[vtkusers] growing RAM memory

[G G]

Thank you for answer. Do you give me some other hint, please? I rewrite to
this

void Window::widgetInicialization(QVTKWidget *widget)
{
    vtkSmartPointer<vtkRenderWindow> renwin =
vtkSmartPointer<vtkRenderWindow>::New();
    vtkSmartPointer<vtkRenderer> ren = vtkSmartPointer<vtkRenderer>::New();
    ren->SetBackground(1,1,1); // inicial white background
    renwin->AddRenderer(ren);
    widget->SetRenderWindow(renwin);
    widget->update();
    //renwin->Delete();
}

But I didnt free memory :( When I load image I gave about 40MB in RAM
memory. When I load new image memory increase for example to 80MB (it
depends which data is used)

When I load more data image program have 1,4GB RAM :(

Thank you for each answer
