10.28在菜单项的响应函数中，如何调用自定义函数？

huangyhg

1.菜单响应函数onCommand

void defaultContext::onCommand(Adesk::UInt32 cmdIndex)
{AcDbObjectId         createLine();}   
//不能AcDbObjectId         createLine();这样函数声明？还是其他.....？
//程序执行时为何不跳转到2所列的函数体内？
2.紧接着在同一cpp文件里定义函数createLine的操作——/画一直线(例程)
AcDbObjectId  createLine()
{
        acutPrintf("ssssssssss");
       
        AcGePoint3d start(200,200,0);
                AcGePoint3d end(400,200,0);
        AcDbLine *pfcf=new AcDbLine(start,end);


AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable,AcDb::kForRead);
  AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
  pBlockTable->close();
AcDbObjectId fcfId;
pBlockTableRecord->appendAcDbEntity(fcfId,pfcf);
pBlockTableRecord->close();
  pfcf->close();
  return fcfId;
}

3.报错
Linking...
   Creating library Debug/contextmenu.lib and object Debug/contextmenu.exp
defaultarx.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall AcGePoint3d::AcGePoint3d(double,double,double)" (__imp_??0AcGePoint3d@@QAE@NNN@Z)
Debug/contextmenu.arx : fatal error LNK1120: 1 unresolved externals

contextmenu.arx - 2 error(s), 0 warning(s)
4.我都糊涂了，vc不可以在某个函数体内再调用自定义函数？

void defaultContext::onCommand(Adesk::UInt32 cmdIndex)
{
acutPrintf("ssssssssss");

AcGePoint3d start(200,200,0);
                AcGePoint3d end(400,200,0);
AcDbLine *pfcf=new AcDbLine(start,end);


AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable,AcDb::kForRead);
  AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
  pBlockTable->close();
AcDbObjectId fcfId;
pBlockTableRecord->appendAcDbEntity(fcfId,pfcf);
pBlockTableRecord->close();
  pfcf->close();
}
//试试看看，
//defaultContext::onCommand(Adesk::UInt32 cmdIndex)
//错误的原因好象是上面一句话，因为defaultContext类中无成员函数
//AcDbObjectId  createLine()
//可以用判断cmdIndex来对不同的菜单项定义不同的操作，否则对于所有的菜单操作一样
//试试看看

AcDbObjectId  createLine() 首先定义一下看看
