标题: CAA中怎样得到工程图上点的坐标?
我在工程图中生成了一个点,然后想用鼠标点击选择,得到点的坐标,可是总出问题得不到,劳烦各位帮我看看,谢了~~

....
CATFeatureImportAgent * _ObjectAgent;

_ObjectAgent  = new CATFeatureImportAgent ( "

ointAgent", NULL, NULL, NULL, NULL, NULL) ;

   _ObjectAgent -> SetElementType ( "CATI2DPoint"  );
   _ObjectAgent -> SetBehavior    ( CATDlgEngWithPrevaluation | CATDlgEngAcceptOnPrevaluate | CATDlgEngWithUndo | CATDlgEngWithPSOHSO | CATDlgEngOneShot);
   _ObjectAgent -> SetAgentBehavior ( MfPermanentBody  | MfLastFeatureSupport | MfRelimitedFeaturization );

   // Point selection state
   CATDialogState *pState1= GetInitialState("Select a point ");
   pState1 -> AddDialogAgent ( _ObjectAgent );

   //-----------------------------------------------------------------------------
   // Transitions
   AddTransition ( pState1 , NULL ,
                  IsOutputSetCondition ( _ObjectAgent ) ,
                  Action ( ( ActionMethod ) [$DmCmd::GetPoint ) )]
....

CATBoolean DmCmd::GetPoint( void *data )
{
   CATPathElement* iPath=NULL;
   iPath = _ObjectAgent->GetValue();
   CATBaseUnknown * pObject2D = _ObjectAgent->GetElementValue(iPath);
   CATMathPoint2D * pPoint = (CATMathPoint2D *) pObject2D;

   x = pPoint->GetX();
   y = pPoint->GetY();

   _ObjectAgent -> InitializeAcquisition();
   return TRUE;
}
