选择product下的某个对象

求part1和part2中心的距离
现在就是选择part1和part2的问题
发现现在只有点击树上的名字才能选中，在对话框中显示part1.1和part2.2，如图1
如果直接点击模型，反而不能显示，如图2，似乎点击模型时只选中了面，不知道怎么上传图。。。笨死啦。。。
请问该怎么设置？才能不管是点击树还是模型都能在对话框中显示模型的名字


我现在写的程序是
{
_Body1Agent = new CATPathElementAgent ("Body1Agent");

_Body1Agent -> SetBehavior( CATDlgEngRepeat|CATDlgEngWithPSOHSO
);


_Body2Agent = new CATPathElementAgent ("Body2Agent");

_Body2Agent -> SetBehavior( CATDlgEngRepeat|CATDlgEngWithPSOHSO
);


_OKAgent=
new CATDialogAgent("OK Agent");

_OKAgent->AcceptOnNotify ( _Panel, _Panel->GetDiaOKNotification());


_CancelAgent=
new CATDialogAgent("Cancel Agent");

_CancelAgent->AcceptOnNotify ( _Panel, _Panel->GetDiaCANCELNotification());


// Define State

CATDialogState * FirstState = GetInitialState(" Select a Body1 ");

CATDialogState * SecState = AddDialogState(" Select a Body2 ");


// Plug Agent to the State

FirstState -> AddDialogAgent (_Body1Agent);

FirstState -> AddDialogAgent (_Body2Agent);

FirstState -> AddDialogAgent (_CancelAgent);


SecState -> AddDialogAgent (_Body2Agent);

SecState -> AddDialogAgent (_OKAgent);

SecState -> AddDialogAgent (_CancelAgent);


// Define transiton with condition and Action( optional)

AddTransition( FirstState, SecState,

IsOutputSetCondition (_Body1Agent),

Action ((ActionMethod) &FirstSpringBpdCmd::ActionOne));


AddTransition( SecState,SecState,

IsOutputSetCondition (_Body2Agent),

Action ((ActionMethod) &FirstSpringBpdCmd::ActionTwo));



AddTransition(SecState, NULL,

IsOutputSetCondition (_OKAgent),

Action ((ActionMethod) &FirstSpringBpdCmd::OKAction));

AddTransition( SecState, NULL,

IsOutputSetCondition (_CancelAgent),

Action ((ActionMethod) &FirstSpringBpdCmd::CancelAction));
}

ActionOne 函数里是这样写的：
ActionOne( void *data )
{

cout<< " Action one "<<endl;

//retrieve new selected

CATBaseUnknown *piUnknown = _Body1Agent->GetElementValue();

_spBody1 = NULL_var;

_spBody1 = piUnknown;

CATISpecObject_var spSpecOnBody1 =_spBody1;

_SelectorList003->SetLine(spSpecOnBody1->GetName(),0,CATDlgDataModify);

// Initiliase the acquisition

_Body1Agent->InitializeAcquisition();


return TRUE;
}
