Jakarta ee 制作4窗口视频会议，不能拖动

如何制作4窗口视频会议并使其不能拖动？我已经更改了commonVideoViewContentSWF10.lzx中的代码，但我无法将其更改为4视频会议。谢谢你

<method name="getNewVideoObjectByPos" args="publicSID">
    <![CDATA[
        var obj = this.getVideoObjectByPublicSID(publicSID);
        if (obj!=null){
            return obj;
        }

        //Get a Free VideoView Slot
        var freePos = this.getVideoObjectFreePos(40, 396, 360);


        return new lz.videoObjectPlayBroadcast(this,{
                publicSID:publicSID,
                width:videoWidth,
                height:videoHeight,
                x:freePos[0],
                y:freePos[1],
                isInterview:canvas.isInterview

            });

    ]]>
