闭合m_pPolygon删除线段实体
CSouthDrawPolygonDynamicCom *obj
定义字符串m_beginCmd = \"beginDrawPolygon\";m_moveCmd = \"moveDrawPolygon\";m_appendCmd = \"appendPolygonPoint\";m_stopCmd = \"stopDrawPolygon\";m_cancelCmd = \"cancelDrawPolygon\";定义geojson的TypegeoJson.m_geometry.m_type = \"Point\";
const QJsonObject msgData
清空geojson里面的m_coordinates数据将m_point添加到geoJson里面转换为字符串再转换为QJsonObject赋值给msgData

返回实体*entity
构造函数
定义一个CSouthDrawPolygonJig对象obj调用obj的SetCallBackObj传入本命令的对象指针的接口对象调用obj的doIt()开始绘制面积线
MoveTo(const AcGePoint2d& point)
type==m_cancelCmd
Append(const AcGePoint2d& point)
QJsonObject &msgData
动态绘制面积线，有五个步骤Start、MoveTo、Append、Stop、Cancel，这几个方法继承于CSouthDrawPolygonDynamicCom(接口)，在动态绘制面积线反应器类CSouthDrawPolygonJig中被调用，从而实现动态绘制面积线，并通过五个接口发送数据，实现在gis里面同步绘制面积线的功能
设置m_pLine终点为m_ept刷新图像(线段终点跟随鼠标移动)
采样sampler
基类AcEdJig(基类)
type==m_stopCmd
调用父类构造函数CSouthSocketCommand(\"GisDoubleWindow_DrawPolygonDynamic\")
m_obj = obj
回调obj->Stop()闭合面积线结束循环
Cancel()
删除线段实体和面积线实体

//发送开始画面积线的命令m_point = point;geoJson.m_geometry.m_type = m_beginCmd;sendMsg();
执行绘制doIt
关闭m_pPolygon实体
将msgData转换为字符串，再转换为SouthGeoJson取出第一个点数据赋值给m_ept和geoJson.m_geometry.m_type赋值给type
//发送每一个面积线的端点m_point = point;geoJson.m_geometry.m_type = m_appendCmd;sendMsg();
type==m_moveCmd
动态绘制面积线接口CSouthDrawPolygonDynamicCom(接口)
//发送绘制面积线结束的命令geoJson.m_geometry.m_type = m_stopCmd;sendMsg();
(面积线更新，线段更新起点)设置m_pLine起点为m_ept将m_ept添加到 m_pPloygon里面刷新图像
Append
//发送移动的命令m_point = point;geoJson.m_geometry.m_type = m_moveCmd;sendMsg();
//发送取消绘制的命令geoJson.m_geometry.m_type = m_cancelCmd;sendMsg();
