AW: AW: [vtkusers] Error message when the application is ended

[jiang]

Hi, David,
Thank you for your hint. I look through my code. There is no such registered
object in my code.
It is really strange. Could you tell me if there are some other cases that
will cause my problem?
Why is VTK so strict for its objects?

Thanks again!

Chunyan Jiang

  assume you have something like this
  case 1)

  vtkRenderer *rn=vtkRenderer::New();
  vtkRenderer *temp;
  temp=rn;/// when you do something like this then you have to register
  rn->Register(this);//this increases ref count of rn by 1

  //later when you no longer need temp you do

  temp->Delete();// now ref count of rn is reduced by one

  case2)
  the other way is to not register and not delete

  vtkRenderer *rn=vtkRenderer::New();
  vtkRenderer *temp;
  temp=rn;
  //forget about Register() and Delete(),but this is not a good way
