How to get name of inherited class of selected entity

majklha — Tue, 15 Oct 2024 09:59:30 GMT

If I select entity from DWG, by ssgeg function, I have a general entity pointer (AcDbEntity* pEntity). How I get a real class name of this netity (eg. AcDbLine or AcDbText, etc...). Like string.

pEntity->className() return "AcDbEntity"

pEntity->isA()->desc()->className() return some unsence ("AcRxObject").

I, of course, dont know, what type pEntity is. I cannot use AcDbLine::desc(pEntity).....

Thanks.

static auto entsel() { AcGePoint3d pnt; ads_name name = { 0L }; int res = acedEntSel(L"\nSelect it: ", name, asDblArray(pnt)); AcDbObjectId id; if(auto es = acdbGetObjectId(id, name); es != eOk) return std::make_tuple(Acad::PromptStatus::eError, id, pnt); return std::make_tuple(Acad::PromptStatus(res), id, pnt); } static void AcRxMyApp_idoit(void) { auto [es, id, pnt] = entsel(); if (es == Acad::PromptStatus::eNormal) { AcDbEntityPointer pEnt(id); acutPrintf(pEnt->isA()->name()); } }

easy reply is:

pEntity->isA()->name();

Of course, thank you. I forgot...

Sorry, it shouldn't be any irony. Your answer has been very helpful.

Hello! The result is AcDbLine or AcDbText. Can I get Line or Text? A zero value similar to DXF。thank you！

This should return the dxf name

pEnt->isA()->dxfName()
