[vtkusers] Memory management

[Jothybasu Selvaraj]

Dear All

I am not familiar with c++, so I would like to have your suggestion in
memory management in VTK/Qt.


I have a class to read a series of CT images constructed like this

DICOMReader::DICOMReader(QWidget *parent)

{

    this->ImageSet=vtkSmartPointer<vtkImageData>::New();

    }


DICOMReader::~DICOMReader()

{


}


void DICOMReader::readImageSeries()

{//reading code goes here, only the last filter is shown here

     typedef itk::ImageToVTKImageFilter<InputImageType> ConnectorType;

    ConnectorType::Pointer Converter = ConnectorType::New();

    Converter->SetInput(reader->GetOutput());

    Converter->Update();

    this->ImageSet=Converter->GetOutput();

}


then I pass this image to a viewer class like this:


//Read image

    DICOMReader *reader=new DICOMReader(this);

    reader->readImageSeries();


ImageViewer2D *ViewerEBRT= new ImageViewer2D();

ViewerEBRT->SetImageData(reader->ImageSet);


SetImageData is defined as


void ImageViewer2D::SetImageData(vtkImageData *Img)

{

    this->ImageData=Img;

}


Looks likes there is some silly mistake they way data is passed on.


Can anyone suggest me a better way.




Thanks
