[vtkusers] VTK- MFC example Interactor Style

[Suresh]

Hi all,

I'm new to VTK. 
It will be great if any body could help with some issues.
First i 'm trying to add user interface to VTK using MFC.
I looked at the examples by VTK vtkSDI, vtkMDI and sample MFC. The problem i'm facing is,

I would like to intercept the events to RenderWindow conditionally,  have my own behaviour, and /OR pass the event to the VTK default handler. 
When i put my handler in WindowProc i could not pass the event to VTK.
I tried with have my own implementation of InteractorStyle and set the sam to Interactor object.
But then, either my Style handler is not called nor the default VTK behaviour is not showing up...

What happening?? Do i need to do any thing else.I modified the vtkSDI example for the above experiment..

Please somebody help me out..

Thanks.
