[vtkusers] TkImageViewerWidget...

[Marcelo]

    Hi,

    I've received this message: 

Generic Warning: In
/home/ailton/VTK-4.2.2/Rendering/vtkTkImageViewerWidget.cxx, line 357
A TkImageViewerWidget is being destroyed before it associated
vtkImageViewer is destroyed. This is very bad and usually due to the
order in which objects are being destroyed. Always destroy the
vtkImageViewer before destroying the user interface components.

    How can I destroy vtkImageViewer??? 

    Thank you!

    Marcelo
