[vtkusers] Delete vtkObjects

[Mathieu Malaterre]

Andreas,

  I you are using MFC, I suggest to read the following post:

http://www.vtk.org/pipermail/vtkusers/2007-May/090968.html

  The non-compiling example you posted looks fine to me.

I created some vtk objects in the constructor and call the Delete() method in the destructor for testing. Than i created one of these class and delete  it while i checked the private bytes history on Sysinternals ProcessExplorer(which is by the way a great tool). I also enabled VTK_DEGUG_LEAKS.
> I thought when i delete the class the whole vtk stuff is gone but it is not. i can see no memory reduction in the process explorer and the DebugLeaks MessageBox tells me that always the objects remains. When i create a vtkPolyDataMapper there are even more. If i create more of my vtkClasses there are no changes in the memory but the debugleaks MessageBox report that all the vtkObjects remain in memory.
