[vtkusers] interaction off

[Gopalakrishnan, Gowri]

In c++ console application if I use renderwindow and not use the
renderwindow
interactor then the renderwindow flashes for a fraction of a second and then

vanishes. Unless you use the windowinteractor iren->start the image does not

stay on the screen. This leads to the problem of vtk handling the events 
when I dont want it to. Is there a method such as iren->turnInteractionOff.
I saw a method InteractionOff and used it, but it did not produce anything.
My
mouse events were still going to vtk. 

If anyone thinks otherwise I would be happy to learn the behaviour of vtk
with
c++ applications. 

Thanks Prabhu for your help
Regards
Gowri

If you use the vtkRenderWindow and dont use the RenderWIndowInteractor
I dont think any of the events are captured.  This is what the Tk,
GTK, wx widgets under Python do.  They embed a vtkRenderWindow inside
a native widget and then trap the various events in the native gui
toolkit.  So VTK doesnt process the events at all.

OTOH if you want to use something like the interactor and turn it on
and off - I dont know the answer off hand.
