[vtkusers] Issue with VTK and windows 64BIT

[L.J. van Ruijven]

Hello David,

Class vtkWin32OpenGLRenderWindow reserves extra bytes in its window 
class. I use vtkWndOffset as an offset into this buffer. Comming to 
think of it, the change I mentioned must also be applied to class 
vtkWin32OpenGLRenderWindow.
I did not save the original code, so I give you the places where 
vtkWndOffset occurs in my current code. In class 
vtkWin32OpenGLRenderWindow I use vtkWndOffset in the method WndProc in 
the statement

  vtkWin32OpenGLRenderWindow *me = 
    (vtkWin32OpenGLRenderWindow *)vtkGetWindowLong(hWnd,vtkWndOffset);

in the method CreateAWindow in the statements

      wndClass.cbWndExtra = 2 * vtkWndOffset;

    vtkSetWindowLong(this->WindowId,vtkWndOffset,(vtkLONG)this);

and finally in the method Finalize in the statement

      vtkSetWindowLong(this->WindowId,vtkWndOffset,(vtkLONG)0);


In class vtkWin32RenderWindowInteractor I use vtkWndOffset in its 
destructor in the statement

    tmp = (vtkWin32OpenGLRenderWindow *)(vtkGetWindowLong(this-
>WindowId,vtkWndOffset));

in the method Enable in the statement

    tmp=(vtkWin32OpenGLRenderWindow *)vtkGetWindowLong(this-
>WindowId,vtkWndOffset);

and in the method Disable in the statement

    tmp = (vtkWin32OpenGLRenderWindow *)vtkGetWindowLong(this-
>WindowId,vtkWndOffset);

Finally, I use vtkWndOffset in the procudure vtkHandleMessage in the 
statement 

  ren = (vtkWin32OpenGLRenderWindow *)vtkGetWindowLong
(hWnd,vtkWndOffset);

Hope this answers your question.

Leo van Ruijven.
