[求助]用例子的getsubentpathsatgsmarker无法遍历子实体
今天用arx里的例子遍历region的各个边,发现只能找到一个边,为什么呢?
ads_name sset;
if (acedssget("_:s", null, null, null, sset) != rtnorm) {
return acad::einvalidadsname;
}
struct resbuf *prb;
acedssnamex(&prb, sset, 0);
acedssfree(sset);
struct resbuf *ptemp;
int i;
for (i=1, ptemp = prb;i<3;i++, ptemp = ptemp->rbnext)
{ ; }
ads_name ename;
ads_name_set(ptemp->resval.rlname, ename);
ptemp = ptemp->rbnext;
marker = ptemp->resval.rint;
acutrelrb(prb);
acdbgetobjectid(objid, ename);
acdbentity *pent;
acdbopenacdbentity(pent, objid, acdb::kforread);
acgepoint3d pickpnt;
acgematrix3d xform;
int numids;
acdbfullsubentpath *subentids;
pent->getsubentpathsatgsmarker(acdb::kedgesubenttype,
marker, pickpnt, xform, numids, subentids);
for( i = 0; i < numids; i++) {
pent->highlight(subentids[i]);
pent->unhighlight(subentids[i]);
}
delete []subentids;
pent->close();
调试的时候发现numids的值怎么是1呢?为什么只得到一个边?
