[vtkusers] Error while close the VTK Window

[Sathish Kumar]

Hi Sebastien,

I accept your point. But it works without *memory leak*. Thats why I 
choosed DeleteAll() method. Anyway here after I won't use that.

As per your suggestion I tried the following code in Windows.
This too gives the same error window which is attached in the previous mail.

private void formWindowClosed(java.awt.event.WindowEvent evt) {
         // Garbage Collection...
         vpanAxial.GetRenderer().RemoveAllViewProps();
         vpanAxial.GetRenderer().RemoveAllLights();
         
vpanAxial.GetRenderWindow().RemoveRenderer(vpanAxial.GetRenderer());
         vpanAxial = null;
         vpanCoronal.GetRenderer().RemoveAllViewProps();
         vpanCoronal.GetRenderer().RemoveAllLights();
         
vpanCoronal.GetRenderWindow().RemoveRenderer(vpanCoronal.GetRenderer());
         vpanCoronal = null;
         vpanSagittal.GetRenderer().RemoveAllViewProps();
         vpanSagittal.GetRenderer().RemoveAllLights();
         
vpanSagittal.GetRenderWindow().RemoveRenderer(vpanSagittal.GetRenderer());
         vpanSagittal = null;

         resliceAxial = null;
         resliceCoronal = null;
         resliceSagittal = null;
         actorAxial = null;
         actorCoronal = null;
         actorSagittal = null;
         reader = null;

         System.gc();
         vtkGlobalJavaHash.GC();
     }

Thanks,
Sathish
