如上图所示，点击对象时可实现亮显效果，请问arx如何实现亮显一个实体？

LoveArx

显示夹点？ LISP怎么做，ARX一样

acedSSSetFirst Global Function int

acedSSSetFirst(

const ads_name pset,

const ads_name unused);

pset Set of entities to be added to the pickfirst selection set and on which grips will be displayed
unused Ignored

This function sets which objects are selected and gripped.

The parameters have the following data type definition:

typedef long ads_name[2];

The selection set of objects specified by the gset argument are gripped, and the selection set of objects specified by pset are both gripped and selected. If any objects are common to both selection sets, acedSSSetFirst() grips and selects the selection set specified by pset only (it does not grip the gset set).

If gset is NULL and pset is specified, acedSSSetFirst() grips and selects pset. If gset and pset are NULL, acedSSSetFirst() turns off any existing grips and selections.

You are responsible for creating a valid selection set. For example, you may need to verify that a background paper space viewport (DXF group code 69) is not included in the selection set. You may also need to ensure that selected objects belong to the current layout.

Note The addCommand() optional flags ACRX_CMD_USEPICKSET and ACRX_CMD_REDRAW must be used in order for acedSSSetFirst() to work.

Do not call acedSSSetFirst() when AutoCAD is in the middle of executing a command.

谢谢指导！
下面代码可实现将选择的标注亮显
        static void YTMsupportF1(void)
        {
                // Add your code for command YTMsupport.F1 here
                ads_name sset;////选择集名称
                //建议缓冲区链表
                struct resbuf *rb;//结果缓冲表
                rb=acutBuildList(RTDXF0,_T("DIMENSION"),RTNONE);
                if(acedSSGet(NULL,NULL,NULL,rb,sset)==RTNORM)//if(acedSSGet(_T("X"),NULL,NULL,rb,sset)==RTNORM)
                {
                        long length=0;
                        acedSSLength(sset,&length);
                        acutPrintf(TEXT("\n实体数:%d"),length);
                        acedSSSetFirst(sset,NULL);                       
                }
                else
                {
                        acutPrintf(_T("\n您退出了程序!"));
                }
                //关闭链表
                acutRelRb(rb);
                //关闭选择集
                acedSSFree(sset);
        }
