Problem with custom blockReference

Anonymous — Mon, 25 May 2020 10:36:57 GMT

Hi,

I made a class inherited from AcDbBlockReference:

class PICBlock : public AcDbBlockReference { public: ACRX_DECLARE_MEMBERS(PICBlock); static void makeMembers(AcRxMemberCollectionBuilder& collectionBuilder, void* customData); protected: static Adesk::UInt32 kCurrentVersionNumber; public: PICBlock(); PICBlock(const AcGePoint3d& position, AcDbObjectId blockTableRec); Acad::ErrorStatus dwgOutFields(AcDbDwgFiler* pFiler) const final; Acad::ErrorStatus dwgInFields(AcDbDwgFiler* pFiler)final; Acad::ErrorStatus dxfOutFields(AcDbDxfFiler* pFiler) const final; Acad::ErrorStatus dxfInFields(AcDbDxfFiler* pFiler)final; Acad::ErrorStatus subClose()override; void setManagedWrapper(gcroot<Autodesk::PIC::MgPICBlock^> p); private: gcroot<Autodesk::PIC::MgPICBlock^> m_pManaged; // the managed wrapper pointer. }; Adesk::UInt32 PICBlock::kCurrentVersionNumber = 1; ACRX_DXF_DEFINE_MEMBERS_WITH_PROPERTIES( PICBlock, AcDbBlockReference, AcDb::kDHL_CURRENT, AcDb::kMReleaseCurrent, AcDbProxyEntity::kNoOperation, PIC-BLOCK, PICBLOCK "|Product Desc: PIC-ACAD" "|Company: So.Build" "|WEB Address: www.sobuild.fr", PICBlock::makeMembers ) void PICBlock::makeMembers( AcRxMemberCollectionBuilder& collectionBuilder, void* customData) { readFromResource("PIC_Attributs.xml", collectionBuilder); } PICBlock::PICBlock() : AcDbBlockReference() { // } PICBlock::PICBlock(const AcGePoint3d& position, AcDbObjectId blockTableRec) : AcDbBlockReference(position, blockTableRec) { // } Acad::ErrorStatus PICBlock::dwgOutFields(AcDbDwgFiler* pFiler) const { Acad::ErrorStatus retStat = AcDbBlockReference::dwgOutFields(pFiler); if (retStat != Acad::eOk) return retStat; retStat = pFiler->writeUInt32(PICBlock::kCurrentVersionNumber); return retStat; } Acad::ErrorStatus PICBlock::dwgInFields(AcDbDwgFiler* pFiler) { assertWriteEnabled(); Acad::ErrorStatus retStat = AcDbBlockReference::dwgInFields(pFiler); if (retStat != Acad::eOk) return retStat; Adesk::UInt32 uiVersion = 0; retStat = pFiler->readUInt32(&uiVersion); return retStat; } Acad::ErrorStatus PICBlock::dxfOutFields(AcDbDxfFiler* pFiler) const { Acad::ErrorStatus retStat = AcDbBlockReference::dxfOutFields(pFiler); if (retStat != Acad::eOk) return retStat; retStat = pFiler->writeUInt32(AcDb::kDxfInt32, PICBlock::kCurrentVersionNumber); return retStat; } Acad::ErrorStatus PICBlock::dxfInFields(AcDbDxfFiler* pFiler) { assertWriteEnabled(); Acad::ErrorStatus retStat = AcDbBlockReference::dxfInFields(pFiler); if (retStat != Acad::eOk) return retStat; resbuf data; Adesk::UInt32 uiVersion = 0; retStat = pFiler->readItem(&data); if ((data.restype != AcDb::kDxfInt32) || (retStat != Acad::eOk)) return (retStat != Acad::eOk) ? retStat : Acad::eNotApplicable; uiVersion = data.resval.rint; return retStat; } Acad::ErrorStatus PICBlock::subClose() { Acad::ErrorStatus es; if ((es = AcDbBlockReference::subClose()) != Acad::eOk) return es; if (isWriteEnabled() == Adesk::kTrue) { //You have to cast it back to the managed type to do a null check: if (static_cast<Autodesk::PIC::MgPICBlock^>(m_pManaged) != nullptr) { // Call the method on the wrapper which will propagate to all managed // listeners of this event... m_pManaged->PICBlockModified(ToObjectId(objectId())); } } return Acad::eOk; } void PICBlock::setManagedWrapper(gcroot<Autodesk::PIC::MgPICBlock^> p) { m_pManaged = p; } ACDB_REGISTER_OBJECT_ENTRY_AUTO(PICBlock)

but I can't have attributes I have an exception "illegal entity type"

and I can't create a dynamic block.

What I'm doing wrong ?

Thanks.

Classes derived from AcDbBlockReference cannot have AcDbAttributes.
