CATIA二次开发入门教程---15 通过点击屏幕创建点
CATIA二次开发入门教程---15 通过点击屏幕创建点通过点击屏幕，自动创建点， 这里直接建立了一个简单的对话框，通过pushbutton来添加一个回掉函数，函数里面去执行创建点的类。
void DialogTestCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
// Add your code here
CreatePointCmd *createPoint = new CreatePointCmd();
}
新建一个catia 的命令，名称为 CreatePointCmd ，接下来要做的就是在 action one 里面进行点的创建，代码如下：
CATBoolean CreatePointCmd::ActionOne( void *data )
{
// TODO: Define the action associated with the transition
// ------------------------------------------------------
CATMathPoint2D point2D =_Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);
cout<<"Point coordinates:" << point3D.GetX() << "," << point3D.GetY() << "," << point3D.GetZ()<<endl;
//设置Container(非根节点)
//获得Editor
CATFrmEditor* pEditor = CATFrmEditor::GetCurrentEditor();
//得到当前对象的文档
CATDocument * pDocument = NULL ;
//取得当前活动对象
CATPathElement activePath = pEditor->GetUIActiveObject();
//取得当前活动的product
CATIProduct *pActiveProduct = (CATIProduct *)activePath.SearchObject(CATIProduct::ClassName());
//当前活动对象不存在
if (pActiveProduct == NULL)
{
pDocument = pEditor->GetDocument();
}
else
{
CATIProduct_var spRef = pActiveProduct->GetReferenceProduct();
//当前对象的引用对象是否存在
if ( NULL_var == spRef )
{
return FALSE;
}
//当前对象的链接对象
CATILinkableObject * piLinkableObject = NULL;
HRESULT rc = spRef->QueryInterface( IID_CATILinkableObject, (void**)& piLinkableObject );
if ( FAILED(rc) )
{
piLinkableObject->Release();
piLinkableObject = NULL ;
return FALSE;
}
//得到当前对象的文档
pDocument = piLinkableObject->GetDocument();
piLinkableObject->Release();
piLinkableObject = NULL ;
if ( NULL == pDocument)
{
return FALSE;
}
}
//得到文档容器集
CATIContainerOfDocument * pIContainerOfDocument = NULL;
HRESULT rc = pDocument->QueryInterface(IID_CATIContainerOfDocument, (void**)&pIContainerOfDocument);
if (FAILED(rc))
{
//pIContainerOfDocument->Release();
pIContainerOfDocument = NULL ;
return FALSE;
}
//获得Document
CATIContainer* _pContainer = NULL;
//获得SpecContainer
HRESULT hr = pIContainerOfDocument->GetSpecContainer(_pContainer);
//GSM工厂
CATIGSMFactory_var spGSMFactory = NULL_var;
//设置工厂
spGSMFactory = _pContainer;
CATIGSMPoint_var spPoint = spGSMFactory->CreatePoint(point3D);
CATISpecObject_var spSpecPoint= spPoint;
CATIGSMProceduralView_var spSndPntObj = spSpecPoint;
//*将点显示在屏幕上
spSndPntObj->InsertInProceduralView();
//更新点对象
spSpecPoint->Update();
return TRUE;
}
效果如下：
_Indication指的是什么呀
