CATIA二次开发入门教程---16 通过点击屏幕创建线
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
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)
//获得Editor
