返回IMxDrawCustomEntity对象
例如: JS代码
var ent = mxOcx.DrawCustomEntity("TestMxCustomEntity", "");
ent.SetPoint("spt", frstPt);
ent.SetPoint("ept", secondPt);例如: VC COM
void CTestVc2005Dlg::DoCustomEntity() { // TODO: 在此添加控件通知处理程序代码 MxDrawXLib::IMxDrawUiPrPointPtr getPt; getPt.CreateInstance(__uuidof( MxDrawXLib::MxDrawUiPrPoint )); IMxDrawUiPrPoint* pGetPt = getPt; pGetPt->put_message(_T("点取第一点")); if(pGetPt->go() != mcOk) return; IMxDrawPointPtr frstPt = pGetPt->value(); if(frstPt == NULL) return; MxDrawXLib::IMxDrawUiPrPointPtr getSecondPt; getSecondPt.CreateInstance(__uuidof( MxDrawXLib::MxDrawUiPrPoint )); pGetPt = getSecondPt; pGetPt->put_message(_T("点取第二点")); pGetPt->put_basePoint(frstPt); pGetPt->setUseBasePt(VARIANT_TRUE); if(pGetPt->go() != mcOk) return; IMxDrawPointPtr secondPt = pGetPt->value(); if(secondPt == NULL) return; IDispatchPtr spObj(m_ocx.DrawCustomEntity(MX_CUSTOM_ENTITY_ID,NULL),false); CComPtr<IMxDrawCustomEntity> spEntity; spObj->QueryInterface(&spEntity); if(spEntity == NULL) return; spEntity->SetPoint(_T("spt"),frstPt); spEntity->SetPoint(_T("ept"),secondPt); }
