ObjectARX 实体双击之消息截获

高版本的双击参杂了cui自定义双击处理，继承AcDbDoubleClickEdit的双击协议可能无效，因此可以尝试从消息处理

代码

bool filterMouse(MSG *pMsg)
{if( pMsg->message == WM_LBUTTONDBLCLK ){ads_name ss;if(RTNORM != acedSSGet(_T("I"),NULL,NULL,NULL,ss)){return false;}ads_name ent;acedSSName(ss,0,ent);acedSSFree(ss);AcDbObjectId objId;acdbGetObjectId(objId,ent);CString strDxf= objId.objectClass()->dxfName();if (strDxf == _T("MTEXT")){//acutPrintf(_T("\n自定义处理"));bool bIsMtext=false;acDocManager->lockDocument(curDoc());AcDbObjectPointer<AcDbMText>pMtext(objId,AcDb::kForRead);if(Acad::eOk == pMtext.openStatus()){if (pMtext->colorIndex() == 1){bIsMtext=true;pMtext->close();}}acDocManager->unlockDocument(curDoc());if (bIsMtext){acDocManager->sendStringToExecute(curDoc(),_T("_properties "));//截断消息return true;}			}		}//消息继续传递return false;
}
