLabel* label;
    HObject ho_Image;

    label=new QLabel(this);
    label->resize(400,300);
    windID = (Hlong)this->label->winId(); //获取label句柄
    OpenWindow(0,0,label->width(),label->height(),windID,"visible","",&hv_WindowHandle);
    //把label转换成halcon窗口

    ReadImage(&ho_Image, "D:/bb/tu/ma.jpg");
    HTuple hv_Width,hv_Height;
    GetImageSize(ho_Image, &hv_Width, &hv_Height);//获取图像的宽和高
    SetPart(hv_WindowHandle,0, 0, hv_Height-1, hv_Width-1);//修改图像在激活窗口的显示区域
    DispObj(ho_Image, hv_WindowHandle);
