[vtkusers] Serious leaks in all vtk versions

[Mathieu Malaterre]

Ali,

	When you build VTK, you may want to turn VTK_DEBUG_LEAKS:ON (this is in 
advanced option). Therfore when you write your own example you won't 
forget to delete vtk object.

	BTW I didn't /really/ send you the same message two times, I am used to 
do reply all so that vtkusers also benefit from your question/answer.

	Finally please find attached the correct vtk example

Mathieu


#include "vtkSphereSource.h"
#include "vtkPolyDataMapper.h"
#include "vtkActor.h"
#include "vtkRenderWindow.h"
#include "vtkRenderer.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkProperty.h"

int main ()
{

   // create sphere geometry
   vtkSphereSource *sphere = vtkSphereSource::New();
   sphere->SetRadius(1.0);
   sphere->SetThetaResolution(18);
   sphere->SetPhiResolution(18);

   // map to graphics library
   vtkPolyDataMapper *map = vtkPolyDataMapper::New();
   map->SetInput(sphere->GetOutput());

   // actor coordinates geometry, properties, transformation
   vtkActor *aSphere = vtkActor::New();
   aSphere->SetMapper(map);
   aSphere->GetProperty()->SetColor(0,0,1); // sphere color blue

   // a renderer and render window
   vtkRenderer *ren1 = vtkRenderer::New();
   vtkRenderWindow *renWin = vtkRenderWindow::New();
   renWin->AddRenderer(ren1);

   // an interactor
   vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
   iren->SetRenderWindow(renWin);

   // add the actor to the scene
   ren1->AddActor(aSphere);
   ren1->SetBackground(1,1,1); // Background color white

   // render an image (lights and cameras are created automatically)
   renWin->Render();

   // begin mouse interaction
   iren->Start();

  sphere->Delete();
  map->Delete();
  aSphere->Delete();
  ren1->Delete();
  iren->Delete();
  renWin->Delete();

   return 0;
}
