在arx中自定义实体遇到的问题
<P>我在arx中自定义了一个类，但在加到数据库的时候发生错误，想问一下是否需要什么注册的操作？是否只能在dbx中写啊？谢谢<BR>头文件</P><P>class EObject:public AcDbEntity<BR>{<BR>protected:<BR> char *m_name;<BR> Adesk::Int32 m_ID;<BR> char *m_location;<BR> AcGePoint3d m_center;</P>
<P>public:<BR> EObject();<BR> virtual ~EObject(){}<BR> virtual Adesk::Boolean worldDraw (AcGiWorldDraw *mode);<BR> virtual Acad::ErrorStatus getGeomExtents(AcDbExtents & extents);<BR> virtual Acad::ErrorStatus transformBy(const AcGeFastTransform& xform);<BR> virtual Acad::ErrorStatus getTransformedCopy(const AcGeMatrix3d &xform, AcDbEntity *&pEnt);<BR> virtual Acad::ErrorStatus getGripPoints(AcGePoint3dArray & gripPoints,AcDbIntArray &osnapModes,AcDbIntArray & geomIds) const;<BR> virtual Acad::ErrorStatus moveGripPointsAt(const AcDbIntArray &indices,const AcGeVector3d &offset);<BR>cpp文件</P>
<P><BR> </P> <P> EObject::EObject()<BR> {<BR> m_ID = -1;<BR> m_location = m_name = NULL;<BR> m_center = AcGePoint3d::kOrigin;<BR> acutPrintf("1eee\n");<BR> }</P>
