[vtkusers] vtkImageViewerWidget Trouble

[Mauricio Caliggiuri Inforcati]

Hi,

I am using vtkImageViewerWidget to show some vtk slices images.
When trying to execute my PYTHON script, sometimes the image frame is not 
showed.. Then, I execute the script again and the viewer is "Rendered" 
correctly.
Whats is wrong with this?


-I use a Toplevel and a Frame in it.
-Then a read the images with vtkImageReader.
-viewer is created as a vtkImageViewer instance
> result = vtkImageViewerWidget(....)
> result.pack(...)

thanks for helping,

  Mauricio
