QtHalcon控件HWindowmouseMove事件截获如何传到下面Widget重

怎么处理这个问题？Qt里面设置了mouseTracking(true)没用

void WindowController::mouseMoveSlot(QMouseEvent *event)
{
        HTuple _row, _col,_buuuton;
        double _movX, _movY;
        Qt::MouseButton _btn = event->button();
        if (_btn == Qt::RightButton)
                return;
        HTuple _channelcount;
        HTuple _r = 0, _g = 0, _b = 0;
        HObject _channelred, _channelgreen, _channelblue;
        if (imageWidth == 0 || imageHeight == 0)
                return;
        //ConvertCoordinatesWindowToImage(windowHand, event->y(), event->x(), &_row, &_col);
        //emit OnMouseMovePoint(imageWidth, imageHeight, _col.D(), _row.D(), _r.I(), _g.I(), _b.I());
        emit OnMouseMovePoint(imageWidth, imageHeight, event->x(), event->y(), _r.I(), _g.I(), _b.I());

设置鼠标穿透  吗
