CATIA二次开发入门教程---16 通过点击屏幕创建线

和上面例子类似，这里需要手动添加一些action事件，在头文件里面新增加一个 indication，效果如下
create line.PNG

代码如下：

//-------------------------------------------------------------------------
// Constructor
//-------------------------------------------------------------------------
CreateLineCmd::CreateLineCmd() :
  CATStateCommand ("CreateLineCmd", CATDlgEngOneShot, CATCommandModeExclusive)
//  Valid states are CATDlgEngOneShot and CATDlgEngRepeat
  ,_IndicationPoint1(NULL) ,_IndicationPoint2(NULL)
{
}
//-------------------------------------------------------------------------
// Destructor
//-------------------------------------------------------------------------
CreateLineCmd::~CreateLineCmd()
{
if (_IndicationPoint1!= NULL)
   _IndicationPoint1->RequestDelayedDestruction();
if (_IndicationPoint2!= NULL)
_IndicationPoint2->RequestDelayedDestruction();

}

//-------------------------------------------------------------------------
// BuildGraph()
//-------------------------------------------------------------------------
void CreateLineCmd::BuildGraph()
{

  // TODO: Define the StateChart
  // ---------------------------
  _IndicationPoint1 = new CATIndicationAgent ("IndicationOne");
  AddCSOClient(_IndicationPoint1);
  _IndicationPoint2 = new CATIndicationAgent ("IndicationTwo");
  CATMathPlane PlaneXY;
  _IndicationPoint1 -> SetMathPlane (PlaneXY);
  _IndicationPoint2 -> SetMathPlane (PlaneXY);
  CATDialogState * initialState1 = GetInitialState("select first point");
  initialState1 -> AddDialogAgent (_IndicationPoint1);

  CATDialogState * initialState2 = AddDialogState("select second point"); // add important
  initialState2 -> AddDialogAgent (_IndicationPoint2);


  AddTransition( initialState1, initialState2,
               IsOutputSetCondition (_IndicationPoint1),
               Action ((ActionMethod) &CreateLineCmd::ActionOne));

  AddTransition( initialState2, NULL,
IsOutputSetCondition (_IndicationPoint2),
Action ((ActionMethod) &CreateLineCmd::ActionTwo));
}

//-------------------------------------------------------------------------
// ActionOne ()
//-------------------------------------------------------------------------
CATBoolean CreateLineCmd::ActionOne( void *data )
{
  // TODO: Define the action associated with the transition
  // ------------------------------------------------------

  CATMathPoint Point3D;
  CATMathPlane Plane = _IndicationPoint1->GetMathPlane();

  //设置Container(非根节点)
